The sixth-grade class was asked the question, “What job would you like the best?” The results are shown in the table. What percent of the sixth-grade class said that they would like to be a movie director?
A) 23%
B) 31%
C) 41%
D) 45%
The percent of the sixth-grade class that said they would like to be a movie director is A. 23%.
How to calculate the percentage?It's important to note that a percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
In this case, the sixth-grade class was asked the question, “What job would you like the best and the results are shown in the table.
.
The. total number will be:
= 84 + 92 + 124 + 100
= 400
The percent of the sixth-grade class that said they would like to be a movie director will be:
= Movie director / Total number × 100
= 92/400 × 100
= 23%

(-4,19) (0,3) whats the slope?
Answer:
m= -4
Step-by-step explanation:
Slope is equal to the change in y over the change in x
, or rise over run.
m=change in ychange in x
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1
Substitute in the values of x
and y
into the equation to find the slope.
m=3−(19)0−(−4)

Find the area of a triangle with sides of length 7 and 9 and included angle 72 degree.
Answer:
A = 29.96
Step-by-step explanation:
Area of a triangle
Side Angle Side (SAS) Method :
Given a triangle with two known sides a and b, and their included angle C, the area can be calculated as follows:
[tex]\displaystyle A=\frac{a.b.\sin(C)}{2}[/tex]
The triangle has sides of lengths a=7 and b=9 and their included angle is C=72°. Substituting:
[tex]\displaystyle A=\frac{7\cdot 9.\sin(72^\circ)}{2}[/tex]
A = 29.96

A consumer group is investigating the number of flights at a certain airline that are overbooked. They conducted a simulation to estimate the probability of overbooked flights in the next 5 flights. The results of 1,000 trials are shown in the following histogram.
Answer:
C. 0.446
Step-by-step explanation:
1-(0.114+0.332) = 0.446
The sum of the relative frequencies of the bars for 4 and 5 is 0.446.
The probability that atleast four of the next five flights will be overbooked is the sum of the probabilities of having 4 or 5 flights overbooked which is 0.446
The probability of having atleast 4 flights overbooked can be defined as :
P(X ≥ 5) = P(X = 4) + P(X = 5)
From the probability distribution displayed on the histogram :
P(X ≥ 5) = 0.332 + 0.114 = 0.446
Therefore, the probability of having atleast 4 flights overbooked ls 0.446

Rodney wants to buy a camera that costs $133. This amount is $25 more than 3 times the amount he saved last month. Which equation could be used to solve for x, the amount Rodney saved last month?
Answer: 25+3x =133
Step-by-step explanation:
Let x = the amount Rodney saved last month
Cost of camera Rodney wants to buy= $133 , which is $25 more than 3 times the amount he saved last month.
i.e. 25+3(amount Rodney saved last month) = Cost of camera (in dollars)
i.e. 25+3x =133 (in dollars)
Hence, the equation could be used to solve for x : 25+3x =133

x^2 plus 2y divideed by 2x plus 3z equal
Answer:
(x^2 plus 2y")
--------------------
2x(2x + 3)
Step-by-step explanation:
Doing this problem correctly requires the application of "order of operations" rules. "x^2 plus 2y" actually means "(x^2 plus 2y"), and so your
x^2 plus 2y divided by 2x
comes out to:
(x^2 plus 2y")
--------------------
2x
If we now divide this result by "2x plus 3z," we get:
(x^2 plus 2y")

Step-by-step explanation:MARK BRAINLIEST I NEED 1 MORE
Using the divisibility rules, 678 is divisible by 2, 3, and 6.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We need ot find that 678 is divisible by 2, 3, and 6.
WE can see 678 is even, so it's divisible by 2
Now, the sum of digits are 6+7+8 = 21, which is divisible by 3, so 678 is divisible by 3
Since 678 is divisible by both 2 and 3, then it has to be divisible by 6
Using the divisibility rules, we can conclude that 678 is divisible by 2, 3, and 6.

Will Name BRAINLIEST!!!
Answer:
time greater than 6 hours
Step-by-step explanation:
For this problem, we are given the rate at which the refrigerator's temperature increases and the rate at which the oven's temperature decreases along with the initial temperatures for both. Using this information, we can determine the amount of time that will need to pass for the two to have equal temperature, or pass each other in opposite directions of temperature. Let's write the inequality using the information:
40 + 5t > 340 - 45t
Let t be the amount of time passed in hours. So, we simply need to solve the inequality for t.
40 + 5t > 340 - 45t
40 + 50t > 340
50t > 300
t > 6
Given this information, we know that after 6 hours have passed, the temperature of the fridge and oven will be equal. So we can say that any time greater than 6 hours, the fridge will have a higher temperature than the oven.
