Is the mean age at which American children learn to walk less than 15 months? A study of 40 American children found a mean walki
Sonbull [250]

Answer:

We define the random variable X as the walking age and we are interested if American children learn to walk less than 15 months so then that would be the alternative hypothesis and the complement would be the null hypothesis.

Null hypothesis: \mu \geq 15

Alternative hypothesis: \mu

And for this case the best answer would be:

H 0 : μ ≥ 15 vs. Ha : μ < 15

Step-by-step explanation:

We define the random variable X as the walking age and we are interested if American children learn to walk less than 15 months so then that would be the alternative hypothesis and the complement would be the null hypothesis.

Null hypothesis: \mu \geq 15

Alternative hypothesis: \mu

And for this case the best answer would be:

H 0 : μ ≥ 15 vs. Ha : μ < 15

And the data given from the sample is:

\bar X = 13.2 represent the sample mean

\sigma represent the population deviation

n = 40 represent the sample size

And the statistic would be given by:

z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

Find the area of each shape. Show your reasoning.
Troyanec [42]

Answer:

Those areas are: A 1 = 12,  A 2 = 19

Step-by-step explanation:

The area of shape 1  : it consists of 1 square + 4 right triangles

Area of the square: A = a², area of the triangle: A = 1/2 · a · h

A 1 = 2² + 4 · 1/2 · 2 · 2 = 4 + 8 = 12

The area of shape 2 :  it consists of 2  isosceles triangles

A 2 = 1/2 · 2 · 4 + 1/2 · 6 · 5 = 4 + 15 = 19

A square patio has an area of 200 square feet. How long is each side of the patio to the nearest tenth?
Darya [45]
If patio is square it means that area of if is A=a^2 where a is one side
Now we can substitute A=200 and solve eq
a^2=200
a=\sqrt{200}
a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1
