Answer 1

Answer:

x would be 54 degrees

Step-by-step explanation:

Since x lies on a straight line, and it gives you the other angle (126) just subtract 180 and 126.

180 - 126 = 54

Answer 2
x = 54 degrees

There is no solution to make it true.

Step-by-step explanation:

First you expand
24x - 48 = 24x + 48
Then you cancel 24x on both sides

Answer:

1. m<2 = 115 °

2. m<5 = 83 °

3. m<8 = 45 °

4. m<4 = 137 °

Step-by-step explanation:

1. Determination of m<2

m<1 = 115 °

m<2 =?

m<2 = m<1 (vertically opposite angles are equal)

m<2 = m<1

m<2 = 115 °

2. Determination of m<5

m<6 = 83 °

m<5 =?

m<5 = m<6 (vertically opposite angles are equal)

m<5 = m<6

m<5 = 83 °

3. Determination of m<8

m<9 = 45 °

m<8 =?

m<8 = m<9 (vertically opposite angles are equal)

m<8 = m<9

m<8 = 45 °

4. Determination of m<4

m<3 = 137 °

m<4 =?

m<4 = m<3 (vertically opposite angles are equal)

m<4 = m<3

m<4 = 137 °

hayden and jamie completed 20 math problems together, jamie completed 2 more than twice the number that hayden completed. Let p represent the number of math problems hayden completed. Write an equation that can be used to find the number of math problems that jamie completed.

Answers

Answer:

2p+2+p = 20

Step-by-step explanation:

Let p represent the number of Math problems Hayden completed.

Let 2p+2 represent the number of Math problems Jamie completed.

Next, we have to add them together so that the total Math problems they completed will be equal to 20.

Let's solve.

2p+2+p = 203p+2 = 203p = 20-23p = 18p = [tex]\frac{18}{3}[/tex]p = 6

Therefore, Hayden completed 6 Math problems.

Next, we have to get how many problems Jamie completed.

Let's solve.

2p+2 = ?2(6)+2 = ?12+2 = ?14

Therefore, Jamie completed 14 Math problems.

Let's check.

2p+2+p = 2014+6 = 2020 = 20

It's correct!

8. A drug and placebo were tested on 23 people each to study their effect on cholesterol. The mean cholesterol levels with the people on the new drug are 195 and SD of 35. The values for placebo sample are 245 and SD of 31. Using 5% level of significance, does the drug have effect on lowering the cholesterol.

Answers

Answer:

The drug have effect on lowering the cholesterol.

Step-by-step explanation:

H₀ : μ₁ - μ₂ = 0

⇒ H₀ : μ₁ =  μ₂

H₁ : μ₁ - μ₂ < 0

⇒H₁ : μ₁ <  μ₂

Now,

given , n₁ = 23 , n₂ = 23

∴ Degree of freedom = v = n₁ + n₂ - 2

                                         = 23 + 23 - 2 = 44

⇒v = 44

Now,

Given, level of significance = 5% = 0.05

For the given significance level, critical time t = 1.68

As

Decision rule states that'if t < 1.68 , reject H₀

Now,

For Drug:

mean = m₁ = 195

SD = d₁ = 35

People = n₁ = 23

For placebo :

mean = m₂ = 245

SD = d₂ = 31

People = n₂ = 23

Now,

Variance = [tex]\frac{(23-1)35^{2} + (23-1)31^{2} }{23 + 23 - 2}[/tex]  = 1093

Standard Deviation, S = 33.06

Point estimate = m₁ - m₂ = 195 - 245 = -50

Standard deviation error = S×([tex]\frac{1}{n_{1} } + \frac{1}{n_{2} }[/tex] ) = 9.75

Now,

Test statistics = [tex]-\frac{50}{\sqrt{9.75} } = -5.13[/tex]

⇒ t < 6.13

⇒Reject H₀

⇒The drug have effect on lowering the cholesterol.

Four friends go to dinner. Each chooses a different meal. When the check comes, they decide they will each pay the same amount. If the costs of the meals (including tax and tip) were $12.20, $11.00, $8.50, and $7.50, what should each friend pay so they cover the whole bill?​

Answers

Answer: Each friend should pay $9.80

Step-by-step explanation: First add up all their checks, then divide them by 4 (4 because there 4 friends) to get the amount each friend needs to pay.

$12.20 + $11.00 + $8.50 + $7.50= $39.20

39.30 / 4 = $9.80

a. The time for a computer algorithm to assign an image to a category.

Time can have decimal values, so continuous

b. The number of bytes used to store a file in a computer.

The number of bytes is never decimal, so discrete

c. The ozone concentration in micrograms per cubic meter.

Answers

Answer:

[tex]5\frac{5}{6}[/tex]

Step-by-step explanation:

The problem above requires the use of mathematical operation with mixed fractions. In order to do this, you have to convert the mixed fractions into improper fractions first.

Let's convert.

[tex]3\frac{1}{2}[/tex] = [tex]\frac{7}{2}[/tex][tex]1\frac{2}{3}[/tex] = [tex]\frac{5}{3}[/tex]

Next, you have to multiply the fractions by multiplying the numerators with each other and the denominators with each other.

Let's solve.

[tex]\frac{7}{2}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{35}{6}[/tex]

Since [tex]\frac{35}{6}[/tex] is an improper fraction and the choices above are mixed fractions, you have to convert it.

Let's convert.

[tex]\frac{35}{6}[/tex] = [tex]5\frac{5}{6}[/tex]

Therefore, the answer is [tex]5\frac{5}{6}[/tex]

ABC is a three digit number where each number represents a different digit. If A < C what is the greatest possible number?

Answers

Answer:

879

Step-by-step explanation:

Because C is greater than A, C has to be the largest possible number so that A can be as large as possible. because C is the largest possible number, which is 9, the next largest number is 8, which in this case is A. The next biggest number is 7 which is B.

To sum it all up, the number is 879.

how can you find the area of a circle? give me a good explanation please, ty!​

Answers

Answer:

The area of a circle is pi times the radius squared (Area = pi radius²).

Step-by-step explanation:

The circumference of a circle is the linear distance of a circle's edge. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.

The following equation describes the relation between the circumference and the radius R of a circle:

C = 2πR

Where π is a constant approximately equal to 3.14159265..

How to find the circumference of a circle

Determine the radius of a circle. Let's assume it's equal to 14 cm.

Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.

You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².

Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.

Use our circumference calculator to find the radius when you only have the circumference or area of a circle.

Answer:

Use this formula: A = π r²

Step-by-step explanation:

A = π r²

What does A = π r² mean? :

(Area = Pi x Radius²)

π = Pi (3.14)

² = squared
