Answer:
The 2 above the 10 is called a power. It means 10 times itself twice. So 10 times 10 is 100. 3050/100=30.5
Step-by-step explanation:
Answer:
C = 20
Step-by-step explanation:
What happens if simultaneous Equations have two of the same variable like below? How would I solve it?
6A + 4B + 5C = 390
6A + 4B + 5.75C = 405
Step 1
We solve for C first
6A + 4B + 5C = 390....Equation 1
6A + 4B + 5.75C = 405... Equation 2
We substract Equation 1 from Equation 2
0.75C = 15
C = 15/0.75
C = 20
ANSWER: Paige's unit rate for filling the bucket, in gallons per minute (gpm) is 1.5
EXPLANATION: Based on the given fractions, we need to divide 3/8 by 1/4. Divide by its reciprocal: 3/8 * 4. Cross out the common factor, 3/2. Then, obtain the result, 1.5 GPM.
Answer:
c.145.3 to 154.7.
Step-by-step explanation:
We have to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a p-value of , so Z = 1.645.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 150 - 4.7 = 145.3.
The upper end of the interval is the sample mean added to M. So it is 150 + 4.7 = 154.7.
Thus the correct answer is given by option c.
