Answer:

12x +9y ≥ 510
y ≤ 2x
y ≥ 25

Step-by-step explanation:

Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...

12x +9y ≥ 510

Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...

y ≤ 2x

Richie will walk at least 25 dogs, so ...

y ≥ 25

A researcher determines that students are active about 60 + 12 (M + SD) minutes per day. Assuming these data are normally distri

rjkz [21]

Answer:

The correct option is (b).

Step-by-step explanation:

If X $\sim$ N (µ, σ²), then $Z=\frac{X-\mu}{\sigma}$ , is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z $\sim$ N (0, 1).

The distribution of these z-variate is known as the standard normal distribution.

The mean and standard deviation of the active minutes of students is:

μ = 60 minutes

σ = 12 minutes

Compute the z-score for the student being active 48 minutes as follows:

$Z=\frac{X-\mu}{\sigma}=\frac{48-60}{12}=\frac{-12}{12}=-1.0$

Thus, the z-score for the student being active 48 minutes is -1.0.

The correct option is (b).

108x25^2divided by 2^6 x 5^2

My name is Ann [436]

Answer:

108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$

Step-by-step explanation:

Given;

108 x 25² divided by 2⁶ x 5²

The expression is simplified as follows;

$\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}$

Therefore, 108 x 25² divided by 2⁶ x 5² is equal to $42\frac{3}{16}$
