Answer:
C, The marble is 3 times as likely to be black as it is to be white.
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong.
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong.
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct.
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.
What is the slope of the line given by the equation below?
y = 4x - 2
Answer:
As y=4x−2 can be written as y=4x+(−2) . Hence, it's slope is 4 and intercept on y -axis is −2
Solve the following inequality. 21 ≤ -3(x-4) < 30
Answer:
[tex]-6<x\leq -3[/tex]
Step-by-step explanation:
The process of solving inequalities like this is similar to the process of solving equations. Isolate the variable x, and whatever you do to one side, do to the other sides.
1) First, distribute the -3 to the terms inside the parentheses:
[tex]21\leq -3(x-4)<30\\21 \leq -3x+12< 30\\[/tex]
2) Next, subtract 12 from all three sides:
[tex]21 \leq -3x+12< 30\\9\leq -3x<18[/tex]
3) Finally, divide all three sides by -3. However, remember that whenever you divide numbers on different sides by a negative number, you need to flip the signs to make them face the other way:
[tex]9\leq -3x<18\\-3\geq x>-6[/tex]
Thus, [tex]-3\geq x>6[/tex] is the answer. Normally, answers are written with the numbers going from least to greatest, so you could also write it like this and it would still be correct, too:
[tex]-6<x\leq -3[/tex]
Answer:
C. -6 < x ≤ -3

yes a function is being represented
Step-by-step explanation:
in order for a graph to represent a function, the graph of a function f is the set of ordered pairs, where f(x) = y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

Which choice is the solution set for the inequality below , sqrt of x > 11 , I had put x>121 n got it wrong not sure what I need to do
Answer: Option B, x ≥ 121
Step-by-step explanation:
We start with the inequality:
√x ≥ 11.
First, we can square each side of the inequality, to get:
(√x)^2 ≥ 11^2
And we know that:
√(x^2) = (√x)^2 = x
Then:
x ≥ 11^2
x ≥ 121
So we only need to have x equal or larger than 121.
The correct option is B.

The vet told Casey that her dog should weigh at most 70 lbs. Her dog weighs 106 pounds, so Casey set a goal that he would lose 4 pounds per week. Which inequality represents the number of weeks it take for Casey's dog to reach 70 lbs?
Answer:
The inequality =
106 - 4x ≥ 70
The number of weeks =
9 weeks
Step-by-step explanation:
The vet told Casey that her dog should weigh at most 70 lbs. Her dog weighs 106 pounds, so Casey set a goal that he would lose 4 pounds per week. Which inequality represents the number of weeks it take for Casey's dog to reach 70 lbs?
Let the number of weeks for Casey's dog to lose for 4 pounds be represented as: x
The goal weight = 70 Ibs
Hence:
70 Ibs = 106Ibs - 4Ibs ×x
106 - 4x ≥ 70
4x ≥ 106 - 70
4x ≥ 36
x ≥ 36/4
x ≥ 9 weeks
It would take 9 weeks for Casey's dog to lose 4 pounds per week and weigh 70 Ibs
Therefore:
The inequality =
106 - 4x ≥ 70
The number of weeks =
9 weeks

There are 888 employees on The Game Shop's sales team. Last month, they sold a total of ggg games. One of the sales team members, Chris, sold 171717 fewer games than what the team averaged per employee. How many games did Chris sell? Write your answer as an expression.
Answer:
g/8 - 17
Step-by-step explanation:
Total number of employees = 8
Total games sold for last month = g
Average number of games sold per employee = Total games sold for last month / Total number of employees
= g / 8
Average number of games sold per employee = g/8
Chris sold 17 fewer games than what the team averaged per employee
How many games did Chris sell?
Number of games Chris sold = g/8 - 17
= g-136/8
= (g-136)/8
The expression which represent number of games Chris sold = g/8 - 17
Some female butterflies lay their eggs in clusters. If one kind of butterfly lays 12 eggs at a time and another kind lays 18 eggs at a time, how many eggs would 8 of each kind of butterfly lay? a 96 eggs b 144 eggs c 240 eggs d 200 eggs
Answer: 240 eggs
Step-by-step explanation:
The first kind of butterfly lays 12 eggs at a time. If there were 8 of them they would lay:
= 12 * 8
= 96 eggs
The second kind lays 18 eggs a time. 8 of them would lay:
= 18 * 8
= 144 eggs
Total number of eggs is:
= 96 + 144
= 240 eggs

Members of a soccer team raised $2158 to go to a tournament. They rented a bus for $1130.50 and budgeted $68.50 per player for meals. Write and solve an equation which can be used to determine xx, the number of players the team can bring to the tournament.
Answer: 15
Step-by-step explanation:
Let x = the number of players the team can bring to the tournament.
Given: Soccer team raised $2158 for tournament.
Bus rent = $1130.50 and budget per player for meals = $68.50
Total cost of tournament = Bus rent + (budget per player for meals) ( number of players the team)
[tex]2158=1130.50+68.50x\\\\\Rightarrow\ 68.50x=2158-1130.50\\\\\Rightarrow\ 68.50x=1027.5\\\\\Rightarrow\ x=\dfrac{1027.5}{68.5}\\\\\Rightarrow\ x=15[/tex]
Hence, the number of players the team can bring to the tournament = 15

A taxi driver records the time required to complete various and the distance for each trip. The best-given fit line by the equation y=0.467x + 0.417, where y represents the distance miles, and x represents the time for the trip in minutes. Estimate the distance for a trip that takes 20 minutes, show your reasoning
Using the line of best fit, it is found that the estimated distance for a trip that takes 20 minutes is of 9.757 miles.
What does the line of best fit gives?It gives the estimated distance in miles of a trip that takes x minutes, according to the following function?
y = 0.467x + 0.417.
In this problem, the trip took x = 20 minutes, hence the distance is given by:
y = 0.467 x 20 + 0.417 = 9.757 miles.
