kong: 15% 15x100=1,500

Nolan:85 seconds 85x2=170

then when you multiple kong by 15 and 100 it gives you 1,500 however nolan did of the seconds 85x 2 gives you 170 . in conclusion Nolan did 15x2=30 . which means Nolan did 30 seconds.

Let us suppose that (28 , 32) inches is an 80% one-sample confidence interval for the average height of all adult miniature hors

vlada-n [284]

Answer:

Yes, because 29.5 lies within the interval.

Step-by-step explanation:

Since the given interval of (28, 32) inches has an 80% confidence level. It is plausible to estimate with 80% certainty that the mean height of all adult miniature horses falls within that interval.

A height of 29.5 belongs to the interval:

28≤ 29.5 ≤ 32

Therefore, based on the confidence interval, the belief that the population average height is 29.5 inches is plausible

Point M is the midpoint of segment AC. Point M is located at (25.5, 60.1) and point C is located at (18.3, 72.5). What is the lo

Strike441 [17]

Answer:

$A = (32.7,47.7)$

Step-by-step explanation:

Given

$M = (25.5,60.1)$

$C = (18.3,72.5)$

Required

Determine the coordinates of A

Midpoint is calculated as thus:

$M(x,y) = (\frac{A_x + C_x}{2}, \frac{A_y + C_y}{2})$

Substitute the given values

$(25.5,60.1) = (\frac{A_x + 18.3}{2}, \frac{A_y + 72.5}{2})$

Multiply through by 2

$2 * (25.5,60.1) = (\frac{A_x + 18.3}{2}, \frac{A_y + 72.5}{2}) * 2$

$2 * (25.5,60.1) = (A_x + 18.3, A_y + 72.5)$

$(51,120.2) = (A_x + 18.3, A_y + 72.5)$

By comparison:

$A_x + 18.3 = 51$

$A_y + 72.5 = 120.2$

$A_x + 18.3 = 51$

$A_x = 51 - 18.3$

$A_x = 32.7$

$A_y + 72.5 = 120.2$

$A_y = 120.2 - 72.5$

$A_y = 47.7$

Hence:

$A = (32.7,47.7)$

Solve for x: 5x+7=3x−9.

ludmilkaskok [199]

To solve for x in the given equation;

$5x+7=3x-9$

We start by collecting like terms, as follows;

$5x-3x=-9-7$

When a number crosses the sign of equality, the sign in front of it switches. Positive numbers becomes negative, and vice versa.

We would now have;

$\begin{gathered} 5x-3x=-9-7 \\ 2x=-16 \\ \text{Divide both sides by 2;} \\ \frac{2x}{2}=\frac{-16}{2} \\ x=-8 \end{gathered}$

ANSWER:

The answer is x = -8

Why is estimation useful when finding actual products and solving real-world problems?

It's Cause We Study Real-World-Problems Without Education We wouldn't learn anything so its good to study independently so our brains can grow!
