<span>As we know that in an hour there are 3600 seconds so
1.8 x 3600 = 6480
 6480 / 1609 = 4.02 miles / hr
   4.02 - 2.5 = 1.5( by substracting the speed)
so correct option is D which is

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Rate at which Alina swim = 2.5 miles per hour

Rate at which Talia swim = 1.8 meters per second

First we need to change meters per second into miles per hour

As we have given that

1\text{ miles}=1609\text{ meters}

and

1\text{ hour}=3600\text{ seconds}

So, to change into miles per hours, we'll apply this,

\frac{1.8\times 3600}{1609}\\\\=4.02\text{ miles per hour}

So,

Difference between their rates will be given by

4.02-2.5=1.52\text{ miles per hour}

Hence, Talia swims about 1.5 miles per hour faster than Alina.

So, Option 'D' is correct.

Part A: Which three-dimensional geometric shape best models this pancake? (1 point)
barxatty [35]

Answer:

Step-by-step explanation:

Part A: The pancake is a cylinder shape with a circular top and bottom and straight middle.

Part B: Rotating a circle will NOT make a cylinder. Instead rotating a rectangular around a vertical axis will. It is a rectangle of 1cm height and 7cm length rotating around an axis at its edge.**

**Thanks to Moderator wegnerkolmp2741o who pointed out that it has to be a rectangle of 1cm height and 7cm length rotating around an axis at its edge. My original option of 1cm height and 14cm length rotating around its center would cause an overlapping shape.

A laptop producing company also produces laptop batteries, and claims that the batteries
gregori [183]

Answer:

There is enough evidence to support the claim that the batteries power the laptops for significantly less than 4 hours. (P-value = 0).

The null and alternative hypothesis are:

H_0: \mu=4\\\\H_a:\mu< 4

Step-by-step explanation:

<em>The question is incomplete: To test this claim a sample or population standard deviation is needed.</em>

<em>We will estimate that the sample standard deviation is 2 hours, and use a t-test to test that claim.</em>

<em> NOTE (after solving): The difference between the sample mean and the mean of the null hypothesis is big enough to reject the null hypothesis, even when we have a sample standard deviation of 3.5 hours, which can be considered bigger than the maximum standard deviation for the sample.</em>

This is a hypothesis test for the population mean.

The claim is that the batteries power the laptops for significantly less than 4 hours.

Then, the null and alternative hypothesis are:

H_0: \mu=4\\\\H_a:\mu< 4

The significance level is 0.05.

The sample has a size n=500.

The sample mean is M=3.5.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=2.

The estimated standard error of the mean is computed using the formula:

s_M=\dfrac{s}{\sqrt{n}}=\dfrac{2}{\sqrt{500}}=0.0894

Then, we can calculate the t-statistic as:

t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{3.5-4}{0.0894}=\dfrac{-0.5}{0.0894}=-5.5902

The degrees of freedom for this sample size are:

df=n-1=500-1=499

This test is a left-tailed test, with 499 degrees of freedom and t=-5.5902, so the P-value for this test is calculated as (using a t-table):

P-value=P(t

As the P-value (0) is smaller than the significance level (0.05), the effect is  significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that the batteries power the laptops for significantly less than 4 hours.

Aleks04 [339]

Answer:

A) True , B) True , C) False

Step-by-step explanation:

A) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.

B) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.

C) False : Null Hypothesis can be accepted, despite of being actually false. This is called Type 2 Error.

Rent during the 8th year is $3072

Step-by-step explanation:

  • Step 1: Rent of the apartment = $1600 Given, the rent will go up by 11.5%

⇒ 11.5% of the rent = 11.5/100 × 1600 = $184

  • Step 2: Calculate the rise in rent for 8 years

⇒ 184 × 8 = $1472

  • Step 3: Calculate the rent during the 8th year

⇒ 1600 + 1472 = $3072
