Answer:
81
Step-by-step explanation:
To get the mean score, we have to add all their scores and divide the result by the number of members in the team.
(70+72+74+76+80+114) ÷ 6 = 486 ÷ 6 = 81
So, the answer is 81.

please help me please
Answer:
Step-by-step explanation:
Since they are similar we can say
(7x-13)/42=(x+5)/14 upon cross multiplication we have
14(7x-13)=42(x+5) divide each side by 14
7x-13=3(x+5) expanding right side
7x-13=3x+15 adding 13 to each side
7x=3x+28 subtracting 3x from each side
4x=28 dividing each side by 4
x=7

Researchers are investigating the effectiveness of leg-strength training on cycling performance. A sample of 7 men will be selected to participate in a training program that lasts for one month. Peak power during cycling will be recorded for each man both before training and after training. The mean difference in times will be used to construct a 95 percent confidence interval for the mean difference in the population.When all other things remain the same, which of the following statements about the width of the interval is correct?A) The interval will be narrower if 15 men are used in the sample.B) The interval will be wider if 15 men are used in the sample.C) The interval will be narrower if 5 men are used in the sample.D) The interval will be narrower if the level is increased to 99% confidence.E) The interval will be wider if the level is decreased to 90% confidence.

Slope=5/4 y intercept=2 write in slope intercept form then standard
Note:
Your first question is missing the y-intercept, so I am solving the 2nd question. You would still get your concept clear because the procedure to solve each of the questions is the same.
Answer:
The equation in the standard form is:
2/3x + y = -4
Please also check the attached graph.
Step-by-step explanation:
We know that the equation in the standard form is
Ax + By = C
where x and y are variables and A, B and C are constants
Given
Slope m = -2/3
y-intercept = -4
To determine
Write the equation in the standard form
We know that the slope-intercept form of the line equation
where
m is the slope
b is the y-intercept
In our case:
Slope m = -2/3
y-intercept = -4
substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation
y = mx+b
y = -2/3x + (-4)
y = -2/3x - 4
Writing the equation in the standard form
2/3x + y = -4
Therefore, the equation in the standard form is:
2/3x + y = -4

a triangle where one angle 120 degrees and another 50 degrees
I do not understand what you are asking for
I am assuming you want the missing angle, in this case it is 10

5. Alex mounts the clock on a wood
base with the shape shown at the
right. What is the area of the wood
base?
9514 1404 393
Answer:
487.2 in²
Step-by-step explanation:
The area of the semicircle is ...
A = (1/2)πr² . . . . . where r is half the diameter
A = (1/2)π(9 in)² = 40.5π in² ≈ 127.2 in²
The area of the rectangle is ...
A = bh
A = (18 in)(20 in) = 360 in²
Then the total area is ...
total area = semicircle area + rectangle area
= 127.2 in² +360 in² = 487.2 in² . . . . . area of the wood base
If a rectangle with length 6 cm and width 4 cm is enlarged by a scale factor of ½, then what is the perimeter of the new rectangle?
The perimeter of the new rectangle is 23cm
How to determine the perimeterFormula for perimeter is given by
Perimeter = 2(length + width)
Perimeter = 2( 6 + 4)
Perimeter = 2 × 10
Perimeter = 20cm
If the length and width are enlarged by 1/2, we have
Perimeter = 2( 6 + 4 +1/2)
Perimeter = 2( 10 + 0.5)
Perimeter = 2× 11. 5 = 23cm
Thus, the perimeter of the new rectangle is 23cm

Can someone please help me with math
Answer:
3. B
4. D
Step-by-step explanation:
3. The y-intercept is -4 and the slope is positive 2.
4.Substitute the values and check
Answer and Step-by-step explanation:
3.
Before we look at the answer choices, lets analyze the graph.
We see that as the graph goes right, the y values are positive, and that as the graph goes left, the y values become negative/decrease. (Graph, as in the line on the graph).
That means the graph has a positive slope. So we can get rid of any negative slopes (answer choices A and C).
Now, we look to see the rate of change of the graph. How many units does the graph go up and right right?
We see that the graph has a rate of change of 2, so that is the slope.
This means that answer choice B is the answer. The equation shows that it goes down 4 units as well, which is what the graph shows as well.
4.
For this one, we need to see the pattern in the table.
When we put 2 in for n, we get 6. When we put 3 in for n, we get 8. And when we put 4 in for n, we get 10.
Answer choice D works for this. If we plug 2, 3, and 4 in for this expression, we get:
2(2) + 2 = 4 + 2 = 6
2(3) + 2 = 6 + 2 = 8
2(4) + 2 = 8 + 2 = 10
So answer choice D is the answer.

Step-by-step explanation:
Surface area can be calculated by adding the areas of each face on a prism:
The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468please let me know if the answer or explanation is incorrect, hope this helps :)
A mug is 1/8 full. The mug contains 1/6 of a cup of water. Find the capacity of the mug. Write the answer as a fration or mixed number
Answer:
The capacity of the mug = [tex]1\frac{1}{3}[/tex] cups
Step-by-step explanation:
Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.
To find - Find the capacity of the mug. Write the answer as a fraction or mixed number
Proof -
Let the capacity of water = x
Given that,
A mug is [tex]\frac{1}{8}[/tex] full of water
⇒Total cups of water in the mug = [tex]\frac{1}{8} x[/tex]
Now,
Given that, The mug contains [tex]\frac{1}{6}[/tex] of a cup of water.
∴ we get
[tex]\frac{1}{8} x[/tex] = [tex]\frac{1}{6}[/tex]
⇒x = [tex]\frac{1}{6}[/tex] × 8
= [tex]\frac{8}{6}[/tex]
= [tex]\frac{4}{3}[/tex] = [tex]1\frac{1}{3}[/tex]
⇒x = [tex]1\frac{1}{3}[/tex]
∴ we get
The capacity of the mug = [tex]1\frac{1}{3}[/tex] cups
