Answer:
60 degrees and 100 degrees
Step-by-step explanation:
360 - (190 + 10) = sum of other two angles
360 - 200 = 160
160/(3+5) = 160/8 = 20
20 × 3 = 60 degrees, 20 × 5 = 100 degrees

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.47 and a standard deviation of 1.5. Using the empirical rule, what percentage of American women have shoe sizes that are greater than 11.47? Please do not round your answer.
Answer:
2.5% of American women have shoe sizes that are greater than 11.47.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 8.47
Standard deviation = 1.5
The normal distribution is symmetric, which means that half the measures are below the mean, and half are above the mean.
What percentage of American women have shoe sizes that are greater than 11.47?
11.47 = 8.47 + 2*1.5
This means that 11.47 is two standard deviations above the mean.
Of those measures below the mean, none are greater than 11.47.
Of those measures above the mean, 95% are between the mean and 11.47, and 5% are above. So
0.5*0.05 = 0.025
2.5% of American women have shoe sizes that are greater than 11.47.

A chemical company makes two brands of antifreeze. The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. In order to obtain 30 gallons of a mixture that contains 30% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Answer:
First brand = 18 gallons
Second brand = 12 gallons
Step-by-step explanation:
Let the first brand brand be A and the second brand be B.
Thus, since he wants to obtain 30 gallons of a mixture that contains 30% pure antifreeze, then we have;
A + B = 30 - - - (eq 1)
Also; The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. Thus;
0.2A + 0.45B = (0.3 × 30)
0.2A + 0.45B = 9 - - - (eq 2)
From eq 1, we have; A = 30 - B
Put 30 - B for A in eq 2;
0.2(30 - B) + 0.45B = 9
6 - 0.2B + 0.45B = 9
0.25B = 9 - 6
0.25B = 3
B = 3/0.25
B = 12
Thus, A = 30 - 12 = 18 gallons
Gasoline price changed from $3.25/gallon to $1.30/gallon in one week. What is the percent of change? PLZ I need it fast!! I will give 10 points
Answer:
The percent of change is -60%.
Step-by-step explanation:
To find the percentage of change, we find the percentage of the final value, considering the initial valuie is 100%, and then we subtract 100% by the percengate found.
In this question:
Initial price of $3.25 per gallon, which is 100% = 1.
Final value of $1.30, which is x. So
$3.25 - 1
$1.30 - x
[tex]3.25x = 1.30[/tex]
[tex]x = \frac{1.30}{3.25}[/tex]
[tex]x = 0.4[/tex]
The initial value of 0.4 = 40% of the initial value.
So the percent of change is a decrease of 100% - 40% = 60%, that is, -60%.

Use the following information to answer the question. Suppose that the probability that a person books a hotel using an online travel website is 0.68. For the questions that follow, consider a sample of fifteen randomly selected people who recently booked a hotel. What is the probability that no more than four out of fifteen people used an online travel website when they booked their hotel
Answer:
0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they booked the hotel using an online travel website, or they did not. Each person is independent of each other. So we use the binomial probability distribution 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.
Suppose that the probability that a person books a hotel using an online travel website is 0.68.
This means that [tex]p = 0.68[/tex]
Sample of fifteen:
This means that [tex]n = 15[/tex]
What is the probability that no more than four out of fifteen people used an online travel website when they booked their hotel
[tex]P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)[/tex]
So
[tex]P(X = 0) = C_{15,0}.(0.68)^{0}.(0.32)^{15} = 0[/tex]
[tex]P(X = 1) = C_{15,1}.(0.68)^{1}.(0.32)^{14} = 0[/tex]
[tex]P(X = 2) = C_{15,2}.(0.68)^{2}.(0.32)^{13} = 0[/tex]
[tex]P(X = 3) = C_{15,3}.(0.68)^{3}.(0.32)^{12} = 0.0002[/tex]
[tex]P(X = 4) = C_{15,4}.(0.68)^{4}.(0.32)^{11} = 0.0011[/tex]
[tex]P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0 + 0 + 0 + 0.0002 + 0.0011 = 0.0013[/tex]
0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel

Answer:
a = 66⁰
b = 33⁰
Step-by-step explanation:
Given;
∠ABC = 114⁰
To calculate a⁰;
a + 114 = 180⁰ (opposite angles of a quadrilateral are supplementary)
a = 180 - 114
a = 66⁰
To calculate b⁰;
Line AB = Line BC, thus, ∠BAC = ∠BCA
∠BAC = b, then ∠BCA = b
b + b + 114 = 180 (sum of angles in a triangle)
2b = 180 - 114
2b = 66
b = 66/2
b = 33⁰
Use the prescription below to answer the following question Chlorpheniramine 100ml Lidocaine 2oz Banna flavoring 1/2 tsp Take 10ml BID what is the final volume in mL?
Answer:
86.5ml...hope I am right
The final volume of the mixture is 161.61146 milliliters (ml) as per the data given in the prescription.
What is prescription?A prescription, also known as a Rx, is a formal communication from a doctor or other registered health-care professional to a pharmacist.
The prescription indicates that Chlorpheniramine comes in a 100ml bottle, Lidocaine comes in a 2oz bottle, and 1/2 tsp of banana flavoring is to be added. The prescription instructs to take 10ml of the mixture twice a day (BID).
First, we need to convert the 2oz of Lidocaine into milliliters. One fluid ounce (oz) is equivalent to approximately 29.5735 milliliters (ml). Therefore, 2oz of Lidocaine is equal to:
2 oz x 29.5735 ml/oz = 59.147 ml
Next, we need to add 1/2 tsp (teaspoon) of banana flavoring to the mixture. One teaspoon is equivalent to approximately 4.92892 milliliters (ml). Therefore, 1/2 tsp of banana flavoring is equal to:
1/2 tsp x 4.92892 ml/tsp = 2.46446 ml
To find the final volume of the mixture, we add the volumes of Chlorpheniramine, Lidocaine, and banana flavoring:
Final volume = Chlorpheniramine volume + Lidocaine volume + Banana flavoring volume
Final volume = 100ml + 59.147ml + 2.46446ml
Final volume = 161.61146 ml
Therefore, the final volume of the mixture is 161.61146 milliliters (ml).

for what value of the variable the value of the expression 4(5x-8) is 4 more than the value of the expression 2(4-x)
Answer:
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Step-by-step explanation:
Given expressions are;
4(5x-8) and 2(4-x)
For 4 more than the second expression, we will add 4 with second expression.
4(5x-8) = 2(4-x) + 4
20x - 32 = 8 -2x +4
20x + 2x = 12 + 32
22x = 44
Dividing both sides by 22
[tex]\frac{22x}{22}=\frac{44}{22}\\x=2[/tex]
Hence,
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)

2.5m + 10 = 1.6m - 6
Answer:
m = 17.78.
Step-by-step explanation:
Given the algebraic expression;
2.5m + 10 = 1.6m - 6
To find the value of m;
First of all, we would collect like terms.
2.5m - 1.6m = -6 - 10
0.9m = -16
m = -16/0.9
m = 17.78
Have to use laws of sines, can someone solve this one?
Answer/Step-by-step explanation:
✔️Find <K using law of sines:
Thus,
[tex] \frac{sin(K)}{k} = \frac{sin(H)}{h} [/tex]
K = ??
k = 37 mm
H = 34°
h = 29 mm
Plug in the values
[tex] \frac{sin(K)}{37} = \frac{sin(34)}{29} [/tex]
Multiply both sides by 37
[tex] \frac{sin(K)}{37}*37 = \frac{sin(34)}{29}*37 [/tex]
[tex] sin(K) = \frac{sin(34)*37}{29} [/tex]
[tex] sin(K) = 0.713453014 [/tex]
[tex] K = sin^{-1}(0.713453014) [/tex]
[tex] K = 45.5 degrees [/tex] (nearest tenth)
✔️Find J:
m<J = 180° - (45.5° + 34°) (sum of ∆)
m<J = 100.5°
✔️Find j using Sine rule:
[tex] \frac{j}{sin(J)} = \frac{h}{sin(H)} [/tex]
J = 100.5°
j = ??
H = 34°
h = 29 mm
Plug in the values
[tex] \frac{j}{sin(100.5)} = \frac{29}{sin(34)} [/tex]
Multiply both sides by sin(100.5)
[tex] \frac{j}{sin(100.5)}*sin(100.5) = \frac{29}{sin(34)}*sin(100.5) [/tex]
[tex] j = \frac{29*sin(100.5)}{sin(34)} [/tex]
j = 51.0 mm (nearest tenth)

Sheryl spends $9 every week on cigarettes and spends $38 a month on dry cleaning.
On an annual basis, the money spent on cigarettes is % of the money spent on dry cleaning.
Answer:
102.63
Step-by-step explanation:
There are 12 months in a year. 12 * 38 = 456
There are 52 weeks in a year 52 * 9 = 468
Cigarettes : dry cleaning :: 468:456
Cigarettes : dry cleaning :: 1.0263
The % is (468/456)*100 = 102.63%
The % shows that she spends more on cigarettes than she does on dry cleaning, which is usually the case.
Chuck and holly are saving money to buy a car. Chuck has $500.00 already and is going to save $100.00 a month. Holly has $1000.00 and plans on saving 50 a month and it takes 10 months for their savings to equal. Write anequation
Answer:
500 + 100m = 1000 + 50m
Step-by-step explanation:
In order to form an equation we need atleast on variable which in this scenario would be the number of months (m). We can say that we know that sooner or later their savings will equal. Therefore, we can create the following equations for each of their savings progress which are equal to one another...
500 + 100m = 1000 + 50m
This equation if solved would give us the value of 10 for the variable m, meaning that their savings will equal in 10 months. To find out how much each will have in 10 months we can simply grab one half of the equation and substitute 10 for m
500 + 100(10) = x
500 + 1000 = x
1500 = x
Finally, we can see that after 10 months they would both have $1500 saved up.
