What is the solution to
Multiply (Y-1)(y+8)

Answer:

$100

Step-by-step explanation:

We know that the total cost was $110 and that the phone is $100 more than the case. With this, we can figure out how much the case is, and use that information to find the price of the phone.

Case price = total price - 100

= 110 - 100

Case price = 10

Now that we know that the case price is $10, we can figure out the phone's price.

Phone price = total price - case price

= 110 - 10

= 100

The phone costs $100

3.865in^2

It's (the area of the square minus the area of the circle) divided by 2.

So, Area of the square is 6x6=36

Area of the circle is (pi)*(radius=3)^2=28.27

36-28.27=7.73

7.73/2=3.865in^2

Median = $80,000 ; Mean = $84,000 ; Q1 = 67,000 ; Q3 = 106,000

Step-by-step explanation:

Given the data :

108 83 106 73 53 85 80 63 67 75 124 55 93 118 77

Reorderd data :

53, 55, 63, 67, 73, 75, 77, 80, 83, 85, 93, 106, 108, 118, 124

The median salary:

1/2(n+1)th term

Sample size, n = 15

1/2 (15 + 1)th term

1/2(16)th term

8th term = 80

Median is $80,000

Median reported by Wall Street Journal approximately $85000

The obtained and reported values are close

The mean annual salary :

ΣX / n = 1260 / 15 = 84

Mean annual salary = $84,000

Mean is the average of all earnings combined, median is the mid value of he data.

First and third quartile :

Q1 = 1/4(n+1)th term

Q1 = 1/4(16)th term

Q1 = 4th term = 67

Third quartile:.

Q3 = 3/4(n+1)th term

Q3 = 3/4(16)th term

Q3 = 12th term = 106

Answer:

8 quarts

Step-by-step explanation:

Step One: Figure out how much 40% is by making an equation:

Since we are looking for a percentage, we use cross multiplication to find X.

[tex]\frac{x}{20} = \frac{40}{100}[/tex]

Step Two: multiply 20 by 40 to start cross multiplying:

20 times 40 is 800, so replace the 40 by 800 in the equation.

[tex]\frac{x}{20} = \frac{800}{100}[/tex]

Step Three: divide 800 by 100, and we will have X:

800/100=8

X=8 aka 8 quarts

Answer:

The chance that the usual language in that household will NOT be English = 0.4

Step-by-step explanation:

As given ,

Total households in which languages spoken is English = 180

Total households in which languages spoken is Spanish = 80

Total households in which languages spoken is other than English or Spanish  = 40

So,

Total households = 180 + 80 + 40 = 300

Now,

Household in which English language is not spoken = 80 + 40 = 120

So,

The chances that the usual language in that household will NOT be English = [tex]\frac{120}{300} = \frac{12}{30} = \frac{4}{10} = 0.4[/tex]

∴ we get

The chance that the usual language in that household will NOT be English = 0.4

In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at.

on the 3rd week Kappa weighed 11

and 2nd week Kappa weighed 5

and 1st week Kappa weighed 3

Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier.

Answer:

Step-by-step explanation:

a). Since, 20% of the total diagram is represented by one fifth part of the total length.

Therefore, by adding all parts we will get 100% weight of the adult puppy.

20% of the part = 9 pounds

So the total weight of the adult puppy = 9 + 9 + 9 + 9 + 9

                                                         = 45 pounds

b). Weight of the puppy =  9 pounds

    Weight of a adult = 45 pounds

    Therefore, fraction that represents the weight of the puppy as compared to the weight of an adult = [tex]\frac{9}{45}[/tex]

                                         = [tex]\frac{1}{5}[/tex]

Answer:

Question 1 Answer: The adult weight will be 45 pounds.

Question 2 Answer: The puppy is ⅕ of its adult weight.

Step-by-step explanation:

Q1- Why is the answer: because there are 5 9's and 5 ⋅ 9 = 45.

Q2-why is the answer : because the whole is divided into 5 pieces of equal length.

Answer:

[tex](x+12)^2+(y-5)^2=80[/tex]

Step-by-step explanation:

First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is [tex]\sqrt{4^2+8^2}=\sqrt{80}[/tex].

The equation of a circle with diameter endpoints of (-14,1) and (-10,9) are;

(x+1)²+(y-4)²=348.

The standard form of the equation of a circle is (x - h)² + (y - k)² + r², where (h, k) is the center of the circle, and r is its radius.

Find the distance AB

d=√[(9 + 14)²+(-10 - 1)²]

d=√[576+121]

d=√697 units

The diameter=√697 units

r=√697/2  unit

Thus, the center of the circle is (-1,4)

Hence, the equation of a circle

(x-h)²+(y-k)²=r²

(x+1)²+(y-4)²=(√697/2)²

(x+1)²+(y-4)²=348

Answer:

CD = 8 cm

Step-by-step explanation:

Given

See attachment

[tex]AE=6 cm,\ ED=4 cm,\ AB=4.5 cm,\ BE=4.8 cm.[/tex]

Required

Find CD

To calculate CD, we first calculate BC using the following equivalent ratio

[tex]AB : BC = AE:ED[/tex]

Substitute values for AB, AE and ED

[tex]4.5 : BC = 6 : 4[/tex]

Express as fraction

[tex]\frac{4.5 }{ BC} = \frac{6 }{ 4}[/tex]

Cross Multiply

[tex]BC * 6 = 4.5 * 4[/tex]

[tex]BC * 6 = 18[/tex]

Divide through by 6

[tex]BC = 3[/tex]

To calculate CD,

We make use of the following equivalent ratio

[tex]AB : BE = AC : CD[/tex]

Where

[tex]AC = AB + BC[/tex]

[tex]AC = 4.5 + 3[/tex]

[tex]AC = 7.5[/tex]

So, we have:

[tex]AB : BE = AC : CD[/tex]

[tex]4.5 : 4.8 = 7.5 : CD[/tex]

Express as fraction

[tex]\frac{4.5 }{ 4.8 }= \frac{7.5 }{ CD}[/tex]

Cross Multiply

[tex]4.5 * CD = 7.5 * 4.8[/tex]

Divide through by 4.5

[tex]CD = \frac{7.5 * 4.8}{4.5}[/tex]

[tex]CD = \frac{36}{4.5}[/tex]

[tex]CD = 8[/tex]

Answer:

35.56 (rounded to nearest hundredth)

Step-by-step explanation:

1.8x = 64

x= 64/1.8

x = 35.56

Answer:

x = 65

Step-by-step explanation:

To solve the equation, we write it in radical form:

[tex]5\, \sqrt[3]{x-1} = 20[/tex]

Then, we divide both sides by 5 to isolate the root:

[tex]\sqrt[3]{x-1} = \frac{20}{5} \\\sqrt[3]{x-1} =4[/tex]

and next, we raise both sides of the equation to the power 3 so as to free the expression in x from the root:

[tex]x-1=4^3\\x-1=64[/tex]

now we add 1 to both sides to isolate x:

x = 65

Answer:

Answer:

3.51% probability that this fund-raising event is a success

Step-by-step explanation:

In a set with mean  and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Answer:

The angle of elevation of the pile is 30°

Step-by-step explanation:

Given that;

Height = 15 ft

Diameter = 52 ft

so radius r = D/2 = 52/2 = 26 ft

Now, to get the angle of elevation.

given the details in the question,

we can say; the given height is the opposite which is 15 ft.

Also the radius is adjacent which is 26 ft

using SOH CAH TOA

TOA; Tan = Opposite / Adjacent

so

tan∅ = 15 ft / 26 ft

tan∅ = 0.5769

∅ = tan⁻¹( 0.5769 )

∅ = 29.98° ≈ 30°

Therefore, The angle of elevation of the pile is 30°

Step-by-step explanation:

The probability for exact 4 chickens being infected out of the 7 is ⁷C₄(0.15)⁴(0.85)³. The correct option is (A).

The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.

In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.

Given that,

The probability of the infected chicken is 15%.

Which can be written as,

P(infected) = 15%

                  = 15/100

                  = 0.15

Then, the probability of not getting infected chicken is,

P(not infected) = 1 - 0.15

                        = 0.85

The total number of chicken for test = 7.

Now, in order to find the probability of the exact 4 infected chickens, binomial distribution can be used as.

The general expression for binomial distribution is ⁿCₓpˣqⁿ⁻ˣ.

For the given case p = P(infected) and q = P(not infected), n = 7 and x = 4.

Thus, the probability is given as,

P(Exact 4 are infected) = ⁷C₄(0.15)⁴(0.85)³

Hence, the  probability that exactly 4 of the 7 chickens sampled have the virus is  ⁷C₄(0.15)⁴(0.85)³.

Pie chart will show that Claire spent about 33.3% of her time sleeping, The pie chart will have five sections, Twenty-four hours will be equivalent to 100% in the pie chart.

The "pie chart," which divides the circular statistical graphic into sectors or sections to illustrate the numerical problems, is also known as a "circle chart." A proportionate portion of the total is denoted by each sector. At that point, the pie chart is the most effective method for determining something's composition.

Given 24 hours schedule of Clair in which,

school time is 8 hours, playing time is 4 hours, homework time is 2 hours, sleeping time is 8 hours and chores time is 2 hours.

if we calculate total time in percentage than 24 hours will be equal to 100%

and their will be 5 sections in chart,

equivalent time for school in percent is 100/24 x 8 =33.33%

equivalent time for sleeping in percent is 100/24 x 8 =33.33%

equivalent time for homework in percent is 100/24 x 2 = 8.33%

equivalent time for chores in percent is 100/24 x 2 = 8.33%

equivalent time for playing in percent is 100/24 x 4 = 16.66%

Hence the pie chart will have 5 sections and sleeping time will be 33.33%.
