In 5.......4........3.......2......1...... ANSWER
Answer:
It's C
Step-by-step explanation:
The mean number of days employee were sick is 4.43 days.
Option C is correct.
Here,
Given that;
The department manager recorded the number of sick days taken last year by each employee, as shown in the table.
We have to find the mean number of days employee were sick.
What is Mean?
The average of the given numbers is called Mean and is calculated by dividing the sum of given numbers by the total number of numbers.
Now,
In given table;
Number of sick days are,
7, 4, 2, 6, 4, 5, 3
Hence,
Mean number of days employee were sick = [tex]\frac{7+4+2+6+4+5+3}{7}[/tex] [tex]= \frac{31}{7}[/tex][tex]= 4.4285[/tex]
Now, Rounding the number to the nearest hundredth we get;
Mean of number of days employee were sick = 4.43 days
Hence, The mean number of days employee were sick is 4.43 days.
Option C is correct.

you pay 9.70 for 2.5 pounds of roasted peanuts. You buy 1.4 pounds of almonds for 8.55 per pound.
How much less do roasted peanuts cost per pound than almonds?
How much more do you spend on almonds than on roasted peanuts.
$9.70 / 2.5lbs = $3.88 / pound of roasted peanuts.
$8.55 * 1.4lbs = $11.97 / 1.4 pounds of almonds
$8.55 - $3.88 = $4.67.
Roasted peanuts cost $4.67 less per pound than almonds.
$11.97 - $9.70 = $2.27
You spend $2.27 more on almonds than you do roasted peanuts.

What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form. A.y= 3/5x+4/5 B.y= 3/5x-4/5 C.y=-3/5x-4/5
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.

Step-by-step explanation:
sara says. "if you subtract 14 from my number and multiply the difference by -4, the result is -80." What is Sara's number?
Answer:
34
Step-by-step explanation:
We can solve this equation by giving Sara's number a variable.
Let it be x.
Then we solve by simply interpreting the problem step by step.
"If you subtract 14 from my number..."
x - 14
"...and multiply the different by -4..."
-4(x-14)
"...the result is -80"
-4(x-14) = -80
Now that we have our equation, we can solve for x.
1.) Use distributive property to expand.
-4x + 56 = -80
2.) Subtract 56 from both sides
-4x = -136
3.) Divide by -4
x = 34
Sara's number is 34
Using distributive property to expand, it is found that Sara's number is; 34
What is distributive property?The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
We need to solve this equation by giving Sara's number a variable.
Let the Sara's number a variable be x.
Then we solve by simply interpreting "If you subtract 14 from my number..." means
x - 14
Then "...and multiply the different by -4..." means -4(x-14)
"...the result is -80"
-4(x-14) = -80
Now that we have our equation,
1.) Use distributive property to expand;
-4x + 56 = -80
Subtract 56 from both sides;
-4x = -136
Now Divide by -4
x = 34
Hence, Sara's number is; 34

Given the function y= 2x if x>0 x−3 if x≤0 . Find its values for x=1; 3; 0; −2. Answer: If x = 1, then y = . If x = 3, then y = . If x = 0, then y = . If x = −2, then y = .
Answer:
Step-by-step explanation:
Given the function y= 2x if x>0 and x−3 if x≤0, to find the value of the function for x = 1, we will substitute x = 1 into the function y = 2x since x>0 at that point.
If x = 1;
y = 2(1)
y = 2
Hence when x = 1, y = 2
If x = 3, we will still use the function y = 2x since 3 is still grater than 0 satisfying the condition x>0.
y = 2(3)
y = 6
Hence when x = 3, y = 6
when x = 0, since x is zero, we will substitute x = 0 into the function x-3 because x≤0 at this point.
If y = x-3
y = 0-3
y = -3
Hence when x = 0, y = -3
when x = -2, we will substitute x = 0 into the function x-3 because -2 is also less than zero
If y = x-3 for x≤0
y = -2-3
y = -5
Hence when x = -2, y = -5

Answer:
6
Step-by-step explanation:
point D = -6
point A = 18
distance between point D and A: 18 - (-6) = 24
midpoint distance = 24/2 = 12 units away from each point
-6 + 12 = 6
18 - 12 = 6
your midpoint is at 6
Answer:
6
Step-by-step explanation:
-6 to 18 is a difference of 24. half of 24 is 12.-6 + 12 is 6 so 6 is halfway between point d and point a

Question 2
64 is 40% of what number?
А
128
B
256
160
D
26
Answer:
answer is 160
Step-by-step explanation:
1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.
5. Now we have two simple equations:
1) 100%=40
2) x%=64
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 64 is what percent of 40
100%/x%=40/64
(100/x)*x=(40/64)*x
100=0.625*x
100/0.625=x
160=x
x=160
now we have:
64 is 40% 160
