Answer:
9/12
Step-by-step explanation:
First you multiply 3x12 which equal 36 then you divide 36 by 4 which equal 9 so your answer is 9/12
Answer:
21.45 miles
Step-by-step explanation:
Key:
t=time
d=distance
We need to find the time the lion ran first.
The time the lion ran:
13.75=50•t
13.75=50t
-50t=-13.75
t=-13.75•-1/50
t = 0.275
So the lion ran in 13.75 miles in 0.275 of an hour.
Now, we need to figure out the cheetah.
0.275•78=21.45 miles
I hope this helps :-)
Answer:
x+3. is the first num
x +4 is the second num
the sum is 2x +7
Answer:
2x + 7
Difference is 1
Step-by-step explanation:
Consecutive numbers are numbers that increase with a steady difference.
For example; 1, 2, 3 all increase with a difference of 1 (2 = 1 + 1; 3 = 2 + 1) and so on.
If the smaller of two consecutive numbers is x + 3, that means the other number which should be bigger is x + 4
Therefore the sum of both numbers is (x + 3) + (x + 4) = 2x + 7.
Their difference is (x + 4) - (x + 3) = 1
And subtracting their sum from x + 8 gives (x + 8) - (2x + 7) = x + 8 - 2x - 7 = -x + 1.
Answer:
The error bound is 3.125%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
A sample of 506 California adults.. This means that .
76% of California adults (385 out of 506 surveyed) feel that education is one of the top issues facing California. This means that
We wish to construct a 90% confidence interval
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The error bound of the confidence interval is the division by 2 of the subtraction of the upper limit by the lower limit. So:
The error bound is 3.125%.

Answer:
If a regular year, about 158,904. If a leap year, about 158,469
Step-by-step explanation:
for a regular year, 58,000,000 divided by 365 = 158,904
for a leap year, 58,000,000 divided by 366 = 158,469
Answer: 158,904
Step-by-step explanation:
58,000,000/365=158,904.10958904 which rounded is 158,904
Answer:
No
Step-by-step explanation:
substitute -2 for 'x' and 5 for 'y'
2(-2) + 5(5) = 0?
-4 + 25 = 21, not 0
