2. if the cost of 10 gallons of gasoline is 30 dollars then divide 10 by 10 and divide 30 by 10 to get 1 and 3 so the cost of 1 gallon is $3
3. if 2 packets of bread is 3 dollars then divide 2 and 3 by 2 so in conclusion 1 loaf f bread is $1.50.
4. if a cleaning service charges $1000 for 20 offices then divide 1000 by 20 and 20 by 20 to have an answer of $50 for every one office.
5. to find the answer to this problem you need to divide 320 by 4 to find out organes per bag so 80 oranges per bag.
6. if the baker ca bake 12 cakes every 45 minutes then he can bake 4 cakes every 15 minutes because divide both 12 and 45 by three so in conclusion the baker can bake 16 cakes every hour.
7. so if you can print 100 pages for $2 then multiply 100 and 2 by two to get 200 pages for $4
8. so to find the answer to this all you need to do is divide 12 by six to fin out that it is 2 apples for $1 and for the other store you divide 21 by seven to find out that it is 3 apples for $1.
9. to find out the answer for this divide 24,000 by 12 to find that his monthly income is $2,000.
10. if a 0.2 pund package is $4 then a 0.001 pound package is 20 cents.
I hope i got the answers right and that i could help! :)
Answer:
A
Step-by-step explanation:
Answer:
92.9997<
<99.5203
Step-by-step explanation:
Using the formula for calculating the confidence interval expressed as:
CI = xbar ± Z * S/√n where;
xbar is the sample mean
Z is the z-score at 90% confidence interval
S is the sample standard deviation
n is the sample size
Given parameters
xbar = 96.52
Z at 90% CI = 1.645
S = 10.70.
n = 25
Required
90% confidence interval for the population mean using the sample data.
Substituting the given parameters into the formula, we will have;
CI = 96.52 ± (1.645 * 10.70/√25)
CI = 96.52 ± (1.645 * 10.70/5)
CI = 96.52 ± (1.645 * 2.14)
CI = 96.52 ± (3.5203)
CI = (96.52-3.5203, 96.52+3.5203)
CI = (92.9997, 99.5203)
<em>Hence a 90% confidence interval for the population mean using this sample data is 92.9997<</em><em><99.5203</em>
Answer:
-2 1/5, -1 2/5, 1/5, |-3/5|, |-1 1/5| ,|-2 2/5|
Step-by-step explanation:
Absolute value means take the positive value
-2 1/5
|-1 1/5| = 1 1/5
|-2 2/5| = 2 2/5
1/5
|-3/5| = 3/5
-1 2/5
We want the numbers from smallest to largest
The most negative is
-2 1/5, -1 2/5
Then to the fractions
1/5, |-3/5|
Then the positive numbers
|-1 1/5| ,|-2 2/5|
