Answer:

Step-by-step explanation:

hi! let's divide -24 and -6 to simplify this. this is the same answer as 24/6 since two negatives that are divided by each other equal a positive number, and 24 divided by 6 is 4, so the answer is 4.

A national random sample of 654 women aged 20 – 29 years was taken, and each woman's body mass index (BMI) was measured. The sam

Answer:

The required interval is (26.23 , 27.37)

Step-by-step explanation:

The mean is = 26.8

The standard deviation is = 7.42

n = 654

At 95% confidence interval, the z score is 1.96

To find the desired interval we will calculate as:

$26.8+1.96(\frac{7.42}{\sqrt{654} } )$

And $26.8-1.96(\frac{7.42}{\sqrt{654} } )$

$26.8+0.57$ and $26.8-0.57$

= 27.37 and 26.23

So, the required interval is (26.23 , 27.37)

When the exponent blank is applied to a nonzero base, the result is always 1

boyakko [2]

Answer:

zero (0)

when the exponent 0 is applied to a nonzero base, the result is always 1

Step-by-step explanation:

Acoording to the zero power rule, a non zero number raised to the power 0 is always 1:

$a^{0} =1$ whit $a=0$

Let's check this property using an example:

We know that a quantity over itself is always 1: $\frac{2}{2} =1$

We also know that a base without exponent is always raised to the power 1: $2=2^{1}$

Now, according to the division power rule $\frac{a^{m} }{a^{n}} =a^{m-n}$ , so $\frac{2}{2} =\frac{2^{1} }{2^{1} } =2^{1-1} =2^{0} =1$

Each unit in the coordinate plane corresponds to 1 mile. Find the distance from the school to Cherry Street. Round your answer t

GarryVolchara [31]

Answer:

$11.2$

Step-by-step explanation:

We can use the distance formula to solve this problem.

This distance formula states that the distance between two points $(x_1, y_1)$ and $(x_2,y_2)$ is equal to $\sqrt{(\Delta x)^2+(\Delta y)^2}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

School is at coordinate point (9,6) and the closest point to school on Cherry St. is (4,-4).

Thus, the distance between school and Cherry Street is $\sqrt{(9-4)^2+(6-(-4))^2}=\sqrt{5^2+10^2}=\sqrt{125}=5\sqrt{5}\approx \boxed{11.2}$
