Which expression entered into a graphing calculator will return the probability
that a data value in a normal distribution is between a z-score of -0.18 and a
Z-score of 1.99?
A. normalcdf(0.18, 1.99)
B. normalcdf(-1.99,0.18)
C. normalcdf(1.99, 0.18)
O
D. normalcdf(-0.18, 1.99)
The expression that returns the probability that a data value in a normal distribution is between a z- score of -0.18 and a z-score of 1.99 is (d) normalcdf(-0.18, 1.99)
How to determine the expression?To calculate the probability between two z-scores is to calculate the area between the z-scores.
This is done using the following syntax:
normalcdf(lower bound, upper bound)
From the question, the lower and the upper z-scores are -0.18 and 1.99
So, the formula would be normalcdf(-0.18, 1.99)
Hence, the expression is (d)

Answer:
24
Step-by-step explanation:
Given the solution
2 < x ≤ 24
The ≤ symbol means less than or equal to
Thus x can equal 24
At the other end 2 < x which means x cannot equal 2
Thus x = 24 will make the inequality true
24 because the equation says greater than or equal to 24, but greater than 2.
Which of the following are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle?
Answer:
B. and D.
Step-by-step explanation:
We have that an equilateral triangle is a regular polygon, that is to say, it has its three equal sides.In traditional Euclidean geometry, the equilateral triangles are also equiangular, that is, the three interior angles are equal and measure 60 °. By symmetry of the equilateral triangle, we have to:
Any two equilateral triangles are similarly congruent, therefore:
B. Two segments that are both congruent to a third segment must be congruent to each other

Three departments of factory employ a total of 1274 people. Department B employs 70 people more than department A and department C employs 84 more workers than department B. How many people work in each department?
Answer:
No . of people in department A = 350
No . of people in department B = 420
No . of people in department C = 504
Step-by-step explanation:
Let the no . of people in department A be x
Given
Department B employs 70 people more than department A
Therefore,
no . of people in department B = x + 70
Again Given
department C employs 84 more workers than department B.
Therefore,
no . of people in department c = no . of people in department B + 84
no . of people in department c = x + 70 + 84 = x + 154
Total no. of people in all the department in terms of x = x + x+ 70+ x+154
Total no. of people in all the department in terms of x = 3x +224
Problem says
Three departments of factory employ a total of 1274 people
Therefore
3x +224 = 1274
=> 3x = 1274 - 224 = 1050
=> x = 1050/3 = 350
Thus,
no . of people in department A = x = 350
no . of people in department B = x + 70 = 350 + 70 = 420
no . of people in department c = x + 154 = 350 + 154 = 504
Answer:
People in department A: 350
People in department B: 420
People in department C: 504

Solve the equation.
x2 - x - 12 = 0
Answer:
x = 4 or x = -3
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - x - 12 = 0
The left hand side factors into a product with two terms:
(x - 4) (x + 3) = 0
Split into two equations:
x - 4 = 0 or x + 3 = 0
Add 4 to both sides:
x = 4 or x + 3 = 0
Subtract 3 from both sides:
Answer: x = 4 or x = -3

the ratio of boys to girls in a school is 4:5 there are 22o boys in the school. How many students attend the school
Answer:
495 students
Step-by-step explanation:
The 4 part of the ratio is the number of boys.
Divide the number of boys by 4 to find the value of one part of the ratio.
220 ÷ 4 = 55 ← value of 1 part of the ratio, thus
5 parts = 5 × 55 = 275 ← number of girls
Number of students = 220 + 275 = 495
Answer:
495 studentsStep-by-step explanation:
[tex]220 \: boys \\ 4:5 = 4 + 5 \\ boys \: = \frac{4}{9} \times x = 220 \\ = \frac{4x}{9} = \frac{220}{1} [/tex]

{(−2,8),(2,1),(−4,8),(7,9)}
Answer:
A - Not Function
B - Function
C - Function
D - Not Function
E - Function
Step-by-step explanation:
For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function
(Consult the diagram below)
A - {(6,12),(3,1),(−1,13),(6,4)}As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.
B - {(−1,−2),(−4,−4),(0,−5),(7,−5)}No repetition of x, IT IS A FUNCTION.
C - {(−5,1),(4,10),(5,10),(6,7)}No repetition of x, IT IS A FUNCTION.
D - {(−1,4),(1,6),(−1,−2),(0,7)}As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.
E - {(−2,8),(2,1),(−4,8),(7,9)}No repetition of x, IT IS A FUNCTION.
George Washington was born on 2-22-1732. He died in 1799 at the age of 67. The month in which he died and the day of the month on which he died are consecutive even integers whose product is 168. When did Washington die? month day year
Answer:
George Washington died on December 14th, 1799
Numerical with the arrangement: month - day - year
12 - 14 - 1799
Step-by-step explanation:
In the question, we are told that: the month in which he died and the day of the month on which he died are consecutive even integers whose product is 168.
Therefore,
If one positive even integer = Month he died is represented by x
The second consecutive even integer = Day he died = x + 2
Their product =
x ( x + 2) = 168
x² + 2x = 168
x² + 2x - 168 = 0
We factorise
x² + 14x - 12x - 168 = 0
(x² + 14x) - (12x - 168) = 0
x(x + 14) - 12(x + 14) = 0
(x - 12)(x + 14) = 0
x - 12 = 0, x = 12
x + 14 = 0 , x = -14
Our answer cannot be a negative interger, hence x = 12
So the first positive even integer = 12
The second positive even integer = x+2 = 12 + 2 = 14
Therefore, the month he died = n = 12th month = December
The day he died = n + 2 = 14 = 14th day.
Hence, George Washington died on December 14th, 1799
Numerical with the arrangement: month - day - year
12 - 14 - 1799
