Answer:
23, 15 and 45
Step-by-step explanation:
a+b+c = 83
a = b + 8
c = 3*b
(b+8) + b + 3*b = 83
5*b + 8 = 83
5*b = 75
b = 15
a = b + 8 = 15 + 8 = 23
c = 3*b = 3*15 = 45
Verification
a+b+c = 23 + 15 + 45 = 83; correct

A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest. Historical data indicates that 20% of all potential purchasers select a day visit, 50% choose a one-night visit, and 30% opt for a two-night visit. In addition, 30% of day visitors ultimately make a purchase, 10% of one-night visitors buy a unit, and 50% of those visiting for two nights decide to buy. Suppose a visitor is randomly selected and is found to have made a purchase. How likely is it that this person made a day visit
Answer:
0.2308 = 23.08% probability that this person made a day visit
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Visitor made a purchase
Event B: Made a day visit
Probability that a visitor made a purchase:
30% of 20%(day visitors)
10% of 50%(one-night)
50% of 30%(two-night)
So
[tex]P(A) = 0.3*0.2 + 0.1*0.5 + 0.5*0.3 = 0.26[/tex]
Probability of a purchase with a day visit:
30% of 20%. So
[tex]P(A \cap B) = 0.3*0.2 = 0.06[/tex]
How likely is it that this person made a day visit?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.26} = 0.2308[/tex]
0.2308 = 23.08% probability that this person made a day visit

A 10-ounce container of chocolate chips can be used to make 4 desserts.
Each dessert has the same number of chocolate chips.
Which equation shows how to find the number of ounces in each dessert?
A number line going from 0 to 10 in increments of 1.
10÷4=104 ounces
4÷10=104 ounces
10÷4=410 ounce
4÷10=410 ounce
Answer:
So equation will be 4x = 10
A 10 ounce container of chocolate chips can be used to make 4 desserts.
Each desert has the same number of chocolate chips
Let number of chocolate chips in each dessert = x ounce
Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.
So equation will be 4x = 10

Answer:
C. [tex] \frac{8\sqrt{89}}{89} [/tex]
Step-by-step explanation:
Cos A = Adj/Hyp
Reference angle = <A
Adjacent side = 8 ft
Hypotenuse = √(8² + 5²) = √89 (pythagorean theorem)
Thus:
[tex] Cos (A) = \frac{8}{\sqrt{89}} [/tex]
Rationalize
[tex] Cos (A) = \frac{8 * \sqrt{89}}{\sqrt{89} * \sqrt{89}} [/tex]
[tex] Cos (A) = \frac{8\sqrt{89}}{89} [/tex]

Step-by-step explanation:
pretty sure I answered this exact question like minutes ago
Answer: 257/24, or 10 and 17/24.
Step-by-step explanation:
First, we need to turn the fractions into improper fractions and then find the common denominator.
4 and 5/6 = 29/6
5 and 7/8 = 47/8
The common denominator is 24. Now, we convert the fractions and add. Hope this helps!

Function A and Function B are linear functions. Compare the two functions and choose all that are correct. Can someone help?
Answer:
(b) and (c) are true
Step-by-step explanation:
Given
Function A and B
First, calculate the slope of A
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{24 - -21}{8- -7}[/tex]
[tex]m = \frac{45}{15}[/tex]
[tex]m =3[/tex]
The equation of function A is:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 3(x - 8) + 24[/tex]
[tex]y = 3x - 24 + 24[/tex]
[tex]y = 3x[/tex]
The general form of a function is:
[tex]y = mx + b[/tex]
Where [tex]m = slope[/tex] and [tex]b = y\ intercept.[/tex]
This implies that:
[tex]Slope = 3[/tex]
[tex]Y\ intercept = 0[/tex]
For function B:
[tex]y = 4x - 3[/tex]
[tex]Slope = 4[/tex]
[tex]Y\ intercept = -3[/tex]
By comparison:
(b) and (c) are true

Step-by-step explanation:
Identify the angles , solve for x
Answer:
Consecutive interior angles ; x = 20
Step-by-step explanation:
These are known as consecutive interior angles. This means they are equal to each other. Knowing this, we can set up an equation to solve for x.
4x - 30 = 2x + 10
2x - 30 = 10
2x = 40
x = 20
