5 A box of donuts holds
12 donuts. One-fourth
of the donuts have
sprinkles. Of the remaining
donuts, one-third have
cherry filling. The rest are
plain, What percent of the
donuts are plain?
Answer:
91.6667%
Step-by-step explanation:
1/3 of 1/4 = 1/12
11/12 = 91.6667%
Have a great day <3
Answer:
50% of the donuts are plain
Step-by-step explanation:
out of 12 donuts, 1/4 have sprinkles. This results in 3 donuts having sprinkles. 3 out of 12 is 9. 1/3 of 9 is 3. 3 donuts have cherry filling. The rest, which is 6 are plain. 6 is 50% of 12.
If one-fourth of 2^30 is equal to 2^x, what is x?
Answer:
28
Step-by-step explanation:
1/4 can be rewritten as 1 / (2^2)
or 2^-2.
using the 2nd form,
we have 2^-2 * 2^30 = 2^x
By exponent rule
2^28 = 2^x
So we can observe now that x = 28

From among the 300 largest cities in the United States, the FleeceU Auto Insurance Company identified the 10 safest and 10 least-safe U.S. cities based on the mean number of years drivers went between automobile accidents. The cities on both lists were the smaller cities on the list of the 300 largest.

Cities in which the mean is based on a smaller number of drivers will have greater variation in their means and are therefore more likely to be both safest and least safe.
What is random sampling?In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.
Given that, from among the 300 largest cities in the United States, the FleeceU Auto Insurance Company identified the 10 safest and 10 least-safe U.S. cities.
It is noted that mean is used to measure the safety of a city. It is known that outliers have more effect on the mean value. The outlier drags the center or mean value toward it. Also, small samples usually have more variation. This could be the reason why small cities are on both safe and least safe cities lists.
So, the correct option is d.
Options (a) and (c) do not include any interpretation in terms of mean. Option (b) suggests that data is bimodal, but it does not signify why small cities are more in the lists. Option (e) does not conclude in terms of mean. Option (f) suggests the phenomenon of traffic congestion in big cities, but it cannot be considered only because of traffic the mean year is less. Option (g) does not imply statistically meaningful evidence to suggest the claim. And, option (h) is almost the same as option (d). However, since it does not suggest more about the variation, it is incorrect. Thus, except option (d), the remaining all statements are not recommended.
Therefore, option D is the correct answer

From among the 300 largest cities in the United States, FleeceU Insurance Company identified the 10 safest and 10 least-safe U.S. cities based on the mean number of years drivers went between automobile accidents. The cities on both lists were the smaller cities on the list of the 300 largest. Use facts about the sampling distribution model of the sample mean to select the choice below that explains why this is not surprising.
a. More people in larger cities drive older cars that are more accident prone.
b. In smaller cities, the distribution of the mean number of years drivers go between accidents is bimodal, which makes it more likely they will be in the safest and least-safe cities.
c. Larger cities have a higher incidence of hit-and-run accidents.
d.Cities in which the mean is based on a smaller number of drivers will have greater variation in their means and are therefore more likely to be both safest and least safe.
e. Accident statistics are more accurate in smaller cities.
f. Traffic congestion in larger cities decreases the mean number of years drivers go between accidents but not enough to place larger cities In the least-safe group.
g.Large cities are not on the safest list because their mean time between accidents is reduced by people who "stage" accidents for purposes of insurance fraud.
h.Smaller cities are safer, but a few accident-prone drivers (outliers) in some small cities decreases the mean number of years between accidents, resulting in these cities being listed on the least-safe list.

Doug took 180 photos during his vacation. He took 2/3 of photos during
the first day of his vacation. Of those photos, ¼ were of landscapes and
0.3 were of people. How many photos were of landscapes and people?
Answer:
66 pictures
Step-by-step explanation:
180 ÷ 3 = 60 60 x 2 = 120
120 = 2/3. He took 120 pictures on the first day of his vacation.
120 ÷ 4 = 30 30 x 1 = 30
30 = 1/4. He took 30 pictures of landscapes
120 ÷ 10 = 12 12 x 3 = 36
0.3 = 36. He took 36 pictures of people.
36 + 30 = 66 pictures.
He took 66 pictures of landscapes and people.

WORTH 35 POINTS!!! Annie’s dad travels for business. On Monday, he drives for 4 hr. at a constant rate of 55 mph to meet with a customer. On Tuesday, he drives 3 hr. at a constant rate of 50 mph to meet with his district sales manager. On Wednesday, he drives 2 hr. at a constant rate of 60 mph to pick up supplies at the warehouse. How many miles does Annie’s dad drive total before he heads for home?
A. 120 mi.
B. 150 mi.
C. 220 mi.
D. 490 mi.
Answer:
220mi
Step-by-step explanation:
Annie's dad drove a total of 490 miles before heading home. The correct option is D.
What is the distance?Distance is defined as the product of speed and time.
We can use the formula distance = rate x time to calculate the distance for each day.
On Monday, he drove for 4 hours at 55 mph, so the distance he traveled was:
distance = 55 mph x 4 hours = 220 miles
On Tuesday, he drove for 3 hours at 50 mph, so the distance he traveled was:
distance = 50 mph x 3 hours = 150 miles
On Wednesday, he drove for 2 hours at 60 mph, so the distance he traveled was:
distance = 60 mph x 2 hours = 120 miles
To find the total distance, we can add up the distances for each day:
220 miles + 150 miles + 120 miles = 490 miles
Therefore, Annie's dad drove a total of 490 miles before heading home.

reflection
vertical translation up 2
vertical translation down 3
vertical translation up 3
horizontal translation left 3
horizontal translation right 2
horizontal translation left 2
compression by a factor of 3
stretch by a factor of 2
Answer:
reflection
vertical translation down 3
horizontal translation right 2
Step-by-step explanation:
Given
[tex]y = x^2[/tex] ---> Parent function
[tex]y = -(x+2)^2-3[/tex]
Required
All possible transformations
First, the parent function is reflected across the x-axis:
This gives:
[tex]y = x^2[/tex] [tex]==>[/tex] [tex]y =-x^2[/tex]
Next, it is translated horizontally right by 2
The rule is:
[tex](x,y)==>(x+2,y)[/tex]
So:
[tex]y =-x^2[/tex] [tex]==>[/tex] [tex]y = -(x +2)^2[/tex]
Lastly: it is translated vertically down by 3
The rule is:
[tex](x,y)==>(x,y-3)[/tex]
So:
[tex]y = -(x +2)^2[/tex] [tex]==>[/tex] [tex]y = -(x +2)^2 - 3[/tex]
