If Kevin wants a 90 average in math after 5 tests and his first 4 tests are 76, 92, 89 and 97 what does he need on the fifth test for a 90 average?
Answers
Solving for the average is simple:
Add up all of the exam scores and divide that number by the number of exams you took.
(87 + 88 + 92) / 3 = your average if you didn't count that fourth exam.
Since you know you have that fourth exam, just substitute it into the total value as an unknown, X:
(87 + 88 + 92 + X) / 4 = 90
Now you need to solve for X, the unknown:
87
+
88
+
92
+
X
4
(4) = 90 (4)
Multiplying for four on each side cancels out the fraction.
So now you have:
87 + 88 + 92 + X = 360
This can be simplified as:
267 + X = 360
Negating the 267 on each side will isolate the X value, and give you your final answer:
X = 93
Now that you have an answer, ask yourself, "does it make sense?"
I say that it does, because there were two tests that were below average, and one that was just slightly above average. So, it makes sense that you'd want to have a higher-ish test score on the fourth exam.
current count = 4
current sum = 76+92+89+97=354
we need average = 90 = sum/5
so, we need sum = 90*5=450
To get sum 450, he needs to score 450-354=96 on his best test.
Now, (76+92+89+97+96)/5=90

In quadrilateral PQRS, PQ = QR = RS = SP, PR = 14, and QS = 48. Find the perimeter of PQRS.
Answers
Answer:
100 units
Step-by-step explanation:
Lengths of diagonals:
PR = 14
QS = 48
Since all 4 sides are equal in length, it's a rhombus
Length of each side:
sqrt[(14/2)² + (48/2)²]
sqrt(625)
25
Perimeter = 4 × 25
= 100
The side length of the rhombus is 25 units. Then the perimeter of the rhombus PQRS will be 100 units.
What is the perimeter of the shape?The complete stretch of a shape's border is referred to as the perimeter in geometry. A shape's periphery is calculated by summing the lengths of all of its sides and borders. Its dimensions are expressed in linear units like centimeters, meters, inches, and feet.
In quadrilateral PQRS, PQ = QR = RS = SP, PR = 14, and QS = 48. The diagonal of the rhombus intersect at a right angle. Then the side length of the rhombus is given as,
a² = (14 / 2)² + (48 / 2)²
a² = 49 + 576
a² = 625
a = 25
Then the perimeter of PQRS will be given as,
P = 4a
P = 4 x 25
P = 100 units
The side length of the rhombus is 25 units. Then the perimeter of the rhombus PQRS will be 100 units.
More about the perimeter of the shape link is given below.

The probability that exactly half of the colonies will thrive = (1/3) = 0.3333
Step-by-step explanation:
The list of random numbers simulates the out comes of 4 colonies.
Based On the simulation in 6 trails, what is the probability that exactly half of the colonies will thrive?
The probability of an event is given mathematically as the number of elements in the event divided the total number of elements in the sample space.
Noting that the numbers 0 to 6 indicate that a colony thrives and the number 7 to 9 represent that a colony doesn't thrive.
The 6 trials are given as
4285; 3 colonies thrive, 1 doesn't.
6903; 3 colonies thrive, 1 doesn't.
3829; 2 colonies thrive, 2 don't.
7871; 1 colony thrives, 3 don't.
2868; 2 colonies thrive, 2 don't.
5137; 3 colonies thrive, 1 doesn't.
The number of trials where exactly 2 colonies thrive = 2
The total number of trials = 6
The probability that exactly half of the colonies will thrive = (2/6) = (1/3) = 0.3333

Answer:

Step-by-step explanation:
Write equations with j own information:
Adult + child = 200
Adult = 200 - child
3.00 Adult + 1.50 child = 510
Combine equations:
3.00(200-child) + 1.50 child = 510
Simplify:
600 -3.00 child + 1.50 child = 510
600 - 1.50 child = 510
Subtract 600 from both sides:
-1.50 child = -90
Divide both sides by -1.50
Child = -90 / -1.50
Child = 60
There were 60 child seats sold and 140 adult seats sold.

EM, EQ-secants
Prove: MP·EW=WQ·EP
Answers
Answer:
Step-by-step explanation:
A secant is a straight line from a point outside a given circle that passes through two points on its circumference.
From the given diagram, EM and EQ are secants.
Thus,
<PEW ≅ <WEP (common angles)
<EMP ≅ <EQW (secant-chord theorem)
<WMP ≅ <PQM (inscribed angles of arc WP)
Therefore,
[tex]\frac{EW}{WM}[/tex] = [tex]\frac{EP}{PQ}[/tex] (corresponding sides of a triangle)
This implies that,
EW*PQ = EP*WM
Therefore,
MP*EW = WQ*EP (properties of a similar triangle)

Answers
Answer:
D hope this help :)
Step-by-step explanation:(☞ﾟヮﾟ)☞☜(ﾟヮﾟ☜)
(12 + 6) × (11 − 7) = 72, is equal to 72 is a True statement.
The correct option is D.
To make the statement true by inserting parentheses, we need to follow the correct order of operations (also known as the PEMDAS or BODMAS rule).
According to this rule, multiplication and division should be performed before addition and subtraction.
Let's examine the options:
A. 12 + (6 × 11) − 7 = 72
B. 12 + 6 × (11 − 7) = 72
C. (12 + 6) × 11 − 7 = 72
D. (12 + 6) × (11 − 7) = 72
To determine the correct option, let's evaluate each expression:
A. 12 + (6 × 11) − 7 = 12 + 66 − 7 = 71 (not equal to 72)
B. 12 + 6 × (11 − 7) = 12 + 6 × 4 = 12 + 24 = 36 (not equal to 72)
C. (12 + 6) × 11 − 7 = 18 × 11 − 7 = 198 − 7 = 191 (not equal to 72)
D. (12 + 6) × (11 − 7) = 18 × 4 = 72
Thus, (12 + 6) × (11 − 7) = 72, is equal to 72 is a True statement.
