Answer:

Y = 35 degrees

Step-by-step explanation:

The total degrees of a triangle always equal to 180. So here the question tells us the degree for 2 angles which is 60 and 85. From this, we can find the value of Y by subtracting: 180 - 60 - 85 = Y

35 = Y

What is the Pythagorean Theorem used for? What is the formula

saveliy_v [14]

The Pythagorean Theorem states that a triangle's hypotenuse is equal to the square's of the other two sides of the triangle.

a² + b² = c²
a = side of triangle
b = other side of triangle
c = hypotenuse (squared)

Find the square root to find the accurate length of the hypotenuse.

A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 1

Harman [31]

The probability that the mean clock life would differ from the population mean by greater than 12.5 years is 98.30%.

Given mean of 14 years, variance of 25 and sample size is 50.

We have to calculate the probability that the mean clock life would differ from the population mean by greater than 1.5 years.

μ=14,

σ= $\sqrt{25}$ =5

n=50

s orσ =5/ $\sqrt{50}$ =0.7071.

This is 1 subtracted by the p value of z when X=12.5.

So,

z=X-μ/σ

=12.5-14/0.7071

=-2.12

P value=0.0170

1-0.0170=0.9830

=98.30%

Hence the probability that the mean clock life would differ from the population mean by greater than 1.5 years is 98.30%.

Okay first off. You want to combine like terms.

2.75-1.5=1.25j
2.25+3=5.25

Now you just fit those two answers into the final answer and you have:

1.25j+5.25.

Lillian and Isabella went shopping for school supplies. Lillian found her favorite notebook on sale so she bought three of the e

ASHA 777 [7]

Answer:

Each girl had $7.50 when they arrived.

Step-by-step explanation:

We have to figure out what c (cost of each notebook) is first before we find out how much money each girl had. We also know they have the same money, so both sides are connected. The equation should be: 3x = x + 5.

3x = x + 5

First, subtract x from both sides. This cancels out the addition by x.

3x - x = 5

Now, subtract x from 3x. This equals 2x.

2x = 5

To cancel out the multiplication by 2, divide both sides by 2.

x = 5/2

Lastly, divide 5 by 2 to get 2.5.

x = 2.5

Substitute x for 2.5 in the earlier equation (3x = x + 5)

3(2.5) = 2.5 + 5

First, multiply 3 by 2.5 to get 7.5.

7.5 = 2.5 + 5

Add 2.5 to 5 to get 7.5.

7.5 = 7.5

Both sides are equal so we have our answer. So, both girls had $7.50 when they arrived at the store.
