Bas_tet [7]2 years ago
3 0

Given:

3,6,9,12,15,18...

We need to find the difference.

The difference between 3 and 6 is 6-3 =3.

The difference between 6 and 9 is 9-6 =3.

The difference between 9 and 12 is 12-9 =3.

The difference between 12 and 15 is 15-12 =3.

The difference between 15 and 18 is 18-15 =3.

Recall that linear have equal differences.

We get an equal difference between each value.

The form of the equation is

y=3x

Hence the given is linear.

The body temperatures of a group of healthy adults have a​ bell-shaped distribution with a mean of 98.18 F and a standard deviat
S_A_V [24]

Answer:

99.7%

Step-by-step explanation:

Empirical rule formula states that:

• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question, we have mean of 98.18 F and a standard deviation of 0.65 F

The approximate percentage of healthy adults with body temperatures between 96.23 F and100.13 ​F is

μ - 3σ

= 98.18 - 3(0.65)

= 98.18 - 1.95

= 96.23 F

μ + 3σ.

98.18 + 3(0.65)

= 98.18 + 1.95

= 100.13 F

Therefore, the approximate percentage of healthy adults with body temperatures between 96.23 F and 100.13 ​F which is within 3 standard deviations of the mean is 99.7%

The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r? l/pt=r pt/l=r l-pt=r l+pt
Nadya [2.5K]

I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing.

I = PRT

I / P = RT to divide both sides by P

I / PT = R to divide both sides by T

So I / PT = R (the first choice) is the equation solved for R.
