Answers
Answer:
8
Step-by-step explanation:
(5 + 16) / 7 + 3^2 - (1 + 3)
21 / 7 + 3^2 - 4
21 / 7 + 9 - 4
3 + 9 - 4
12 - 4
8
Use PEMDAS.
P - Parenthesis
E - Exponents
M/D - Multiply/Divide
A/S - Add/subtract
So for this:
Start with parenthesis: (5+16) and (1+3), so 21 and 4
Then exponent: 3^2, which is 3*3 which is 9
Then divide: 21/7 is 3
And then the rest: 3 + 9 - 4. 3+9 is 12, 12-4 is 8, so you're answer is 8.

Adam writes a number. The number is
greater than 50 and less than 54.
What numbers could Adam have
written? Explain.
Answers
Answer:
51, 52, 53
Step-by-step explanation:
51, 52, and 53 are all greater than 50, but less than 54
The possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.
What is the number system?Number systems are mathematical systems that are used to express numbers in various ways.
Given that the number is "greater than 50 and less than 54", which means it must be strictly between those two values.
Here, the range of numbers that Adam could have written is (50, 54), which means any number greater than 50 and less than 54, but not including 50 and 54 themselves.
Thus, the possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

Required
Number of households without computer in 2009
From the attachment, we have:
[tex]n=5170000[/tex] --- survey
[tex]p = 22.3\%[/tex] --- proportion without computer
So, the actual number is:
[tex]Number = p * n[/tex]
[tex]Number = 22.3\% * 5170000[/tex]
[tex]Number = 1152910[/tex]
[tex]Number \approx 1153000[/tex]

find the median and mean 42,15,14,48,39
Answers
Answer:
Hello! the answer is 39 and 32
Step-by-step explanation:
To find the median we need to reorder the numbers from lowest to highest:
14,15,39,42,48
The one in the middle is the median! If there happens to be an even number, take the two middle numbers add them, together and divide them by 2.
To find the mean (also know as the avergae) we need to add all the numbers together and divide by the number of values that are present:
42+15+14+48+39 = 158
158/ 5 = 31.6 or 32
Hope this helps!

Jenny runs a daycare center and charges $60 per day for each child. There are currently 50 children enrolled at the daycare. At a recent conference, Jenny was advised to lower her rates in order to stay competitive in her area. For each price decrease of $4 per day, the number of children enrolled at the center increases by two.
Write the equation that can be used to determine the number of price decreases, x, in dollars, for which the daycare center has a daily revenue of $2,800.
A.
(60 - 4x)(50 + 2x) = 2,800

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 132 t + 108 h ( t ) = - 16 t 2 + 132 t + 108 models the ball's height above the ground, h ( t ) h ( t ) , in feet, t t seconds after it was thrown. a) What is the maximum height of the ball?
Answers
Answer:
The maximum height of the ball is 380.25 feet in the air.
Step-by-step explanation:
The quadratic function:
[tex]h(t)=-16t^2+132t+108[/tex]
Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.
We want to determine the maximum height of the ball.
Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.
Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:
[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]
So, the maximum height occurs after 4.125 seconds of the ball being thrown.
To find the maximum height, substitute this value back into the equation. Thus:
[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]
The maximum height of the ball is 380.25 feet in the air.

"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?
Answers
Answer:
10x
Step-by-step explanation:
Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF
First let us find the factors of each terms
60x³ = 6 * (10 * x) * x²
10x² = 1 * (10 * x) * x
30x = 3 * (10 * x)
From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

So the first one doesnt work since it repeats to every single digit that exists.
The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.
Answer:
B
Step-by-step explanation:
Hello There!
In order for the relations to be a function the x values may not repeat
For answer choice A the x value -2 repeats multiply times therefore the relation is not a function
For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices
For answer choice C the x values -3 and 2 repeat therefore it is not a function
For answer choice D the x value 2 repeats therefore the relation is not a function
So we can conclude that the correct answer is B
