Alexandra [31]

Answer:

\large\boxed{C=2\pi r}

Step-by-step explanation:

A linear equation is an equation in which a variable is in the first power.

The formula of a Circumference of a circle

C=2\pi r\\\\2,\ \pi-\text{numbers}\\r-\text{variable}\\\\\boxed{\bold{YES}}

The formula of an Area of a circle

A=\pi r^2\\\\\pi-\text{number}\\r^2-\text{variable in the second power}\\\\\boxed{\bold{NO}}

The formula of a volume of a sphere

V=\dfrac{4}{3}\pi r^3\\\\\dfrac{4}{3},\ \pi-\text{numbers}\\r^3-\text{variable in the third power}\\\\\boxed{\bold{NO}}

For each of the following situations, state whether the appropriate test would be a Independent Samples T test or Paired T Test,
Anvisha [2.4K]

Answer:

B. Paired T Test

B. H0: μd = 0 and Ha: μd < 0 where μd= mean difference in blood pressure (calculated as aspirin - placebo)

Step-by-step explanation:

As the experiment is based on the difference between the results of a pair, the most appropiate test is a paired t-test.

If the 80 people group had been dividided in 2 and then compare the means for each group, it would have been a independent samples t-test.

For each pair, a variable d (for difference) is calculated and used as the outcome sample to perform the test.

Then, the null hypothesis will state that the population mean for this difference is not significantly different from 0, and the alternative hypothesis claiming it is signficant different from 0.

The sample means for the treatment group and the placebo is not individually calculated, as only the difference for each pair is used as sample in a paired t-test.

The perimeter is= sum of sides  

                           = 10+10+12 \\\\                =32 \ units\\\\

Calculating the Area of base= \frac{1}{2} \times base \times height

                                               = \frac{1}{2} \times 12 \times 8\\\\= \frac{1}{2} \times 96\\\\=48 \ units^2
