Answer:
0.58 = 58% probability she passes both courses
Step-by-step explanation:
We can solve this question treating the probabilities as a Venn set.
I am going to say that:
Event A: She passes the first course.
Event B: She passes the second course.
The probability she passes the first course is 0.67.
This means that [tex]P(A) = 0.67[/tex]
The probability she passes the second course is 0.7.
This means that [tex]P(B) = 0.7[/tex]
The probability she passes at least one of the courses is 0.79.
This means that [tex]P(A \cup B) = 0.79[/tex]
a. What is the probability she passes both courses
This is [tex]P(A \cap B)[/tex].
We use the following relation:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58[/tex]
0.58 = 58% probability she passes both courses

Step-by-step explanation:
From 8 am to 3 pm, there are 7 hours, and the price changed $2 (52 - 50 = 2)
In order to find the Change in price per hour, divide the total price change by the number of hours. (in most questions with the word "per", it is a division problem)
2$ / 7hrs = 2/7 dollars per hour

A shoe store is selling a pair of shoes for $60 that has been discontinued by 25%. What was the original selling price?
show your work plssss!!
Answer:
$80
Step-by-step explanation:
The shoe is being sold for 75% (100%-25%) of the original price. So in order to calculate the original price, divide the discounted price ($60) by 75%.
60/0.75 = 80

Negation
a. n is divisible by 6 and either n is not divisible by 2 or n is not divisible by 3.
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
c. If n is divisible by 2 and n is divisible by 3, then n is divisible by 6.
d. If n is not divisible by 6, then n is not divisible by 2 or n is not divisible by 3.
e. If n is not divisible by 6, then n is divisible by 2 and n is divisible by 3.
Answer:

Step-by-step explanation:
Division by Six
A number is divisible by six if it is divisible by both 2 and 3.
Negation:
If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.
b.
Step-by-step explanation:
Division by Six
A number is divisible by six if it is divisible by both 2 and 3.
Negation:
If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.
Special Cases
8x+3-10x=2(x-2)+3
Answer:
x = 1
Step-by-step explanation:
8x + 3 - 10x = 2(x - 2) + 3
Distribute the 2
8x + 3 - 10x = 2x - 4 + 3
Combine like terms
-2x + 3 = 2x - 1
Add 1 to both sides
-2x + 4 = 2x
Add 2x to both sides
4 = 4x
Divide both sides by 4
x = 1
John began his job making $125 the first week. After that he ws paid $6.25 per hour. Write the equation in slope intercept form to represent the situation.
Answer:
y=6.25x+125
Step-by-step explanation:
Given that,
John began his job making $125 the first week. After that he was paid $6.25 per hour.
Here $125 is fixed and $6.25 increase per hour. It means we can write the equation as follows :
y = 125 + 6.25 x
The general equation for the slope-intercept form is given by :
y = mx+x
m is slope
So, the equation in slope intercept form is given by :
y=6.25x+125
Hence, this is the required solution.
a) y= 0.05x + 16
b) y= 6.25x + 125
c) y= 2x + 10
d) y= 3x + 5
Answer: B) y = 6.25x + 125

[tex]\color{plum}\tt2x + 7° = \underline{65} \: degrees[/tex]
Steps to derive the correct solution :The exterior angle corollary states that the measure of a triangle's exterior angle is the sum of the opposite interior angles of the exterior angle.
Which means :
∠36° + ∠x° = ∠(2x + 7)°Let us solve this equation to find the measure of the exterior angle :
[tex] =\tt 2x + 7 = 36 + x[/tex]
[tex] = \tt2x + 7 - x = 36[/tex]
[tex] =\tt x + 7 = 36[/tex]
[tex] = \tt \: x = 36 - 7[/tex]
[tex] =\tt x = 29[/tex]
Thus, the measure of ∠x = 29°Then, the measure of the exterior angle :
[tex] = \tt2 \times 29 + 7[/tex]
[tex] = \tt58 + 7[/tex]
[tex] = \tt65[/tex]
Thus, the measure of the exterior angle 2x+7 = 65°
Let us check whether or not we have found out the correct measure of each angle by placing 29 in the place of x:
[tex] = \tt2 \times 29 + 7 = 36 + 29[/tex]
[tex] =\tt 58 + 7 = 36 + 29[/tex]
[tex] = \tt65 = 65[/tex]
Since the measures match we can conclude that we have found out the correct value of each angle.
Therefore, ∠2x + 7° = 65°
if you bought a stock last year for a price of $120 and it has gone down 10% since then how much is the stock worth now
Answer:
$108
Step-by-step explanation:
Since $120 is divisible by ten, we can just simply do 120/10, which is twelve. So, 10% of $120 is $12. $120 - $12 = $108

Answer:
RST
Step-by-step explanation:
The question is asking you to complete the congruence statement. In a congruence statement, the corresponding angles must be in the same order they are in, in the first half of the statement. In the first triangle <M=79, <N=60, and <O=42. So the other half must be in this same order. In the other triangle <R=79, <S=60, and <T=52, which is why the answer is RST.

Belle borrowed $18.275 to buy a new car. The interest rate she agreed to pay is 5%. If she takes 5 years to pay back the loan, how much will she owe?
Answer:
$22843.75
Step-by-step explanation:
I'm assuming that $18.275 is $18,275
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 18275 × 0.05 × 5 = 4568.75
I = $ 4,568.75
The simple interest accumulated
on a principal of $ 18,275.00
at a rate of 5% per year
for 5 years is $ 4,568.75.
Answer:
$95943.75
Step-by-step explanation:
(assuming that its actually 18,275 and not 18.275)
18,275*1.05(5)
the amount borrowed (18,275)* the interest rate (1.05) *the number of years (5)
If the simple interest on $7,000 for 5 years is $2,800, then what is the interest rate?
Answer:
8%
Step-by-step explanation:
Solving our equation
r = 2800 / ( 7000 × 5 ) = 0.08
r = 0.08
converting r decimal to a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to
accumulate simple interest of $ 2,800.00
from a principal of $ 7,000.00
over 5 years is 8% per year.

a chord subtends an angle of 34 at the center of a circle of radius 4cm find the length of the chord (take =22/7)
Answer:
2.34 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle at the centre (θ) = 34°
Radius (r) = 4 cm
Length of chord (C) =?
The length of the chord can be obtained as follow:
C = 2rSine(θ/2)
C = 2 × 4 × Sine(34/2)
C = 8 × Sine 17
C = 8 × 0.2924
C = 2.34 cm
Therefore, the lenght of the chord is 2.34 cm.
Which one is the answer.
