Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x=63 . Which of these statements are true? Choose ALL that are correct. A Robert's sales are represented by x when solving 3.5x=63 . B Robert's sister's sales total $18.00. C Robert's sales are represented by x when solving 2.6x=63 . D Robert's sales total $25.20. E Robert's sister's sales are represented by x when solving 3.5x=63 .
Answer:
B. Robert's sister's sales total $18.00.
E. Robert's sister's sales are represented by x when solving 3.5x = 63 .
Step-by-step explanation:
Let
Robert sister's sales = x
Robert sales = 2.5 * x
= 2.5x
Total sales = Robert sister's sales + Robert sales
63 = x + 2.5x
63 = 3.5x
Divide both sides by 3.5
x = 63 ÷ 3.5
= 18
x = $18.00
Robert sales = 2.5x
= 2.5(18)
= $45.00
A. Robert's sales are represented by x when solving 3.5x=63 .
No
B. Robert's sister's sales total $18.00.
Yes
C. Robert's sales are represented by x when solving 2.6x=63 .
No
D. Robert's sales total $25.20.
No
E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:
This is the answer because:
1) Mean - add all the numbers and divide by with how many numbers you added.
2) The numbers are: 7,9,10,5,8,3,7
3) 7 + 9 + 10 + 5 + 8 + 3 + 7 = 49
4) 49 ÷ 7 = 7
Therefore, the answer is 7.

-3/8(x-24)+x=19 i need a answer ASAP!
Answer:
x = 16
Step-by-step explanation:
Problem: -3/8(x-24)+x=19
Distribution:
-3/8x + 9 + x = 19
5/8x = 19 - 9
5/8x = 10
x = 10 • 8/5
x = 16
Which equation could be used to solve for a value, x, that is equal to 5 times the sum of x and 12?

Answer:
The coordinates of point P are (1, -1)
Step-by-step explanation:
If the point (x, y) reflected about the x-axis, then its image is (x, -y)To find the image of a point reflected about the x-axis change the sign of its y-coordinateThe rule is R x-axis → (x, -y)If the point (x, y) reflected about the y-axis, then its image is (-x, y)To find the image of a point reflected about the y-axis change the sign of its x-coordinateThe rule is R y-axis → (-x, y)→ Assume that the coordinates of point P are (x, y)
∵ The coordinates of point P are (x, y)
∵ The rule of the reflection is R y-axis (P)
∴ Its image = (-x, y)
∵ The image = (-1, -1)
→ Equate the two images
∴ (-x, y) = (-1, -1)
∴ -x = -1
→ Divide both sides by -1
∴ x = 1
∵ y = -1
∴ The coordinates of point P are (1, -1)

Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00
Step-by-step explanation:
Let,
x be the price of one cheap golf ball
y be the price of one expensive golf ball
According to given statement;
6x+4y=12.50 Eqn 1
4x+3y=9.00 Eqn 2
Multiplying Eqn 1 by 4
4(6x+4y=12.50)
24x+16y=50.00 Eqn 3
Multiplying Eqn 2 by 6
6(4x+3y=9.00)
24x+18y=54.00 Eqn 4
Subtracting Eqn 3 from Eqn 4
(24x+18y)-(24x+16y)=54.00-50.00
24x+18y-24x-16y=4.00
2y=4.00
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{4.00}{2}\\y=2.00[/tex]
Putting y=2.00 in Eqn 1
6x+4(2.00)=12.50
6x+8.00=12.50
6x=12.50-8.00
6x=4.50
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{4.50}{6}\\x=0.75[/tex]
Hence,
Cost of one cheap golf ball is $0.75 and one expensive golf ball is $2.00

Mike has a certain amount of money and is given $25.25 more money. Anthony has three times the total that mike has plus $5.48 extra dollars. Their combined total is $261.23. Write an equation and solve it to determine how much each of them has.
Answer:
Mike has =$63.94
Anthony = $197.3
Step-by-step explanation:
Step one:
let the certain amount that Mike has be x
so
in all Mike has = (x+25.25)
Anthony has
3(x+25.25)+5.48
we are told that the total amount for both Mike and Anthony is
$261.23
so
(x+25.25)+3(x+25.25)+5.48=261.23
open bracket
x+25.25+3x+75.75+5.48=261.23
collect like terms
x+3x+25.25+75.75+5.48=261.23
4x+106.48=261.23
4x=261.23-106.48
4x=154.75
divide both sides by 4
x=154.75/4
x=38.69
Hence,in all
Mike has = (38.69+25.25)
Mike has =$63.94
Anthony has
=3(38.69+25.25)+5.48
=3(63.94)+5.48
=191.82+5.48
=$197.3

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount.
What is the cost in dollars and cents for each video game?
PLZZZZ HELP
Answer:
I would say it's $23.98
Step-by-step explanation:
If you do 100-4.08, you get 95.92 and since there's 4 video games, divide 95.92 by 4 and you get 23.98
Answer:
$23.98 or 2398 cents
Step-by-step explanation:
If the cashier gave $4.08 back, that means that he spent 100-4.08 on the 4 games.
$100 = 4 games + $4.08
4 games = $95.92
$95.92/4 = $23.98

1. Calculate the value of x in the following diagram. 53 - Y IN Q 5x 18
Answer:
x = 7
Step-by-step explanation:
QY = 5x
YZ = 18
QZ = 53
Thus:
QY + YZ = QZ (segment addition postulate)
5x + 18 = 53
5x = 53 - 18 (subtraction property of equality)
5x = 35
Divide both sides by 5

Paul is locked out of his house. An 18-ft ladder is outside and an upstairs window is open. Paul read the safety warning on the ladder recommending it be placed six feet away from the wall. He placed the ladder according to the warning and it reached the base of the window. How high is the base of the window off the ground?
Answer:
17.0 ft
Step-by-step explanation:
Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.
So, using Pythagoras' theorem,
L² = h² + d²
So, h = √(L² - d²)
Substituting the values of L = 18 ft and d = 6 ft, we have
h = √((18 ft)² - (6 ft)²)
= √(324 ft² - 36 ft²)
= √288 ft²
= 16.97 ft
≅ 17.0 ft
