The mean of 5 numbers is 14. If the first four numbers in the data set are 12, 17, 24, and

NISA [10]

Answer:

a. x + 64 = 70

b. x = 6

Step-by-step explanation:

Let the fifth number be x.

$\implies \: mean = \frac{sum \: of \: the \: numbers}{total \: numbers} \\ \\ \implies \: 14 = \frac{12 + 17 + 24 + 11 + x}{5} \\ \\ \implies \: 14 = \frac{64 + x}{5} \\ \\ \implies \: 14 \times 5 =x+ 64 \\ \\\implies \:\purple{\bold{x+ 64 =70}}\\(this \: is \:the \: required\: equation)\\ \\ \implies \: x= 70 - 64 \\ \\ \implies \: x = 6$

Find the equation in standard form of the line parallel to y=-1/5x+7 and passing through the point (-10,-3)

Softa [21]

Answer:

the desired equation is y = (-1/5)x - 5.

Step-by-step explanation:

Parallel lines have the same slope. Here that slope is -1/5.

Let's use the slope-intercept form of the equation of a straight line:

y = mx + b

We know this new line passes through (-10, -3). Substitute -3 for y in y = mx + b, as well as -10 for x and -1/5 for m:

-3 = (-1/5)(-10) + b and solve for b:

-3 = 2 + b. Then b = -5, and the desired equation is y = (-1/5)x - 5.
