Fudgin [204]

Answer:

2.51 < σ < 3.92

Step-by-step explanation:

We will use Chi-Square distribution to create the interval. We have the following information:

n = 41

Level of Confidence : 95%,

This corresponds to Chi-Square values of:

24.433 for the left tail and 59.342 for the right tail

We need to calculate the sample Variance. This is done on attached photo 1 (the shortcut formula for finding variance was used)

We get s = 9.3866.

See the construction of the confidence interval on the second attached photo

Ana’s gymnastics scores were posted on the scoreboard in order from highest to lowest score. One digit in her floor score is not

BabaBlast [244]

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

Step-by-step explanation:

The floor score must be higher than 15.133 and lower than 15.500

The missing digit must be an integer.

Then all the possible scores are: 15.166 , 15.266 , 15.366 and 15.466

Then all the possible digits are 1 , 2 , 3 and 4

The difference between her vault score and her uneven bar score is

15.500 - 15.133 = 0.367

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

I have one more question before im done so please help and have a good day.

3241004551 [841]

Answer:

See below

Step-by-step explanation:

<u>Solve the equation:</u>

6x² + 48x + 120 = 0
x² + 8x + 20 = 0
x² + 8x + 16 + 4 = 0
(x + 4)² + 4 = 0
(x + 4)² = - 4

The left side is positive and right side is negative so no solution

There is no intercession with the x-axis, the graph of the function is entirely above the x-axis.

It means the diver won't reach the bottom of the lake

Q # 9 please find the area

Rudik [331]

To solve this problem you must apply the formula for calculate the surface area of a circle, which is shown below:
SA=πir^2
where r is the radius of the circle
r=18 inches
By substituying values, you have that the surface area is:
SA=π(18 in)^2
SA=324π in^2
The answer is 324π in^2
