The relationship between two quantities that increase or decrease together is called A. indirect variation B. variation C. indirect option D. direct variation E. direct option
Answer:
D. direct variation
Step-by-step explanation:
Answer:
yes it is direct variation
Step-by-step explanation:
well I'm sorry I Don't know if it's going to be step by step but my own understanding is that what ever happens on one side will affect the other side so if there is an increase in A there will be an increase in B so there's a form of equilibrium. so let's say we throw two stones A and B into a fast flowing river we expect that the water will flow so the more the velocity of the river the faster the stone will flow so as the river is flowing the stone is floating as well but an indirect variation as the river increases it's velocity the stone decreases it's movement so in direct variation as the river increases it's velocity the stone does as well. I hope this is well detailed and I answered your question , thank you

What is the volume of a cylinder, in cubic cm, with a height of 8cm and
a base diameter of 14cm? Round to the nearest tenths place
Answer:
Volume of the cylinder is 1232 cubic cm.Step-by-step explanation:
Given that:
A cylinder of height 8 cm and a base diameter of 14 cm.To Find:
What is the volume of a cylinder, in cubic cm.We know that:
Volume of a cylinder = πR²hWhere,
π = Ratio of circumference is to diameter = 22/7R = Base radius = 14/2 = 7 cmh = Height of the cylinder = 8 cmFinding the volume:
⟶ Volume = 22/7 × (7)² × 8
⟶ Volume = (22 × 7 × 7 × 8)/7
⟶ Volume = 8624/7
⟶ Volume = 1232
Hence,
Volume of the cylinder is 1232 cubic cm.Determine the direction that this parabola

PLEASE I NEED HELP ASAP!!
Answer:
Option C
Step-by-step explanation:
System of equations have been given as,
y - 4x = 16
y = 4x + 16 ------(1)
By comparing with slope-intercept form of the linear equation,
y = mx + b
Here, m = slope of the line
b = y-intercept
Therefore, m₁ = 4
2y = 8x + 16
y = 4x + 8 -------(2)
Slope of the line m₂ = 4
m₁ = m₂
Therefore, both the lines are parallel and both will not intersect each other.
Hence, there will be no solution of the system of equations.
Option C will be the correct option.

For one month, 500 elementary students kept a daily record of the hours they spent watching television. The average number of hours per week spent watching television was 28. The researchers conducting the study also obtained report cards for each of the students. They found that the students who did well in school tended to spend less time watching television than those students who did poorly. Listed are several possible statements concerning the results of this research. Place a check by every statement that you agree with based on this study.
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
b. If a student decreased the amount of time spent watching television, his or her performance in school would improve.
c. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
d. One month is not a long enough period of time to estimate how many hours the students really spend watching television.
e. I don't agree with any of these statements.
Answer:
a. The sample of 500 is too small to permit drawing conclusions about elementary students in general.
C. Even though students who did well in school watched less television, this doesn't necessarily mean that watching television hurts school performance.
Step-by-step explanation:
To make inferences about a general population from sample data, we must ensure that the data is considerably large enough and randomized, this is in other to ensure that the sample is representative of the population. Hence, Making conclusion about a very large population such as here, where we want to correlate performance and playing time, a very large sample which should be atleast 10% of the population should be employed. Hence, a sample of 500 ; for making Decison about general elementary students which should run into millions require more samples.
Also Recall that, correlation does not imply causation, The fact that there is a perceives relationship between grade or performance and time spent watching TV does not necessarily mean that poor grade was caused by long duration of hours spent watching television. Other, factors such as, level of intelligence, variation of teachers competence and so on may also be causal factors.

Answer:
3152 cm²
Step-by-step explanation:
Applying,
A = bh+(a+b+c)L................... Euqation 1
Where A = surface area of the triangular prism, a, b, c are the length of the three side of the triangule respectively, L = Length of the prism, h = height of the triangle.
From the question,
Given: a = 25 cm, c = 25 cm, b = 14 cm, h = 24 cm, L = 44 cm
Substitute these values into equation 1
A = 14×24+(25+25+14)44
A = 336+2816

Answer:
45 degrees
opposite angles are the same so
30+30=60
105+105=210
210+60=270
360-270=90
but since we have 2 angles we divide it by 2
so angle 1 is 45 degrees

Voce 2x-u - 1x2-3x+3 = 2
Answer:
u=−x2−x+1
Step-by-step explanation:
Let's solve for u.
2x−u−1x^2−3x+3=2
Step 1: Add x^2 to both sides.
−x2−u−x+3+x2=2+x2
−u−x+3=x2+2
Step 2: Add x to both sides.
−u−x+3+x=x2+2+x
−u+3=x2+x+2
Step 3: Add -3 to both sides.
−u+3+−3=x2+x+2+−3
−u=x2+x−1
Step 4: Divide both sides by -1.
−u/−1=x2+x−1
−1/u=−x2−x+1
Answer:
u=−x2−x+1

Step-by-step explanation:
An anthropologist wishes to estimate the average height of men for a certain race of people. If the population standard deviation is assumed to be 2.8 inches and if she randomly samples 100 men, find the probability that the difference between the sample mean and the true population mean will not exceed 0.7 inch. (Round your answer to four decimal places.)
Answer:
The probability that the difference between the sample mean [tex]\bar{x}[/tex] and the true population mean [tex]\mu[/tex] is : [tex]P[|\bar{x}-\mu|\leq0.7]=0.9876[/tex]
Step-by-step explanation:
Given :
Population standard deviation [tex]\sigma=2.8[/tex].
Sample size [tex]n=100[/tex]
The sample mean standard deviation[tex]=\frac{\sigma}{\sqrt{n}}[/tex]
To find :
The probability that the difference between the sample mean [tex]\bar{x}[/tex] and the true population mean [tex]\mu[/tex]
[tex]\because\frac{\sigma}{\sqrt{n}}=\frac{2.8}{\sqrt{100}}=\frac{2.8}{10}=0.28[/tex]
Now, the probability that the difference between the sample mean [tex]\bar{x}[/tex] and the true population mean [tex]\mu[/tex] is :
[tex]P[|\bar{x}-\mu|\leq0.7][/tex], [tex]n[/tex]is large [tex]\Rightarrow \frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}=z[/tex]
[tex]\Rightarrow P[\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}<\frac{0.7}{\frac{\sigma}{\sqrt{n}}}]=P[z<\frac{0.7}{0.28}]=P[z<2.5][/tex]
[tex]\Rightarrow P[z<2.5]=P[-2.5<z<2.5][/tex]
[tex]\Rightarrow P[-2.5<z<2.5]=P[z<2.5]-P[z\leq-2.5]\\\Rightarrow P[z<2.5]-P[z\leq-2.5]=2P[z\leq2.5]-1\\\Rightarrow 2P[z\leq2.5]-1=0.9876[/tex]
Therefore, the probability [tex]P[|\bar{x}-\mu|\leq0.7]=0.9876[/tex]
What is the area, in square inches, of the triangle? A =1/2bh
Answer: 24 in.²
Step-by-step explanation: Since the base of the triangle has a length of 8 inches and the height of the triangle has a length of 6 inches, the area of the triangle is 1/2(8)(6) or 1/2(48) which is 24.
So the area of this triangle is 24 in².
Answer:
24 in^2
Step-by-step explanation:
Plug known values into the equation for triangle area: [tex]A=\frac{bh}{2}[/tex] and solve.
Another way to think of this is to multiply the base value and height value together (which is how you get area of a rectangle) and divide by two because triangles are essentially rectangles cut in half.

PLZ ANSWER WORTH 20 POINTS!! URGENT!
A set of equations is given below: Equation C: y = 3x + 7 Equation D: y = 3x + 2 Which of the following best describes the number of solutions to the given set of equations? (1 point) A. One solution B. Two solutions C. Many solutions D. No solution
Answer:
D. No solution
Step-by-step explanation:
Given
[tex]y = 3x + 7[/tex]
[tex]y = 3x + 2[/tex]
Required
The number of solutions
We have:
[tex]y = 3x + 7[/tex] and [tex]y = 3x + 2[/tex]
Equate both i.e.
[tex]y = y[/tex]
So, we have:
[tex]3x + 7 = 3x + 2[/tex]
Subtract 3x from both sides
[tex]3x -3x + 7 = 3x -3x + 2[/tex]
[tex]7 = 2[/tex]
The above is false
i.e. [tex]7 \ne 2[/tex]
Hence, the system has no solution
