Answer:
x = 4 (ONE solution)
Step-by-step explanation:
This is a first order linear equation, so we can expect 1 solution.
Multiplying out the left side, we get:
8x - 24 = 7x - 20, which simplifies to:
x = 4 (ONE solution)
Step-by-step explanation:
Following the order of operations we would first divide -30 by 5 which would give us -6
-6 + (-30) ÷ 5 - (-2)
From here we can add -6 + -6 = -12
-6 + (-6) - (-2)
When subtracting a negative number, the two negatives changes it to a positive. (-12) - (-2) = (-12) + 2 which would give us -10
(-12) - (-2) = -10

To solve the problem we must know about the correlation coefficients.
<h3>What is the
correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
Given to us
- The correlation coefficient for the data is −0. 9847.
As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.
Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".

Answer:
The mouse ran the race at an average of 1.12 miles per hour.
Step-by-step explanation:
In order to find this, we need to convert the seconds into hours and the centimeters into miles. To do this, we divide by the unit rates.
7 secs / 3600 seconds per hour = .00194 hours
350 cm / 160934 cm per mile = .00217 miles
Now we divide the total number of miles by the total number of hours to get the speed.
.00217 miles / .00194 hours = 1.12 mph
