Survey was conducted to determine the food choices of the 80 students at a bicnic. The types of picnic foods are shown in the circle graph Picnic Food Salad 10% Sandwich 20% Hamburger 15% Hot dog 25% Pizza 30%
Answers
Answer:
16
Step-by-step explanation:
The number of more students who choose pizza rather than students who choose salad is 16.
It is given that
total number of students=80
what is the percentage?It is value per hundred.
number of students who choose salad= 10% of 80=8
number of students who choose Sandwich=20% of 80=16
number of students who choose Hamburger = 15% of 80 = 12
number of students who choose Hot Dog=25% of 80 = 20
number of students who choose Pizza = 30% of 80 = 24
so,
Number of more students who choose pizza rather than students who choose salad = Number of students who choose pizza - Number of students who choose Salad = 24-8 =16
Therefore,
the number of more students who choose pizza rather than students who choose salad is 16.

y=2x/3-2 is the required slope-intercept form of the line
The coordinate of points where the line intersects at the x-axis is (-3,0) and at the y-axis is (0,-2) now from there two points we can find slope if line that is
slope=y₂-y₁/x₂-x₁=(-2-0)/(0-(-3))
slope =-2/3
with one point (0,-2) and slope we can find the slope-intercept form that is y=mx+c

shift worker clocks in at 1730 hours and clocks out at 0330 hours.
How long was the shift?
Answers
To calculate the duration of the shift, you need to subtract the clock-in time from the clock-out time.
In this case, the shift worker clocked in at 1730 hours (5:30 PM) and clocked out at 0330 hours (3:30 AM). However, since the clock is based on a 24-hour format, it's necessary to consider that the clock-out time of 0330 hours actually refers to the next day.
To calculate the duration of the shift, you can perform the following steps:
1. Calculate the duration until midnight (0000 hours) on the same day:
- The time between 1730 hours and 0000 hours is 6 hours and 30 minutes (1730 - 0000 = 6:30 PM to 12:00 AM).
2. Calculate the duration from midnight (0000 hours) to the clock-out time:
- The time between 0000 hours and 0330 hours is 3 hours and 30 minutes (12:00 AM to 3:30 AM).
3. Add the durations from step 1 and step 2 to find the total duration of the shift:
- 6 hours and 30 minutes + 3 hours and 30 minutes = 10 hours.
Therefore, the duration of the shift was 10 hours.

Answers
We can make a drawing to see better:
7) We know that RM = 4 and MS = 9, so:
\(\begin{gathered} \tan a=\frac{MS}{RM}=\frac{TM}{MS} \\ TM=\frac{MS^2}{RM}=\frac{9^2}{4}=\frac{81}{4}=20.25 \end{gathered}\)The answer is TM = 20.25
8) We know that RS = 20 and RM = 8, so:
\(\begin{gathered} \sin b=\frac{RM}{RS}=\frac{RS}{RT} \\ RT=\frac{RS^2}{RM}=\frac{20^2}{8}=\frac{400}{8}=50 \end{gathered}\)The answer is RT = 50.
9) We know that RM = 5 and MS = 7, so:
\(\begin{gathered} \tan b=\frac{RM}{MS}=\frac{RS}{TS} \\ TS=RS\cdot\frac{MS}{RM} \\ RS=\sqrt[]{RM^2+MS^2} \\ TS=\sqrt[]{RM^2+MS^2}\cdot\frac{MS}{RM} \\ TS=\sqrt[]{5^2+7^2}\cdot\frac{7}{5}=\sqrt[]{25+49}\cdot\frac{7}{5} \\ TS=\sqrt[]{74}\cdot\frac{7}{5}\approx12.043 \end{gathered}\)The answer is TS = 12.043
10) We know that RM = 1/2 and MS = 1/4, so:
\(\begin{gathered} \sin b=\frac{RM}{RS}=\frac{RS}{RT} \\ RT=\frac{RS^2}{RM}=\frac{RM^2+MS^2}{RM} \\ RT=\frac{(\frac{1}{2})^2+(\frac{1}{4})^2}{\frac{1}{2}}=2\cdot(\frac{1}{4}+\frac{1}{16}) \\ RT=2\cdot\frac{4+1}{16}=\frac{5}{8}=0.625 \end{gathered}\)The answer is RT = 5/8 = 0.625

r(x) = 6 ln(1.8)(1.8x); r(x) = 9.3, r(x) = 25
r(x) = 9.3 x = ____
r(x) = 25 x = _____
Answers
Therefore, the value of x for r(x) = 9.3 is 4.1296 and for r(x) = 25 is 18.881 (rounded to three decimal places).
Given that the function
r(x) = 6 ln(1.8)(1.8x)
We need to solve for the input that corresponds to the given output value.
To find r(x) = 9.3, we have to substitute the given value in the given function and solve for x as follows:
6 ln(1.8)(1.8x)
= 9.3ln(1.8)(1.8x)
= 9.3 / 6
= 1.55(1.8x)
= e^(1.55)
x = e^(1.55) / 1.8
x = 4.1296
Thus, x = 4.1296
To find r(x) = 25, we have to substitute the given value in the given function and solve for x as follows:
6 ln(1.8)(1.8x)
= 25ln(1.8)(1.8x)
= 25 / 6
= 4.1667(1.8x)
= e^(4.1667)
x = e^(4.1667) / 1.8
x = 18.881
Thus, x = 18.881

Use the fact that the volume of a tetrahedron with adjacent edges given by the vectors u,v, and w is 1/6|u⋅(v×w)| to determine the volume of the tetrahedron with the following vertices.
P(-3,2,0), Q(2,1,-3), R(1,0,1), S(3,-2,3)
Answers
To use the formula for the volume of a tetrahedron given by the vectors u, v, and w, we need to find the vectors that represent the edges of the tetrahedron with the given vertices.
We can do this by subtracting the coordinates of one vertex from the coordinates of each of the other vertices.
Let u = Q - P = (2 - (-3), 1 - 2, -3 - 0) = (5, -1, -3)
Let v = R - P = (1 - (-3), 0 - 2, 1 - 0) = (4, -2, 1)
Let w = S - P = (3 - (-3), -2 - 2, 3 - 0) = (6, -4, 3)
Now we can substitute these vectors into the formula for the volume of a tetrahedron:
V = 1/6|u⋅(v×w)|
= 1/6|(5, -1, -3) ⋅ ((4, -2, 1) × (6, -4, 3))|
To evaluate the cross product of v and w, we can use the determinant:
| i j k |
| 4 -2 1 |
| 6 -4 3 |
= i(2(3) - (-4)(1)) - j(4(3) - 6(1)) + k(4(-4) - (-2)(6))
= i(10) + j(-6) + k(-8)
= (10, -6, -8)
So we have:
V = 1/6|(5, -1, -3) ⋅ (10, -6, -8)|
= 1/6|(50 + 6 + 24)|
= 1/6|80|
= 40/3
Therefore, the volume of the tetrahedron with vertices P, Q, R, and S is 40/3 cubic units.

The alpha level for each hypothesis test made on the same set of data is called B. experimentwise alpha
What is experimentwise alpha?When numerous suppositions are examined concurrently, the likelihood of committing at least one type I mistake grows.
In order to manage the probability of erroneously rejecting the null hypothesis in all tests, scientists usually modify the alpha level for each test, with the purpose of maintaining an experimentwise alpha that reflects the probability of making a type I error in the entire set of tests.

An electrician earns $43.30 per hour. During 1 week the electrician works these hours: Monday, 8 hours; Tuesday, 7 hours; Wednesday, 5.5 hours; Thursday, 10 hours; and Friday, 4.5 hours. What is the average daily earning
Answers
The average daily earning for the electrician is $303.10.
To find the average daily earning, we first need to find the total earnings for the week.
The electrician worked a total of 35 hours during the week (8 + 7 + 5.5 + 10 + 4.5 = 35).
Multiplying the total hours worked by the hourly rate gives us the total earnings for the week:
35 hours x $43.30/hour = $1,515.50
To find the average daily earning, we divide the total earnings by the number of days worked.

Breast feeding sometimes results in a temporary loss of bone mass as calcium is depleted in the mother's body to provide for milk production.

State and test the appropriate hypotheses using a significance level of 0.05. (Use a statistical computer package to calculate the P-value. Use ?P ? ?B. Round your test statistic to two decimal places and the P-value to three decimal places.)
t =

P =
Conclusion: reject H0 or fail to reject H0
Answers
The data does not suggest that the true average total body bone mineral content during postweaning exceeds that during breastfeeding by more than 25g.
1. Hypotheses:
- Null hypothesis (H0): The true average total body bone mineral content during postweaning is not more than 25g higher than during breastfeeding.
- Alternative hypothesis (H1): The true average total body bone mineral content during postweaning exceeds that during breastfeeding by more than 25g.
2. Test statistic and significance level:
- We will use a t-test to compare the means of the two groups.
- The significance level is given as 0.05.
3. Calculate the test statistic:
- Subtract the bone mineral content during breastfeeding (B) from the bone mineral content during postweaning (P) for each subject.
- Calculate the mean difference and standard deviation of the differences.
- Compute the t-test statistic using the formula: t = (mean difference - 25) / (standard deviation / √n), where n is the number of observations.
4. Degrees of freedom (df):
- The degrees of freedom for this test is equal to the number of observations minus 1.
5. P-value:
- Use a statistical computer package to calculate the P-value associated with the obtained test statistic and degrees of freedom.
6. Decision:
- Compare the P-value to the significance level.
- If the P-value is less than the significance level (0.05), reject the null hypothesis.
- If the P-value is greater than or equal to the significance level, fail to reject the null hypothesis.
In this case, the conclusion is based on the calculated P-value. If the P-value is less than 0.05, we would reject the null hypothesis, indicating that the true average total body bone mineral content during postweaning does exceed that during breastfeeding by more than 25g. If the P-value is greater than or equal to 0.05, we would fail to reject the null hypothesis, suggesting that there is not enough evidence to conclude that the average bone mineral content during postweaning is significantly higher than during breastfeeding by more than 25g.
