<h3>The hang time for this leap is 0.736 seconds</h3>

<em><u>Solution:</u></em>

<em><u>The vertical leap l measured in feet is related to the hang time t measured in seconds by the equation:</u></em>

L = 4t^2

Where,

L is the vertical leap in feet

t is the hang time in seconds

From given,

L = 2 feet 2 inches

1\ inch = \frac{1}{12}\ feet\\\\2\ inches = \frac{2}{12} = 0.1667\ feet

Therefore,

L = 2 feet + 0.1667 feet = 2.1667 feet

<em><u>Substituting in equation,</u></em>

2.1667 = 4 \times t^2\\\\t^2 = \frac{2.1667}{4}\\\\t^2 = 0.541675\\\\t = 0.73598 \approx 0.736

Thus the hang time for this leap is 0.736 seconds

vladimir2022 [97]

Answer:

Kindly check explanation for (1)

2.)

B. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the power company claim that the mean amount of electricity for their residents is more than the national average.

Step-by-step explanation:

1.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10586 ; population standard deviation, σ = 2509 ; α = 0.05

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10586 - 10290) ÷ (2509/√(153))

296 / 202.84062

Test statistic (Z) = 1.46

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.072

Pvalue > α ; Hence, we fail to reject the Null ; there isn't sufficient evidence to support the power company's claim

2.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10446 ; population standard deviation, σ = 2509 ; α = 0.02

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10446 - 10290) ÷ (2509/√(153))

156 / 202.84062

Test statistic (Z) = 0.769

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.221

Pvalue > α ; Hence, we fail to reject the Null ;

B. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the power company claim that the mean amount of electricity for their residents is more than the national average.

Are the product of 3/4×2/9 greater than 2/9 plz explain
adoni [48]
Less because if you multiply any number by a fraction (not mixed or improper) than it will always be less because multiplying it by 1 will keep it the same anything less than one will make the number smaller the answer of 3/4 x 2/9 is 1/6 btw

Llana [10]

It shows that the values of the mileages are close to 24 mpg. Hence statistics refes 24 as the mean.

<h3>Mean of a data.</h3>

Mean is one of the measure of dispersion and is the avearage of a set of data.

According to the question, the magazine reports that the most common gas mileage was 24 mpg. This shows that reports have published several gas mileages for cars and truck and the average of this mileage is 24mpg

It shows that the values of the mileages are close to 24 mpg. Hence statistics refes 24 as the mean.
