Answer:
0.65542
Step-by-step explanation:
The formula for calculating a z-score when a random sample is selected is is z = (x-μ)/standard error
where
x is the raw score
μ is the population mean
Standard error = σ/√n
σ is the population standard deviation.
n = randomly selected sample
z = (x-μ)/standard error
z = (3.08 - 3.10) / 0.20/ √16
= -0.02/0.2/4
= -0.02/0.05
= - 0.4
Determining the Probability value from Z-Table:
P(x≤ 3.08) = P(<3.08)
P (z = -0.4)
= 0.34458
P(x>3.08) = 1 - P(x<3.08)
1 - 0.34458
= 0.65542
Therefore, the likelihood the sample mean is greater than $3.08 is 0.65542
What is the horizontal distance between the two points (-7,-4) and (12,-4)? Remember that distance is always positive! Hint: The horizontal distance is represented by the 1st number in each coordinate. What is the difference between -7 and 12?
==================================================
Explanation:
Draw out a number line. Plot -7 and 12 on the number line. Draw in the tickmarks between them. You should find the distance from -7 to 12 is 19 units since you need to go 19 spaces from either -7 to 12, or vice versa.
You can use subtraction to get
-7-12 = -19
or
12-(-7) = 12+7 = 19
The final result is made positive since negative distance does not make sense.
So you'd have |-7-12| = |-19| = 19 or |12-(-7)| = |19| = 19.
All of this only works because the two y coordinates are the same, which makes a horizontal line through the two given points.

3.) Yvonne's hourly wage is raised from $11.09 per hour to $12.35 per hour. She works 40 hours
per week. How much more does she earn per week at the new rate?
Answer: She earns 50.4 much than she did on her other pay per hour.
Step-by-step explanation: First multiply 11.09 by 40, you get 443.6, then multiply 12.35 by 40 you get 494.0, so then you subtract the two total paychecks, and that's how you get the answer 50.4, more money.
Hope this helps. :)
Is (4,1) (8,1) (8,2) (12,2) (12,3) (16,4) (20,3) a function, yes or no?!
Answer:
No, it is not a function
Step-by-step explanation:
A function is where there is no two of the same domain.
The domain is the first coordinate.
Hope This Helps :)
Answer:
it not a function
Step-by-step explanation:
Since x = 12 produces y = 2 and y = 3, the relation
(4,1),(8,1),(8,2),(12,2),(12,3),(16,4),(20,3)
is not a function.
The relation is not a function.

Greg mixes 10 cans Black paint with 16 cans of white paint to get a gray paint. How many cans of black paint will he need to mix with 96 cans of white paint to get the same gray color?
Answer:
60 cans
Step-by-step explanation:

10 time 6 is 60
I need to change the subject to x
(x - 4y) / w = 9
Multiply both sides by w
x - 4y = 9w
Add 4y to both sides
x = 9w + 4y
2 - 6k = 5 - 3k - 12 k =
Answer:
k = 3
Step-by-step explanation:
2 - 6k = 5 - 3k -12
Add like terms at RHS
2 - 6k = -3k - 7
Add 6k to both sides
2 - 6k + 6k = -3k - 7 + 6k
2 = 3k - 7
Add 7 to both sides
2 +7 = 3k
9 = 3k
Divide both sides by 3
9/3 = 3k/3
3 = k
k = 3

Find the equation of the line through (10, 4) that is parallel to the line with the equation
y = -1x + 3. Give the equation in standard form.
Answer:
x + y = 14
Step-by-step explanation:
The question asks for the final answer to be an equation in standard form. The standard form of the equation for a line is ...
ax +by = c
where a, b, c are integers with no common factors, and 'a' is positive.
__
When working with parallel and perpendicular lines, standard form is an easy form to work with. The coefficients (a and b) of parallel lines will be the same. All that is different between parallel lines is the value of 'c'.
Given this fact, it is convenient to start by putting the given equation into standard form. For that, we want the x-term on the same side of the equal sign as the y-term.
Adding x to both sides of the given equation puts it in standard form:
x +y = x +(-x) +3
x + y = 3 . . . . . simplified
__
Now that we know our equation will be of the form ...
x + y = (some constant)
we need to find the constant. We can do that by using the given point values for x and y.
For the given point (x, y) = (10, 4), the constant for the parallel line will be ...
x + y = 10 + 4 = 14
x + y = 14 . . . equation of parallel line through (10, 4)

a survey of 800 people who binge-watch were asked how many episodes is too many to watch in one viewing session. the results are displayed in the bar graph. explain how this graph is misleading
Answer:
The graph is misleading because the vertical scale is not even. It goes from 0 to 15 and then thereafter the scale reverts to a scale of 5.
This is misleading because had the graph gone in a scale of 5 from the get go, the number of people who thought 3-4 episodes were too much would have looked higher in the graph as they seem to comprise of about 5% of the sample population.
The scale should begin at 0 and then go like 5 ⇒ 10 ⇒ 15 ⇒ 20 ⇒ 25 ⇒ 30

The summit of a mountain pass is 8,050 ft above sea level. the valley below is 12 and 1/2 ft below sea level. what is the vertical distance between the summit and the valley
please please help me
Answer:
Vertical distance between the valley and the summit = 8062.5 ft
Step-by-step explanation:
Distances above the sea level are denoted by positive notations and below the sea level by negative notation.
Summit of a mountain pass = 8050 (above the sea level)
Valley below the sea level = 12 and half ft = (-12.5) ft
Distance between the summit and the valley = 8050 - (-12.5)
= 8050 + 12.5
= 8062.5 ft
Therefore, Vertical distance = 8062.5 ft will be the answer.
