Answer:

The correct option is 4.

Step-by-step explanation:

According to the Pythagoras theorem, the sum of squares of two legs of a triangle is equal to the square of the hypotenuse of the triangle.

(hypotenuse)^2=(leg_1)^2+(leg_2)^2

From the given figure it is clear that the length of one leg is 4 ft and the length of second leg is 7 ft.

Using Pythagoras theorem, we get

(hypotenuse)^2=(4)^2+(7)^2

(hypotenuse)^2=16+49

(hypotenuse)^2=65

Taking square root both the sides.

hypotenuse=\sqrt{65}

The length of the hypotenuse is √(65) ft . Therefore the correct option is 4.

The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answ
bazaltina [42]

Answer:

The images of the question are missing, I found a matching question and image online, and it is in the attachments.

Answer:

The scale factor of the triangles from the left to the right is 2

or

The scale factor of the triangles from the right to the left is 1/2

Step-by-step explanation:

From the image, the right triangle on the left has the following dimensions:

Hypotenuse = 10

length of one side = 10

While the right triangle on the right has the following:

Hypotenuse = 20

Length of one side = 20

From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:

Left (10)  × 2 = right (20)

Therefore the scale factor of the triangles from the left to the right is 2

or

The scale factor of the triangles from the right to the left is 1/2

Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99​% confidenc
quester [9]

Answer: 18

Step-by-step explanation:

The formula to find the minimum sample size is given by :_

n=(\dfrac{z^*\cdot \sigma}{E})^2

, where \sigma = population standard deviation.

z*= critical z-value.

E= Margin of error.

Given : \sigma= 13

E= ± 8

We know that critical value corresponding to 99% confidence level = z*=2.576  [Using z-table]

Then, the required sample size would be :

n=(\dfrac{(2.576)\cdot (13)}{8})^2

\Rightarrow\ n=(4.186)^2

\Rightarrow\ n=17.522596\approx18 [Round to next integer.]

Hence, the required minimum sample size = 18
