The best prediction for the number of times it will not land on yellow would be 29 times.
We have,
Assuming the spinner has an equal probability of landing on each color, The probability of it not landing on yellow is 4/5.
So,
If you spin the spinner 36 times, the expected number of times it will not land on yellow is:
= (4/5) x 36
= 28.8
Since you can't have a fraction of a spin,
= 28
Thus,
The best prediction for the number of times it will not land on yellow would be 29 times.

Maya just turned 14 years old. Her parents started saving $350 each month for her college.
education when she was born. Her parents want to make sure there will be enough money in
her account by the time she turns 18 to cover tuition and expenses at an in-state, four-year
college. How much will Maya's parents need to raise their monthly contribution for the next 4
years if they want to save at least $80,000?
Answer:
$91.66
Step-by-step explanation:
We need to calculate how much they've saved so far. So we multiply 12 * 14 to get 168 months (14 years). Then we can multiply 350 by 168 to get $58,800.
We then subtract 58,800 from 80,000 to get 21,200 left to cover over 4 years. In 4 years, there are 48 months so we just divide 21,200 by 48 to get 441.66.
Subtract 350 from 441.66 to get 91.66.
We can check this by doing (350*168) + (441.66 * 48).
Hope this helps,
As always, correct me if I'm wrong
Answer:
Given :-
Money saved by her parents each month = $350
Time = 14 years = 14 × 12 = 168 months
To find :-
How much money ger parents have to save in next 4 years to achieve the goal of $80,000
Total money saved in 14 years = 350 × 168 = $58,800
Total money left to achieve goal = 80,000 - 58,800
= $21,200
Money they have saved next 4 years in each month to achieve the goal
[tex] = \frac{21200}{4 \times 12} \\ = \frac{21200}{48} \\ = 441.69 [/tex]
They need $441.69 each month to complete $80,000 for her college.

A researcher conducted a medical study to investigate whether taking a low-dose aspirin reduces the chance of developing colon cancer. As part of the study, 1,000 adult volunteers were randomly assigned to one of the two groups. Half of the volunteers were assigned to the experimental group that took a low-dose aspirin each day, and the other half were assigned to the control group that took a placebo each day. At the end of six years, 15 of the people who took the low-dose aspirin had developed colon cancer and 26 of the people who took the placebo had developed colon cancer. Use a 0. 05 significance level to test the claim that taking a low-dose aspirin each day would reduce the chance of developing colon cancer among all people similar to the volunteers
Using the z-distribution, it is found that there is enough evidence to conclude that taking a low-dose aspirin each day reduces the chance of developing cancer.
What are the hypotheses tested?At the null hypotheses, it is tested if there is no difference among the proportions, that is:
[tex]H_0: p_1 - p_2 = 0[/tex]
At the alternative hypotheses, it is tested if the aspirir proportion is lower, that is:
[tex]H_0: p_1 - p_2 < 0[/tex]
What is the mean and the standard error of the distribution of differences?For each sample, they are given by:
[tex]p_1 = \frac{15}{500} = 0.03, s_1 = \sqrt{\frac{0.03(0.97)}{500}} = 0.0076[/tex]
[tex]p_2 = \frac{26}{500} = 0.052, s_2 = \sqrt{\frac{0.052(0.948)}{500}} = 0.0099[/tex]
Hence, for the distribution of differences, they are given by:
[tex]\overline{p} = p_1 - p_2 = 0.03 - 0.052 = -0.022[/tex]
[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0076^2 + 0.0099^2} = 0.0125[/tex]
What is the test statistic?It is given by:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
In which p = 0 is the value tested at the null hypothesis.
Hence:
[tex]z = \frac{\overline{p} - p}{s}[/tex]
[tex]z = \frac{-0.022 - 0}{0.0125}[/tex]
z = -1.76.
What is the conclusion?Considering a left-tailed test, as we are testing if the proportion is less than a value, the critical value is [tex]z^{\ast} = -1.645[/tex]
Since the test statistic is less than the critical value for the left-tailed test, there is enough evidence to conclude that taking a low-dose aspirin each day reduces the chance of developing cancer.

The circumference of a circle is 12π m. What is the area, in square meters? Express your answer in terms of π.
Answer:
π 36 m^2
Step-by-step explanation:
C = 2π R = 12π m --> R = 6m
A = π R^2 = π 36 m^2
Answer:
Area of circle = 36π m²Step-by-step explanation:
In the question we are given that circumference of circle is 12π m . And we are asked to find the area of circle in term of π .
Solution : -
For finding area of circle we need to find the radius of circle . In the question circumference of circle is given . So we can find radius of circle using it . We know that ,
[tex] \qquad \quad \pink{\underline{\pink{\boxed{\frak{Circumference_ {(Circle) }= 2\pi r}}}}}[/tex]
Where ,
π refers to 3.14 or 22/7r refers to radius of circleBut as in the question , it is given that we have to find the area in term of π. So we aren't using π as 3.14 or 22/7 .
Now, Radius :
[tex] \longrightarrow \qquad \: 12 \cancel{\pi }= 2 \cancel{\pi} r[/tex]
Step 1 : Cancelling π and we get :
[tex] \longrightarrow \qquad \:12 = 2r[/tex]
Step 2 : Dividing both sides by 2 :
[tex] \longrightarrow \qquad \: \cancel{\dfrac{12}{2} } = \dfrac{ \cancel{2}r}{ \cancel2} [/tex]
On further calculations we get :
[tex] \longrightarrow \qquad \: \boxed{ \bf{r = 6 \: m}}[/tex]
Therefore , radius of circle is 6 m .Finding Area :
As we have find the radius of circle above so we can find its area easily . We know that ,
[tex] \qquad \: \qquad \pink{\underline{\pink{ \boxed{{\frak{ Area_{(Circle)} = \: \pi r {}^{2} }}}}}}[/tex]
Now substituting value of radius :
[tex] \longmapsto \: \qquad \quad\pi (6) {}^{2} [/tex]
[tex] \longmapsto \: \qquad \quad \pi \times \: 6 \times 6[/tex]
[tex] \longmapsto \: \qquad \quad \pi \times 36[/tex]
We get :
[tex] \longmapsto \: \qquad \quad \blue{\underline{\blue{\boxed{\frak{ \bf{36 \pi \: m {}^{2} }}}}}}[/tex]
Therefore, area of circle is 36π square metres .#Keep Learningplease What is worse Precalculus or AP Computer Science Principles?? I have to decide which class i want. PLEASE ANSWER QUICK

For me, the easiest thing to do we would be to add a half hour (30 minutes) to the 8:45. This gets 9:15. Since 9:15 is past 9:10, I subtract the difference to get 5 minutes. I then take the 30 minutes I added to the 8:45 and subtract the 5 minutes that it went over to get 25 minutes. This is the easiest way to get the answer in my opinion.
