A density curve for all the possible ages between 0 years and 50 years is in the shape of a triangle. What is the height of the triangle? O A. 0.04 O B. 0.02 O c. 0.01 O D. 0.08 SUBMIT
Answer:
0.04
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of triangle :
Area = 1/2 base * height
Base = 0 - 50 = 50
Area = 1
Hence,
1 = 1/2 * 50 * h
1 = 50h / 2
2 = 50h
h = 2 / 50
h = 0.04
A random sample of 432 voters revealed that 100 are in favor of a certain bond issue. A 95 percent confidence interval for the proportion of the population of voters who are in favor of the bond issue is A 100 + 1.96 0.5(0.5) 432 100 + 1.645 0.5(0.5) 432 100 + 1.96 0.231(0.769) 432 0.231 +1.96 0.231(0.769) 432 0.231(0.709) 0.231 +1.6451 432
Answer:
The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A random sample of 432 voters revealed that 100 are in favor of a certain bond issue.
This means that [tex]n = 432, \pi = \frac{100}{432} = 0.231[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Confidence interval:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]
The 95% confidence interval is [tex]0.231 \pm 1.96\sqrt{\frac{0.231*0.769}{432}}[/tex]

an investment of Rs 100000 is made which on interest at the rate of 8% per year if the interest is compounded continuously to what value with investment grow in 7 year period
Answer:
A = $174,742.21
A = P + I where
P (principal) = $100,000.00
I (interest) = $74,742.21
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 100,000.00(1 + 0.08/12)(12)(7)
A = 100,000.00(1 + 0.006666667)(84)
A = $174,742.21
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 8% per year compounded 12 times per year over 7 years is $174,742.21.

Answer:
It is a Cuboid
Area of the base = 12x9
Area of the top = 12x9
Area of the right lateral faces = 9x7
Area of the left lateral faces = 9x7
Area of the front face = 12x7
Area of the rear face = 12x7
Total surface area is the sum of above (please do it yourself)
The volume = base surface Area x height
= 12x9x7 = 756
Be reminded to put in the right unit for Area and volumn
Answer:
its a prism
Step-by-step explanation:
to find area of all the sides, you multiply the bottom and top measurements.
12 x 7 is 84cm[tex]^{2}[/tex]
12 x 9 is 108[tex]cm^{2}[/tex]
9 x 7 is 63[tex]cm^{2}[/tex]
for surface area, add the area of all the faces
63x2+108x2+84X2=510
volume is length x width x hight
12 x 9 x 7 = 756 [tex]cm^{3}[/tex]

Find the measure of the remote exterior angle. (Angles above)
9514 1404 393
Answer:
B. 66°
Step-by-step explanation:
The remote exterior angle (z) is the sum of the measures of the interior angles (x, y).
x + y = z
(5n -19) +(n +7) = (144 -6n)
12n = 156 . . . . . . . . . . . . . . . . . add 6n+12
n = 13 . . . . . . . . . . . . . . divide by 12
Then the measure of the remote exterior angle is ...
m∠z = (144 -6(13))° = (144 -78)°
m∠z = 66°
__
x = 46°
y = 20°
The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test H0: p 0.28 vs Ha: p 0.28 when the sample has n 900 , and p ^ 0.216 with SE 0.01 . Find the value of the standardized z -test statistic.
Answer:
The value of the standardized z-test statistic is -6.4.
Step-by-step explanation:
The test statistic is:
[tex]z = \frac{X - \mu}{s}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, and s is the standard error.
0.28 is tested at the null hypothesis:
This means that [tex]\mu = 0.28[/tex]
p ^ 0.216 with SE 0.01
This means that [tex]X = 0.216, s = 0.01[/tex]
Then
[tex]z = \frac{X - \mu}{s}[/tex]
[tex]z = \frac{0.216 - 0.28}{0.01}[/tex]
[tex]z = -6.4[/tex]
The value of the standardized z-test statistic is -6.4.

fraction math kids picked 124 strawberries gave 1/4 of strawberries to their neighbor and their mother used f 2/4 of the strawberries in a pie rest was saved for snack how many does the family have to snack on
Answer:
The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.
Step-by-step explanation:
Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.
Ignore the rotation 90 clockwise
Answer:
A reflection about y=x
Step-by-step explanation:
The 4 transformations are
TranslationRotationReflectionDilationLet eliminate which ones won't work.
A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.
A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.
A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.
A reflection will work so what will we reflect about.
Some corresponding coordinates are5,6 and 7,61,6 and 7,23,8 and 9,4.A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.
So let find the midpoint of all the points and find a line where all of them are on.
The midpoint respectively are
6,64,46,6Let find the line that includes both these points.
[tex] \frac{6 - 4}{6 - 4} = \frac{2}{2} = 1[/tex]
So this means our slope is x. The y value corresponds with the x value so the answer is
[tex]y = x[/tex]
So the answer is
"A reflection about y=x

Answer:
[tex]volume \: of \: the \: rectriangular \: prism = ( \frac{1}{2} \times base \times 4) \times 2 \\ 4 \times base = 40 \\ base = 10m[/tex]
Answer:
length = 15 meters
Step-by-step explanation:
Volume of a pyramid is:
V = l*w (h/3)
We know that; Volume is 40, Width is 2, and Height is 4, therefore;
40 = l*2 (4/3)
40 = 2l (4/3)
(3/4) * 40 = 2L
30 = 2L
30/2 = L
15 = L
therefore the length = 15 meters
Hope this helps!
Find the area of the shaded religion.
Giving brainliest! <3
Answer: 240 feet
Step-by-step explanation:
What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.
Answer:
The answer is : 240cm² for the shaded part
The unshaded part is = 60cm²
The whole rectangle = 300cm²
Step-by-step explanation:
Area is = WL
W = width (while the) L= length
The Area = 25 × 12 = 300
The area of the full rectangle is = 300
The unshaded part is = 5 × 12 = 60
So the shaded part is = 300 - 60 = 240cm²
[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]
