What does this mean?

Mathematics
1 answer:
pychu [463]3 years ago
8 0

Answer:

Step-by-step explanation:

You need to find out if the equation is linear or not. A linear equation will have a constant change. So as x increases by 1, y decreases by 1.25. You would check every line given and see if it continues the same. If so then it is a linear equation. Your slope is the rate of change, meaning how much does x and y increase or decrease. Your b is where the equation starts. You would find b at the top of the table. The first # on this is 0. 8 is your b. x is the input that is  multiplied to the slope to receive the output:y.

pychu [463]

Answer:

30

Step-by-step explanation:

Given :

Mean, m = 30 metric tons

Standard deviation (s) = 1.5 metric ton

Sample size, n = 4

Since the impact force in the test model is normally distributed, the shape of the sampling distribution will also be approximately normal with a mean equal to the mean of the test model.

Hence, the sample mean impact force will be equal to the population mean.

Therefore, sample mean = 30 ; population mean = 30

An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee
fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

  • rate = 25 miles in 40 minute

<h3>Rate</h3>

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

25mi = 40 min\\40 mi = x min

Cross multiply both sides

x * 25 =40 * 40

simplify the value

x*25=40*40\\25x = 1600\\

divide both sides by the coefficient of x

25x = 1600\\25x/25 = 1600/25\\x = 64

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.
