Answer:
Question 5: The missing term her is r²
Question 6: The missing term here is 3.
Step-by-step explanation:
Question 5:
Let's write the equation and then solve it for the missing term. We will call this term x.
[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]
First, we simplify the letf term adding the similar terms.
[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]
Now, we substract 4r⁴ and 7r in both sides.
[tex]x=r^{2}[/tex]
Therefore, the missing term her is r²
Question 6:
Here, we will call the missing term y. Now, let's solve it for y.
[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]
Let's first distribute the minus sign into the parentehsis.
[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]
Now simplify the left side by adding similar terms.
[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]
Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.
[tex]y=10-7[/tex]
[tex]y=3[/tex]
Therefore, the missing term here is 3.

Natalie's aunt gave her $47 to spend on clothes at the mall. She bought 4 shirts that cost $4 each and a pair of pants that cost $13. How much money does Natalie have left to buy more clothes?
Answer:$18
Step-by-step explanation:4 * 4 = $16. One pair of pants = $13. 16 + 13 = $29. 47 - 29 = $18
Which is the equation of a parabola with vertex (0,0) and directrix y= 4
a. Y^2 = -8x
b. Y^2 = -16x
c. X^2 = -8y
d X^2 = -16y
Answer:
D. [tex]x^{2} = -16\cdot y[/tex]
Step-by-step explanation:
The vertex form of the equation of the parabola centered in the origin, with axis of symmetry in the x-axis and directrix in the first and second quadrants is described by the following formula:
[tex]4\cdot p \cdot y = x^{2}[/tex], [tex]p < 0[/tex] (1)
Where:
[tex]y[/tex] - Dependent variable.
[tex]x[/tex] - Independent variable.
[tex]p[/tex] - Focus distance.
If we know that vertex is located at (0, 0) and the directrix pass through (4, 0), then the focus distance (distance of the vertex with respect to that point) is -4, and the equation of the parabola is [tex]x^{2} = -16\cdot y[/tex].
Hence, the right choice is D.

Find the probability that a student is not playing a sport or not taking a foreign
language using the Venn Diagram below.
Answer:
18/25
Step-by-step explanation:
Total number of students = 23+14+10+3 = 50.
14 out of 50 are playing sport and taking a foreign language.
So the answer is (50 - 14) / 50
= 36/50
= 18/25.
=========================================================
Explanation:
The wording your teacher provided is a bit strange in my opinion. Though I think they are referring to the people who aren't taking both classes at the same time, but they could be taking exactly one class.
We have 23+14+10+3 = 50 students total and 14 of them are taking both classes. So 50-14 = 36 students are taking exactly one class, or they are taking neither of the classes.
This leads to a probability of 36/50 = (2*18)/(2*25) = 18/25 which points to choice B as the answer.
------------------
Side note:
If it asked "what is the probability that a student is not taking a sport AND not taking a foreign language?", then the probability would be 3/50 because there are 3 people not taking either class out of the 50 total. So the keyword "and" is the change made here, instead of the "or".
Shane hit the ball 3 out of times. How is this written as a ratio?
Question is incomplete as number of trials isn't given. We'll use an hypothetical value to make x plain the situation
Answer:
Kindly check explanation
Step-by-step explanation:
Given that the number of trials = x
If the number of tines the ball was hit out if 'x' trials = 3
The ratio of the number of hits to the number of trials is written as :
Number of hits : Number of trials
3 : x
Just put the exact value of x in the equation above and if possible, reduce to simplest form.

The value of y varies directly with x. When y=75, x= 0.5. What is the value of y when x is 2.25?
Even though I pulled up the work, I still don’t know what to do ♀️
Answer:
y=337.5 when x = 2 1/4
Step-by-step explanation:
Well first we want to know what's the function here
How do we get y to be 75 if x is .5?
75/.5 is 150
so can we say the function is 150x=y
Now lets plug
2 1/4 or 2.25 for x
2.25*150 = 337.5
y=337.5 when x = 2 1/4
Hope that helps!

if the polygon is a decagon, then it has ____sides?
Answer:
10 sides
Step-by-step explanation:

A restaurant owner wants feedback on the items on the menu, so she leaves a customer satisfaction survey on the tables for customers to
complete if they wish. Which sampling method best describes this scenario?
O A) convenience sample
OB) simple random sample
O C) stratified random sample
OD) voluntary response sample
Answer:
O A) convenience sample
Step-by-step explanation:
O A) convenience sample
The sampling method which describes the situation is option D. voluntary response sample.
What are Sampling Methods?Sampling methods are methods used to select a sample using specific methods. This includes various types of probability sampling and non probability sampling methods.
This is included in the non probability sampling methods.
So it is either convenience sample or voluntary response sample.
Convenience sample is the selection of a sample which is convenient for you. That is, the sample which is most accessible is selected by the researcher.
Voluntary response sample is also the one which is most accessible. But the researcher is not selecting the sample. Instead the members of the population can decide whether to took part in the sample.
Here it is customer's wish to complete the survey.
So it is voluntary response sample.
Hence the correct option is D. voluntary response sample.

In a lottery, the top cash prize was $615 million, going to three lucky winners. Players pick four different numbers from 1 to 59 and one number from 1 to 49 . A player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 59 ) and matching the number on the gold ball (1 through 49 ). What is the probability of winning the minimum award?
Answer:
10063571 out of 593750689 or 1.69491525424%
Step-by-step explanation:
To find probability when all variables are known, you can just multiply the numbers you need. In this case we multiply 59 * 59 * 59 *49 since these are the balls we are picking from. We can find the chance of the top prize by multiplying all the numbers. 59 * 59 * 59 * 59 * 49

Rewrite the logarithmic equation: log4x = 5 in exponential form.
Answer:
4^5=x
x= 1045
Step-by-step explanation:
4 to the power of 5 is 1045:)
Answer:
The base of the log is the same as the base of the exponential form and in our case the base is 4. The value of the exponent is what the log is equal too and in our case it is 5. We already know the base is 4 and we want to raise it to the exponent of 5 so we get
x=45 *five on top*

The position of an object at time t is given by s(t) = -9 - 3t. Find the instantaneous velocity (by using the limit) at t = 8 by finding the derivative
Answer: [tex]v=-3[/tex]
Step-by-step explanation:
Given
The position of a particle is [tex]s(t)=-9-3t[/tex]
Velocity is given by the derivative of position with respect to time
[tex]\Rightarrow v=\dfrac{ds}{dt}\\\Rightarrow v=-3[/tex]
So, velocity is constant at any point in time.
At t=8, it is [tex]v=-3[/tex]
