-BARSIC- [3]

Answer: Destiny's speed is 11 mph.

Alicia's speed is 15 mph

Step-by-step explanation:

Destiny and Alicia both leave the coffee shop at the same time, but in opposite directions. If they are 78 miles apart after 3 hours, it means that the total distance that they covered in 3hours is 78 miles

Let x represent the speed at which Destiny travelled. If Alicia travels 4 mph faster than Destiny, it means that the speed at which Alicia travelled is (x + 4) mph

Distance = speed × time

Distance covered by Destiny in 3 hours is

3 × x = 3x

Distance covered by Alicia in 3 hours is

3(x + 4) = 3x + 12

Since the total distance is 78 miles, then

3x + 3x + 12 = 78

6x = 78 - 12 = 66

x = 66/6 = 11 mph

Alicia's speed is

11 + 4 = 15 mph

A survey shows that 45% of the respondents pick option A. Given that 50 people replied, what is the standard error of the propor
QveST [7]
The formula for the standard error is this:
σM = σ / √N

where
σM is the standard error
σ is the standard deviation
N is the number of samples

So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%

The standard error is 0.0636

What is the constant of proportionality of y to x?
AleksAgata [21]

<u>Answer:</u>

2.5

<u>Step-by-step explanation:</u>

We are given a graph with a positive slope where the value of y increases when the value of x increases.

For the given graph, we are to find the constant of proportionality of y to x which is the slope of the given line.

We know the formula of the slope = \frac{y_2-y_1} {x_2-x_1}

Substituting the given values in the formula:

\frac{15-10}{6-4} = \frac{5}{2} = 2.5
