Answer:
4.12
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 8^2 = 9^2
a^2 + 64 = 81
-64 -64
a^2 = 17
square root of 17 = 4.12310
round to the nearest hundredth 4.12
A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers the color green. If 15 buyers are randomly selected, what is the probability that exactly a third of the buyers would prefer green?
Answer:
0.09
Step-by-step explanation:
Given that 50% of this population prefers the color green.
Let p the probability that one person selected from the population prefer the green color of the car. So,
p=0.05
There is only two chance, any person either prefer the green color or not, assuming this holds true for every person, so the mentioned population can be assumed as Bernoulli's population.
By using Bernoulli's theorem, the probability of exactly r success of n randomly selected from the Bernoulli's population is
[tex]P(r)=\binom{n}{r}p^{r}{(1-p)}^{n-r}\cdots(i)[/tex]
Here, 15 buyers are randomly selected, so, n= 15 and
[tex]r= \frac1 3 \times 15=5[/tex]
So, by using equation (i), the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is
[tex]P(r=5)=\binom{15}{5}(0.5)^{5}{(1-0.5)}^{15-5}[/tex]
[tex]=\binom{15}{5}(0.5)^{5}{0.5}^{10}[/tex]
[tex]=\binom{15}{5}(0.5)^{15}[/tex]
=0.0916
Hence, the probability that exactly 5 buyers would prefer green out of 15 randomly selected buyers is 0.09.

A number line going from negative 30 to positive 30. An arrow goes from 5 to 10, from 10 to 15, from 15 to 20.
Emily used the number line to find the quotient for -15 ÷ 5. What errors did she make? Select three correct answers.
The arrows should point in the negative direction.
The small arrows should end in the same place as the large one.
The arrows should end on negative 15.
The arrows should start at zero.
There should be 5 small arrows.
Answer:
-3 is the answer because if we divide 15 by 5 we get 3 . So it is same only the question is -15 divide by 5 so the answer is -3

Step-by-step explanation:
which could be the function graphed below?
f(x) = √x - 5+1
f(x) = √x-2
f(x) = √x
f(x) = √x+4
Answer:
Option (4)
Step-by-step explanation:
Parent function of the graph attached,
f(x) = [tex]\sqrt{x}[/tex]
If the given function is shifted by 'a' units to the left,
Rule for the transformation is,
g(x) = f(x + a)
So the transformed function will be in the form of g(x) = [tex]\sqrt{x+a}[/tex]
Therefore, from the given options, f(x) = [tex]\sqrt{x+4}[/tex] will match our requirements.
Option (4) will be the answer.

Step-by-step explanation:
A restaurant chef ordered 4 pounds of beef at $3.25 per pound, 6 pounds of potatoes at $1.96 a pound, and 5 pounds of carrots at $1.81 per pound. He estimates that this will make 28 meals. If he charges $20 per meal, how much profit will he make for each meal?
Answer:
Profit = $18.8 per meal
Step-by-step explanation:
Chef ordered beef = 4 pounds
Cost of beef = $3.25 per pound
Total cost of beef = 4 × 3.25 = $13
Amount of potatoes ordered = 6 pounds
Cost of potatoes = $1.96 per pound
Total cost of potatoes = 6 × 1.96
= $11.76
Amount of carrots ordered = 5 pounds
Cost of carrots = $1.81 per pound
Total cost of carrots = 5 × 1.81 = $9.05
Total amount of beef, potatoes and carrots = $13 + $11.76 + $9.05
= $33.81
Number of meals prepared with material purchased = 28
Per meal cost = [tex]\frac{33.81}{28}[/tex] = $1.2075
Selling price of one meal = $20
Profit per meal = Selling price - Cost price
= 20 - 1.2075
= 18.7925
≈ $18.8
Therefore, he will make $18.8 for each meal.

a printer can print 12 pages in 9 seconds what is the closest estimate of the number of pages it can print in 1 min
Answer:
estimated number of pages it can print will 80 in 1 min.
Step-by-step explanation:
If 12 pages/9 Seconds then by multiplying by 60 secs as there are 60 secs in 1 min.
we get
12/9 then multiply by 60 you will get 80 pages in 1 minute.
Number of pages a printer can print in 9 seconds = 12 pages
Number of pages than can be printed in 1 second =
= 12/9
= 1.3 pages
Number of pages that can be printed in 1 second = 0.75 page
Number of pages that can be printed in 1 minute =
= 1 minute = 60 seconds
Number of pages that can be printed in 60 seconds =
= 1.3 × 60
= 78 pages
Rounding off 78 , we get 80 .
Therefore , 80 pages can be printed in 1 minute .

If 2x = 10, find the value of 1 - 2x
Answer:
2x=10
divide by 2
x=5
1-2x
1-2(5)
1-10
answer is -9
Answer:
-9
Step-by-step explanation:
First solve the equation, 2x=10 to get the value of x
2x = 10
x = 10÷ 2
x= 5
now, put this value of x in the expression 1-2x
1 - 2x
= 1- 2(5)
= 1- 10
= -9
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Answer: x = 60/11
Step-by-step explanation:
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Multiply the 1/2 with -10x, and -10.
Let's look on the side that we are working on now.
New equation:
- 1 + 4 (6x + 3) = -5x - 5 - 5
-5-5= -10
-1+4(6x+3)=-10-5x
Next we remove the brackets.
-1 + 4 * 6x + 3 = -10x -5
Now we bring the x's on one side and the non-x's on the other. When we bring a positive x on the other side of an equal sign, it becomes negative. If we bring a negative x on the other side of an equal sign, it becomes positive.
10x * 6x = 1 - 4 - 3 - 5
60x = 1 - 12
60x = -11
x = 60/11

7/11 ÷ 21/55 pls help me
9514 1404 393
Answer:
5/3
Step-by-step explanation:
You can divide fractions a couple of ways:
1. Invert the denominator and multiply
[tex]\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{7}{11}\times\dfrac{55}{21}=\dfrac{55\cdot7}{11\cdot21}=\boxed{\dfrac{5}{3}}[/tex]
2. Make both fractions have the same denominator and use the ratio of their numerators
[tex]\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{35}{55}\div\dfrac{21}{55}=\dfrac{35}{21}=\boxed{\dfrac{5}{3}}[/tex]

Answer:
x=-10
Step-by-step explanation:
15-2(x+5)=25
multiply the 2 by the x and 5 and you get
15-2x-10=25
since the 15 and the negative 10 are on the same side you add them together and get
5 -2x= 25
-5 -5
-2x =20
Then divide the -2/20= -10
Answer:
x = -10
Explanation:
15 - 2 ( x + 5 ) = 25
Distribute 2 through the parentheses
15 - 2x - 10 = 25
Subtract the numbers
5 - 2x = 25
Move constant to the right-hand side and change its sign
-2x = 25 - 5
Subtract the numbers
-2x = 20
Subtract both sides
x = -10
x/8 -4 =7/16 x=

Answer:
Exact form: x = [tex]\frac{-64}{5}[/tex]
Decimal form: x = -12.8
Mixed number form: x = -12[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
hope this helps :)
Answer:
x = - [tex]\frac{64}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{8}[/tex] - 4 = [tex]\frac{7}{16}[/tex] x ( multiply through by 16 to clear the fractions )
2x - 64 = 7x ( subtract 2x from both sides )
- 64 = 5x ( divide both sides by 5 )
- [tex]\frac{64}{5}[/tex] = x
