Answer:
B. Two dependent samples are compared
Step-by-step explanation:
We use it when we are comparing Two dependent samples. The paired t-test can be likened to the repeated measures ANOVA test. Both of these two test are useful when comparing how a static group does in different test conditions.
But the difference between these two are:
We use the paired t-test if the explanatory variable has two levels.
While the Repeated measures ANOVA is used when the explanatory variable has greater than two levels.
6(a+4)=72
Help please
Answer:
a = 8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(a+4)=72
(6)(a)+(6)(4)=72(Distribute)
6a+24=72
Step 2: Subtract 24 from both sides.
6a+24−24=72−24
6a=48
Step 3: Divide both sides by 6.

A triangle is shown on the right. What is the measure of the missing angle of the triangle? (Please leave a small explanation)
Answer:
it's answer is D. 33°
Step-by-step explanation:
Let the unknown angle be x Then.
x + 100° + 47° = 180° [ being sum of angles of triangle ]
x + 147° = 180°
x = 180° - 147°
x = 33°

Suppose there are 50 possible dancers. How many trios may be formed, assuming the order within a trio does not matter
Answer:
19600 trios may be formed.
Step-by-step explanation:
Since the order of the trios do not matter, we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
Groups of three(Trios) from a set of 50. So
[tex]C_{50,3} = \frac{50!}{3!(50-3)!} = 19600[/tex]
19600 trios may be formed.

Answer:
The equation of the line is:
[tex]y = 3x+3[/tex]
The graph is also attached.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptFrom the straight line on the graph, taking two points
(0, 3)(-1, 0)Finding the slope between (0, 3) and (-1, 0)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [0 - 3] / [-1 - 0]
= -3 / -1
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 3
Thus, the y-intercept b = 3
Now, substituting slope m = 3 and y-intercept b = 3 in the slope-intercept form
y = mx+b
y = 3x+3
Therefore, the equation of the line is:
[tex]y = 3x+3[/tex]
The graph is also attached.
Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.
Please see the picture
Help
Answer:
286.97
Step-by-step explanation:
find the area of the rectangle first
14*15=210
Next
Find the area of a circle
πr^2=a
the radius of the circle is half the height of the rectangle
π*(7*7)=a
a=153.94
Now
Divide the area by two
153.94/2=76.97
Now add the two areas
76.97+210
Answer:
Area of the figure= area of the rectangle+ area of the semicircle
=(15×14)+(1/2)π(7)²=210+77=287 square unit
287 square unit is the right answer.
Remember:--- area of the rectangle
=(length×breadth)
and area of the semicircle=π(radius)²/2
You deposit $572.34 into a account that pays 4.5% interest.How much interest do you earn after 60 months
Plz show work
Step-by-step explanation:
assuming it's 4.5% a year
572.34/100= 5.72
5.72×4.5=25.74 (per year)
60/12=5(years)
5×25.74= 128.7
128.7+572.34=701.04
You earn 128.7 dollars in interest and have 701.04 dollars at the end of 6 months

Consider the monthly payment formula M=Pr(1+r)^n/(1+r)^n-1. what is the name of the formula you get if you solve for P? what about if you solve for n? what special function do you need to use when solving for n?
WRITTEN RESPONSE QUESTION PLEASE ANSWER ASAP WILL AWARD BRAINLIEST.
Answer:
0.0061
Step-by-step drip check:
The name of the formula you get if you solve for P could be "Principal (loan amount)" "Term of the loan (in months)" or "Number of monthly payments"
Logarithms;
[tex]n = \dfrac{ ln[1 - \dfrac{Pr}{M} ]}{ln(1+r)}[/tex]
What is Monthly Payment Formula?Consider the monthly payment formula
[tex]M= \dfrac{Pr(1+r)^n}{(1+r)^n-1}[/tex]
where: M = monthly payment.
P = principal loan amount.
r = interest rate per month (in decimal form).
n = term of the loan (in months).
If we will solve for P, the name of the formula is "Principal (loan amount)".
If we solve for n, the formula is "Term of the loan (in months)" or "Number of monthly payments".
When solving for n, we have to use logarithms:
[tex]M (1+r)^n-1=Pr(1+r)^n\\\\\dfrac{1}{ (1+r)^n} = 1 - \dfrac{Pr}{M} \\\\ln\dfrac{1}{ (1+r)^n} = ln[1 - \dfrac{Pr}{M} ]\\\\\\n = \dfrac{ ln[1 - \dfrac{Pr}{M} ]}{ln(1+r)}[/tex]

The graph at left in the tc-plane models the global wind power capacity, c, in gigawatts, t years since 1996. What is the best interpretation of the c-intercept of this graph?
The image shows an exponential curve graphed in the first quadrant of the 't c'-plane. The horizontal 't'-axis is labeled Years since 1996 and the vertical 'c'-axis is labeled Global wind power capacity (gigawatts). The graph crosses the 'c'-axis at about 7 and increases exponentially, passing roughly through the point (13 comma 150).
9514 1404 393
Answer:
c(0) = 7 means global wind power capacity was 7 GW in 1996
Step-by-step explanation:
The c-intercept is the global wind power capacity at t=0, which was in 1996. The scale is in gigawatts, so c=7 at t=0 means ...

Tom paid $0.60 per pound for tomatoes to sell at his produce store. He added a 33% markup. What price did he charge his customers for the tomatoes? Round to the nearest cent if needed.
Tom is charging $0.8 per pound to his customers.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Given that,
Tom paid $0.60 per pound for tomatoes to sell at his produce store.
So,
Cost of tomatoes = $0.60/pound
Now,
33% of 0.60 ⇒
33 × 60 /100 = $0.198
So final price ⇒
0.60 + 0.198 = 0.798
By rounding the nearest tenth
⇒ $0.8/pound.
Hence "Tom is charging $0.8 per pound to his customers".

On a game show, a contestant randomly chooses a chip from a bag that contains numbers and strikes. The theoretical probability of choosing a strike is 3/10. The bag contains 9 strikes. How many chips are in the bag?
Answer:
30
Step-by-step explanation:
If the probability of choosing a strike is 3/10, that means that from the total items available 3 out of 10 are strikes, now, if there are 9 strikes total, this is the equation representing such result:
(3/10)(totalChips) = 9
if we solve for totalChips we have:
3(totalChips) = 9*10 = 90
totalChips = 90/3 = 30
