Given a mean of 80 and a standard deviation of 3, label the normal curve below.
Answer:
The points from the left;
71, 74 , 77, 80, 83, 86 , 89
Step-by-step explanation:
Here, we want to label the normal curve given the mean and the standard deviation
From what we have, the central part is the mean while the other parts are deviations from the mean
We will label the graph starting from the left to the right
1 is 3 SD from the mean (negatively)
That will be 80-3(3) = 80-9 = 71
2 is 2 SD away
That will be;
80 -2(3) = 80-6 = 74
The 3rd part is 1 SD away
That will be 80-3 = 77
The midpoint is for the mean which is 80
The point after this will be;
80 + 3 = 83
The point after this will be;
83 + 3 = 86
Next is
86 + 3 = 89
What is the measure of angle x? (1 point)
1) 25 degrees
2) 40 degrees
3) 55 degrees
4) 105 degrees
Answer:
x=55degree because x+25=80 so x=55
Answer:
55°
Step-by-step explanation:
This is because that angle is 80° but is split into two and 80-25=55

In ∆ABC, ∠A is a right angle, and ∠B measures less than 40°. Which of the following phrases best describes the measure of ∠C?
The phrase that describes the measure of ∠C is greater than 50°.
What is a right triangle?A right triangle is a triangle that has one of its angle as 90 degrees.
The triangle is named as ABC.
∆ABC
where
∠A = 90 degrees
∠B < 40 degrees
The sum angles in a triangle is 180 degrees.
Therefore,
let x be the third angle
Hence,
∠A + ∠B + ∠C = 180°
∠B + ∠C = 180 - 90
∠B + ∠C = 90°
∠B < 40 degrees
Therefore,
∠C > 50 degrees.

b x=15
c x=5
d x=1
Answer:
D. x=1
Step-by-step explanation:
Image can be rewritten as 3x + 6 = 9.
Solve for x.
3x +6 = 9
Isolate x by subtracting 6 from both sides.
3x = 3
Get rid of the 3 by dividing by 3 on both sides.
x = 1

C. There is not enough information to say.
Answer:
The shown triangles have the same angles 96° and 61°, and the same length 6.
Thus, the two triangles are congruent.
Step-by-step explanation:
We know that two triangles would be termed as congruent If:
Their corresponding sides have equal lengthTheir corresponding angles have equal measureThe orientation of a congruent triangle can be different.
Consider the two triangles shown.
Though their orientation is different, both triangles have the same angles 96° and 61°, and the same length 6.

Kenise will begin college as a freshman next fall and has received a 10-year $5,500 Federal Direct Unsubsidized Loan with an interest rate of 6.8%. She will be required to begin making payments six months after graduation. How much interest will accrue while she is still in school and over the six-month grace period?
Answer:
The interest accumulated will be $3,927
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
From the question, we have P as the amount borrowed = $5,500
R is the interest rate = 6.8%
T is the time which is 10 years + 6 months = 10 1/2 years
The interest accrued will thus be;
(5,500 * 6.8 * 10.5)/100 = $3,927
Angela has $2,200 to invest at a simple interest rate of 4.5%. If she wants to earn $297 in interest, how long does she have to invest her money?
Answer:
I will not give you an answer, but I will give you how too get the equation started.
Step-by-step explanation:
set up an equation using:
x= amount invested at 3%
7800 - x = amount invested at 12%
.03(x) + .12(7800 - x) = 504
.03x +936 - .12x = 504
-.09x = -432
x = 4800

handle makes an angle of 40° with the ground?
O 11.49 foot-pounds
O 38.30 foot-pounds
O 574.53 foot-pounds
O 750.00 foot-pounds
Answer:
C) 574.53 foot-pounds
Step-by-step explanation:
got it right on edge :)
Awagon is being pulled by a force of 15 pounds. the required work done is 574.53 to pull the wagon So, Option C) is correct work done = 574.53.
What is work done?The work done is product of force and cosine of displacement.
Given; Awagon is being pulled by a force of 15 pounds. We need to find How much work is done in moving the wagon 50 feet if the handle makes an angle of 40° with the ground.
Force = 15 pounds
distance = 50 feet
Ф = 40°
We can calculate the work done as;
work done = force x displacement x cosФ
work done = 15 x 50 x cos40
work done = 15 x 50 x 0.76
work done = 574.53
Therefore, the required work done is 574.53 to pull the wagon.

Answer:
x=19/27
Step-by-step explanation:
[tex]3(5x+2)=-5(3x-5)+3x\\15x+6=-15x+25+3x\\15x+6=-12x+25\\27x=19\\x= 19/27[/tex]
Hope this helps plz hit the crown :D
[tex]3(5x+2)=-5(3x-5)+3x[/tex]
Distribute 3 in 5x+2 and -5 in 3x-5
[tex]15x+6=-15x+25+3x[/tex]
Multiplying 2 negatives will be positive (Same goes to dividing 2 negatives.)
[tex]15x+15x-3x=25-6[/tex]
Move the x term to the same side and constant term to the same side.
(Whenever you move to another side, change the sign/operator to opposite. From plus to minus and from multiply to divide.)
[tex]27x=19\\x=\frac{19}{27}[/tex]
Thus, the answer is 19/27
