Chico is financing a car for $9,550 and an APR 8.9 percent for 3 years. What is his monthly payment if the monthly payment per $100 is $3.52?
A. $336.16
B. $352
C. $251.48
D. $235.24
(I divided 9550 by 100 and then multiplied that by 3.52 and got A but I don't know if that's the right way to do it)
Answer:
A. $336.16
Step-by-step explanation:
The payment per $100 can be set up as a ratio:
[tex]\frac{3.52}{100}[/tex]
Let the unknown payment be x. Now setting up the ratio over the full value:
[tex]\frac{x}{9550}[/tex]
Set them equal and solve for x:
[tex]\frac{3.52}{100}=\frac{x}{9550}[/tex]
1[tex]100x=33616[/tex]
This gives x = $336.16
Therefore, the answer is option A.

You decide to play roulette 200 times each time betting the same amount on red. you will loe money if you win on fewer than 100 of the plays. what is the probability that you will lose money? ( check that the normal approximation is permissible and use it to find this probability) in general, if you bet the same.
The probability of losing money in this scenario is 23.89%.
Probability of Losing Money in Roulette (200 spins, red bet)
Step-by-Step Calculation:
1) Probability of winning on one spin:
Red covers 18 out of 38 numbers (European roulette).
P(win) = 18/38 ≈ 0.474.
2) Number of wins needed to break even:
Divide total spins by 2 due to 1:1 payout on red.
200 spins / 2 = 100 wins needed.
3) Binomial distribution:
200 trials (spins), each with 2 outcomes (win/loss).
Success probability = P(win) = 0.474.
Failure probability = P(loss) = 1 - P(win) = 0.526.
4) Normal approximation:
Check conditions for normal approximation:
np > 5 (200 × 0.474 ≈ 95 > 5)
nq > 5 (200 ×0.526 ≈ 105 > 5)
Both conditions met, so normal approximation is valid.
5) Calculate mean and standard deviation:
Mean (μ) = np = 200 × 0.474 ≈ 94.8.
Standard deviation (σ) = sqrt(npq) = sqrt(200 * 0.474 * 0.526) ≈ 7.4.
6) Find probability of losing money:
We need wins < 100, which translates to losses ≥ 100.
Convert losses to z-scores:
z = (x - μ) / σ = (100 - 94.8) / 7.4 ≈ 0.71.
Look up probability of z ≥ 0.71 in standard normal distribution table:
P(z ≥ 0.71) ≈ 0.2389.
7) Generalization:
For any number of spins (n) and break-even win threshold (k), the steps are similar. Use the binomial distribution or its normal approximation to calculate the probability of winning k or fewer times.

△E′F′G′ is the image of △EFG under a dilation through point C.
What scale factor was used in the dilation?
the correct answer is - 1/2
Answer: The value of the scale factor is [tex]-\frac{1}{2}[/tex].
Explanation:
It is given that the △E′F′G′ is the image of △EFG under a dilation through point C.
We know that the length of sides of image are in the proportion of length of sides of preimage. That proportion factor is also known as scale factor.
It is given that the length of FG is 8 cm and the length of F'G' is 4 cm.
[tex]k=\frac{F'G'}{FG} =\frac{4}{8} =\frac{1}{2}[/tex]
Therefore the side of image and preimage are in proportion of [tex]\frac{1}{2}[/tex].
Since the image and preimage are not on the same side of the center of dilation it means the factor must be negative. So,
[tex]k=-\frac{1}{2}[/tex].
Therefore, [tex]-\frac{1}{2}[/tex] is the scale factor of dilation.

A package is in the shape of a triangular prism. The bases are right triangles with perpendicular legs measuring 9 centimeters and 12 centimeters. The distance between the bases is 10 centimeters. What is the surface area of the triangular prism? square centimeters
The surface area of the triangular prism is 468 (square cm).
The surface area A of a triangular prism is given by the formula:
[tex]\[ A = 2A_{\text{base}} + P_{\text{base}} \times h \][/tex]
where:
- [tex]\( A_{\text{base}} \)[/tex] is the area of one of the triangular bases,
- [tex]\( P_{\text{base}} \)[/tex] is the perimeter of one of the triangular bases,
- h is the distance between the bases.
The area of a right triangle is given by:
[tex]\[ A_{\text{base}} = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]
And the perimeter of a right triangle is the sum of the lengths of its three sides.
Given that the legs of the right triangles forming the bases are 9 cm and 12 cm, and the distance between the bases is 10 cm, we can calculate the surface area.
1. Area of the triangular base [tex](\(A_{\text{base}})\)[/tex]:
[tex]\[ A_{\text{base}} = \frac{1}{2} \times 9 \times 12 \][/tex]
2. Perimeter of the triangular base [tex](\(P_{\text{base}})\)[/tex]:
[tex]\[ P_{\text{base}} = 9 + 12 + \sqrt{9^2 + 12^2} \][/tex]
3. Surface area of the triangular prism A:
[tex]\[ A = 2 \times A_{\text{base}} + P_{\text{base}} \times 10 \][/tex]
Calculate each part and find the total surface area.
[tex]\[ A_{\text{base}} = \frac{1}{2} \times 9 \times 12 = 54 \, \text{cm}^2 \][/tex]
[tex]\[ P_{\text{base}} = 9 + 12 + \sqrt{9^2 + 12^2} = 9 + 12 + 15 = 36 \, \text{cm} \][/tex]
[tex]\[ A = 2 \times 54 + 36 \times 10 = 108 + 360 = 468 \, \text{cm}^2 \][/tex]
So, the surface area of the triangular prism is [tex]\(468 \, \text{cm}^2\)[/tex].
If the center of a circle is (1, 1), and it has a radius of 5, which is another point on the circle?
Answer:
Step-by-step explanation:
The equation of this circle is:
(x - 1)² + (y - 1)² = 5²
Just supposing we choose x = 2. What's the corresponding y-value?
Actually, there are two unique y-values for each x value.
Let x = 2 in (x - 1)² + (y - 1)² = 5². Then:
(2 - 1)² + (y - 1)² = 5², or
1² + (y - 1)² = 25
Solving for (y - 1)², we get (y - 1)² = 25 - 4, or 24.
Taking the square root of both sides:
y - 1 = ±√24, so that y = 1 ±√24,
This simplifies to y = 1 ± 2√6.
Therefore, if x = 2, y has two values:
(2, 1+2√6) and
(2, 1-2√6

Zoe is taking the measurements of her lawn. her lawn is 64.15 feet long and 22.70 meters wide. one foot is equivalent to 0.3048 meters. which dimension of zoe's lawn is longer, and how many yards longer is it?
Answer:
width of the lawn is greater than the length of the lawn.Step-by-step explanation:
The length of her lawn=64.15 feet.
Width of her lawn=22.70 meters.
we are given that:
1 foot=0.3048 meters.
Hence,
64.15 feet=21.86232 meters.
Hence, length of lawn=21.86232 meters.
Hence, width of the lawn is greater than the length of the lawn.
( since 22.70 meters> 21.862332 meters)
Also 1 meter=1.0936 yards.
so, width of lawn in yards is:
22.70×1.0936=24.82472 yards.
length of lawn is: 23.9086462752 yards.
Hence, width of lawn is 0.9160737 yards more than the length of lawn.
In a garden the heights of six sunflowers are 135.0 cm, 162.5 cm, 180.0 cm, 235.0 cm, 185.0 cm, and 167.5 cm. What is the average height of the sunflowers?
135 + 162.5 + 180 + 235 + 185 + 167.5 = 1065
1065/6 = 177.5
average height is 177.5 cm
Answer:
Average height of sunflowers is:
177.5 cm
Step-by-step explanation:
Average is calculated as sum of all observations divided by number of observations
The heights of six sunflowers are 135.0 cm, 162.5 cm, 180.0 cm, 235.0 cm, 185.0 cm, and 167.5 cm.
Average= [tex]\dfrac{135+162.5+180+235+185+167.5}{6}[/tex]
Average= [tex]\dfrac{1065}{6}[/tex]
Average= 177.5
Hence, Average height of sunflowers is:
177.5 cm

Ammon and nakia volunteer at an animal shelter. nakia worked 3 more hours than ammon. they each worked a whole number of hours. together they worked more than 27 hours. what is the least number of hours each worked
Final answer:
The least number of hours Ammon could have worked is 13 hours, and Nakia worked 16 hours since Nakia worked 3 hours more than Ammon, and together they worked more than 27 hours.
Explanation:
Let's denote the number of hours that Ammon worked as A and the number of hours that Nakia worked as N. According to the question, Nakia worked 3 more hours than Ammon, which can be written as N = A + 3. It's also given that together they worked more than 27 hours, so we can write this as A + N > 27. Substituting the first equation into the second, we get A + (A + 3) > 27, which simplifies to 2A + 3 > 27. By subtracting 3 from both sides, we get 2A > 24. Dividing by 2 gives us A > 12. Since A must be a whole number, the smallest whole number greater than 12 is 13.
Now that we know A is at least 13, we can find the minimum number of hours Nakia worked, which is A + 3. That gives us N = 13 + 3 = 16. Therefore, the least number of hours Ammon worked is 13 hours and Nakia worked 16 hours.
