Rhonda is painting four pictures on paper. She has 1/8 of a gallon of paint to paint all the pictures. How much paint will she use for each painting if she uses the same amount of paint on each
Answers
Answer:
1/32
Step-by-step explanation:
To determine the amount of paint she would use for a picture, divide the total gallon of paint by the number of pictures
Paint she would use for one painting = total gallons of paint / number of pictures
1/8 ÷ 4
= 1/8 x 1/4
= 1/32
In speech class, Carolyn needs at least a B + to keep her financial aid. To earn a B+, the average of her four speeches must be at least an 85. On the first 3 she scored 85, 77, and 81. Determine the minimum score speech to get a B+.
Answers
Answer:
The minimum score speech to get a B+ is 89.Step-by-step explanation:
Average of the first 3 = 85 + 77 + 81 / 3
= 243 / 3
= 81
The fourth score ( to get 85 ) = 81 + 89
= 170 / 2
= 85
Answer:
97
Step-by-step explanation:
Relative to the average she wants, Carolyn's scores are ...
85-85 = 0
77-85 = -8
81-85 = -4
Carolyn's score total is -8-4 = -12 points from the average she wants, so she must get 85+12 = 97 on her speech to achieve a B+ average.
_____
Check
With a 97, Carolyn's average would be ...
(85 +77 +81 +97)/4 = 340/4 = 85

A pencil manufacturer makes a giant model pencil, 3m long. A real pencil is 18cm long and has a volume of 9cm(cube). Find the volume in m(cube) of the giant model.
NOTE: EXPLANATION IS REQUIRED.
Answers
Answer:
We always need an equation relating the given information to what is to be found. With this problem, we must assume that the giant model is proportional to the standard pencil.
3 m: 18 cm :: Vg:9 cm^3 where Vg is the volume of the giant pencil.
Before any calculations are performed all units must be the same.
The 3 m large pencil must be converted to cm. Each meter is 100 centimeters. Therefore: the proportion must be adjusted to:
300 cm : 18 cm :: Vg : 9 vm^3
300/18 = Vg/9 Now solve.
300 x 9 = 18 Vg By cross multiple
2700 = 18 Vg Divide both sides by 18
Vg = 2700/18 = 150 cm^3 = 0.00015 m^3
Conversion Factor: 1 cm^3 = 10^-6 m^3 Divide by 10^6.

Group A is on the north side of the fire and is 800 ft away from group B and 900 feet away from group C. Group A knows that the angle between its two adjacent sides is 89.6. “
The emergency responders want to properly inform the nearby towns of the danger proximity. They will need all three angles. To do this they need some additional information. The emergency responders need to know the angle of Group B and Group C. They also need to know the distance between Groups B and C.
Answers
Answer:
1. Length BC is 1200 ft
2. Angle B is 48.6°
3. Angle C is 41.8°
Step-by-step explanation:
1. Determination of the length BC
Side opposite C = c = 800 ft
Side opposite B = b = 900 ft
Angle A = 89.6°
Side opposite BC = a =?
Using cosine rule, we can obtain length BC as follow:
a² = b² + c² – 2bc CosA
a² = 900² + 800² – 2 × 900 × 800 × Cos89.6
a² = 810000 + 640000 – 1440000 × 0.007
a² = 1450000 – 10080
a² = 1439920
Take the square root of both side
a = √1439920
a ≈ 1200 ft
Thus, length BC is 1200 ft
2. Determination of angle B
Side opposite B = b = 900 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle B =?
Angle B can be obtained by using sine rule as follow:
a / Sine A = b / Sine B
1200 / Sine 89.6° = 900 / Sine B
Cross multiply
1200 × Sine B = 900 × Sine 89.6°
1200 × Sine B = 900
Divide both side by 1200
Sine B = 900/1200
Sine B = 0.75
Take the inverse of Sine
B = Sine¯¹ 0.75
B = 48.6°
Thus, angle B is 48.6°
3. Determination of angle C
Side opposite C = c = 800 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle C =?
Angle C can be obtained by using sine rule as follow:
a / Sine A = c / Sine C
1200 / Sine 89.6° = 800 / Sine B
Cross multiply
1200 × Sine C = 800 × Sine 89.6°
1200 × Sine C = 800
Divide both side by 1200
Sine C = 800/1200
Sine C = 0.6667
Take the inverse of Sine
C = Sine¯¹ 0.6667
C = 48.6°
Thus, angle C is 41.8°

Not all visitors to a certain company's website are customers. In fact, the website administrator estimates that about 5% of all visitors to the website are looking for other websites. Assuming that this estimate is correct, find the probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website. Round your response to at least three decimal places.
Answers
Answer:
0.0135 = 1.35% probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.
Step-by-step explanation:
For each visitor of the website, there are only two possible outcomes. Either they are looking for the website, or they are not. The probability of a customer being looking for the website is independent of other customers. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
5% of all visitors to the website are looking for other websites.
So 100 - 5 = 95% are looking for the website, which means that [tex]p = 0.95[/tex]
Find the probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.
This is P(X = 2) when n = 4. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = x) = C_{4,2}.(0.95)^{2}.(0.05)^{2} = 0.0135[/tex]
0.0135 = 1.35% probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.

Lucy went to the store with $50. She bought a pair of jeans for $14.99, three shirts for $4 each, and a bag of Cheetos for $2.25. While at the store, she found another $10 in the bottom of her purse. How much money did Lucy have when she left the store?
Answers
Answer:
$30.76
Step-by-step explanation:
Subtract the costs of her purchases from her total of 50:
50 - (14.99 + 3(4) + 2.25)
50 - (14.99 + 12 + 2.25)
50 - 29.24
= 20.76
Now, add the $10 that she found to this:
20.76 + 10
= 30.76
So, when she left the store, Lucy had $30.76

Find the sample variance and standard deviation of:
21, 12, 3, 9, 11
s2=?
Answers
Answer:
42. 2
6.496
Step-by-step explanation:
Given the data :
21, 12, 3, 9, 11
Variance :
S² = Σ(x - m)² ÷ (n - 1)
n = sample size = 5
m = sample mean = Σx / n
m = (21 + 12 + 3 + 9 + 11) / 5
m = 11. 2
(21-11.2)² + (12 -11.2)² + (3 - 11.2)² + (9-11.2)²
+ (11-11.2)² / (5 - 1)
S² = 42.2
Standard deviation, s = sqrt(42.2) = 6.496
