Ronnie's teacher wrote this expression on the board. (-4)(2) + (10/2) What is the value of this expression?
Answer:
The answer would be -3.
Step-by-step explanation:
If you follow PEMDAS, the first set of parenthesis, (-4)(2), would equal -8. The next set of parenthesis, (10/2), would equal 5. Adding -8 and 5 together gives you -3.

According to the US Census, the percent of residents aged 65 or older in the 50
states and District of Columbia has mean 13.26% and standard deviation of
1.67%. Find and interpret the standardized scoreſfor the state of Colorado, which
had 9.7% of residents age 65 or older. *
Answer:
z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean.
Step-by-step explanation:
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado means the score is below the mean
In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
A pet store is having a pet fish sale. Mrs. Smith bought koi and paid with a $50 bill. Write an algebraic expression to represent how much change Mrs. Smith got back.
The expression that represents the change Mrs. Smith got back is 50 - x dollars.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A pet store is having a pet fish sale.
let, the cost of the Koi fish is 'x' dollars.
Therefore, With a $50 bill change(C) Mrs. Smith got back is represented by the expression,
C = (50 - x) dollars.

The sum of Paul’s and Sam’s ages is 4 and the difference between their ages is 0. Two equations to model this situation are x + y = 4 and x - y = 0. The solution represents both of their ages. What quadrant does the solution lie in?
A.) IV
B.) II
C.) III
D.) I
Answer:
D.) |.
Step-by-step explanation:
x + y = 4
x - y = 0 Adding:
2x + y - y = 4
2x = 4
x = 2
and y = 4 - 2 = 2.

If a persons monthly income consists of $550 plus a commision of 4% on all his sales. Find his total income for a month where he sold items for $590
Answer:
$613.6
Step-by-step explanation:
Given data
Monthly income = $550
Plus commision =4% of sales
Sale for the month= $590
Let us find the commission earned
4/100*590
=0.04*590
=$23.6
Hence the net income for that month is
=23.6 +590
= $613.6

I need help im doing IXL right now (BB.3 Complete a function table: quadratic functions)

Answer:
0, 2, 4
Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4
The function table is solved and the quadratic equation is f ( x ) = -3x²
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
f ( x ) = -3x²
when x = -2
f ( -2 ) = -3 ( -2 )²
f ( -2 ) = -12
And , when x = 0
f ( 0 ) = 0
when x = 2
f ( 2 ) = -12
when x = 4
f ( 4 ) = -48
Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

Select the correct answer. Two events, E1 and E2, are defined for a random experiment. Which equation represents the condition that the events are nonexclusive? A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
Answer:
B
Step-by-step explanation:
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.
We have given that,
A. P(E1 ∩ E2) ≠ 0 B. P(E1 ∪ E2) ≠ 1 C. P(E1 ∩ E2) = 0 D. P(E1 ∪ E2) = 1
We have to determine which equation represents the condition that the events are nonexclusive.
What is nonexclusive?
Non-mutually exclusive events are events that can happen at the same time.
The equation that represents the condition that the events are nonexclusive is P(E1 ∪ E2) ≠ 1.
