probability (a) = 25%
probability (b) = 60%
determine probability (a and b)
Answer:
85%
Step-by-step explanation:
P(a) = 25%=1/4
P(b) = 60%=3/5
P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%
Answer:
The probability of A and B is 85%
Step-by-step explanation:
It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

Answer:
[tex](a-b)(a+c)[/tex]
Step-by-step explanation:
Factor each half of the expression separately:
[tex]a^2-ba+ac-cb\\a(a-b)+c(a-b)[/tex]
Since both a and c are being multiplied by a-b, we can combine them to get:
[tex](a-b)(a+c)[/tex]

A 440 wire is cut into three pieces the second piece is two times as long as the first the third piece is four times as long as the second how long is each piece
Step-by-step explanation:
[tex]x \: as \: the \: first \: piece \\ 2x \: as \: the \: second \: piece \\ 4(2x) = 8x \: as \: the \: third \: piece[/tex]
[tex]x + 2x + 8x = 440 \\ 11x = 440 \\ x = \frac{440}{11} \\ x = 40 \\ 2x = 2 \times 40 = 80 \\ 8x = 8 \times 40 = 320 [/tex]

Answer:
x = ln (y)
Step-by-step explanation:
There's two main ways to solve this. When there is no logarithm in the equation you can either take the log of both sides OR change an exponential equation to logarithmic form.
See image.
note: log_2 (2) = 1
log_3 (3) = 1
log_4 (4) = 1
log_5 (5) = 1
if the base and the article are the same then it equals 1
ln e = 1
because ln e means the same thing as log_e
log_e (e) = 1
e is just a number!
If you are changing exponential form to logarithmic form, the base is the same in both forms. The base is the base. The base in exponential form is the base in logarithmic form. The base is the base. The exponent and article basically switch places to change forms.

how does the graph of g(x) = (x - 3)^3 - 2 differ from the group of f(x) = x^3?
A. g is shifted 3 units right and 2 units up.
B. g is shifted 3 units right and 2 units down.
C. g is reflected across the y-axis.
D. g is rotated 90* clockwise.
Answer:
B
Step-by-step explanation:
f(x) = x³
g(x) = (x - 3)³ - 2
The inside of the parenthesis represents a horizontal shift
If the number operation being done to x inside of the parenthesis is adding ( or if the number is positive ) then the graph will shift to the left. If the operation being done inside of the parenthesis to x is subtraction ( or if the number is negative ) then the graph will shift to the right.
The operation being done is subtraction therefore it will shift to the right. So it will go 3 units to the right.
the number on the outside works like a y intercept. if it's positive it goes up, if it's negative it goes down. the number is -2 so it will go down 2 units
we can conclude that g is shifted 3 units right and 2 units down
the answer is B

2. One bag of fertilizer will cover 400 square feet. Find how many bags should be purchased to cover a garden that is
35 feet by 75 feet.
35*75 is
2625
2625/400 is
6.5625
Since you cannot have a decimal amount of a bag, you should purchase
(rounding)
7 bags of fertilizer
Answer:
7 bags
Step-by-step explanation:
First thing you need to do is figure out the area of the garden. Area=length×width, so just put in your numbers, 35×75=2625 square feet. One bag covers 400 feet, so you divide the area by 400, 2625÷400=6.5625. You can't buys 6.5625 bags of fertilizer, so you have to go up to the next whole number which is 7.

A bicycle wheel has a circumference of 62 inches. Find the diameter of the wheel. If necessary, round to the tenths place. 39. 5 inches 19. 7 inches 15. 5 inches 9. 9 inches.
Answer:
19.7 inches
Step-by-step explanation:
circumference of a circle = 2πr
62 = 2*22/7 *r
r = 62 * 7 / 44 = 9.86
diameter = 2* r
= 2* 9.86
= 19.7 inches

Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
• Principal (P) = Rs.57,000
• Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
• Time (n) = 4 years
Applying Interest formula,
[tex]→In=P \times R \times T[/tex]
[tex]→57,000 \times 0.06 \times 4[/tex]
[tex]→Rs.13680[/tex]
Hence, the interest is Rs.13680
An angle measures 52.8 degrees more than the measure of its supplementary angle. what is the measure of each angle?
Answer: 116.4 and 63.6 degrees
Step-by-step explanation:
Let the angle be x, so supplement is 180-x.
This means x - 52.8 = 180 - x
2x = 232.8
x = 116.4
So the angle measures are 116.4 and 63.6 degrees
