Mr. Greg had $300 to
purchase equipment
for summer camp. He
bought 6 basketballs
and 6 soccer balls.
Each basketball cost
$16.98, and each
soccer ball cost
$13.79.
Answer:
c
Step-by-step explanation:
6 x 16.98 = 101.88
+ 6 x 13.79 = 184.62
300 - 184.62 = 115.38
Answer:
$115.38
Step-by-step explanation:
6×$16.98=$101.88=cost of basketballs
6×$13.79=$82.74=cost of soccer balls
cost of basketballs + cost of soccer balls = total cost
$101.88+$82.74=$184.62
money to purchase - total cost = leftover money
$300.00 - $184.62 = $115.38

The perimeter of a rectangle is 48 feet, and the length is 16 feet. what is the area?
Answer: [tex]128ft^2[/tex]
Step-by-step explanation:
If the 16ft is the sum for both sides already means the first length is 8ft and also the second length is 8ft. then since there are 32 ft more left, you divide it by two since there were two widths left, the values of the two widths are 16ft each. so the sum of the two widths is 32ft. and that's the final answer.
[tex]Length=16[/tex]
[tex]Perimeter=48[/tex]
[tex]Using ~the ~formulas:[/tex]
[tex]A=wl[/tex]
[tex]P=2(l+w)[/tex]

The axis of symmetry for the graph of the function f(x)=3x2 bx 4 is x equals three-halves. what is the value of b? −18 −9 9 18
Using the vertex of the quadratic equation, it is found that the value of b is of -9.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
The axis of symmetry is [tex]x = x_v = -\frac{b}{2a}[/tex].
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, we have that the function is defined as follows:
[tex]f(x) = 3x^2 + bx + 4[/tex]
We have that [tex]a = 3, x_v = \frac{3}{2}[/tex], hence the value of b is found as follows:
[tex]x = -\frac{b}{2a}[/tex]
[tex]\frac{3}{2} = -\frac{b}{6}[/tex]
b = -6 x 3/2
b = -9.

In a recent poll, 18% of seniors said they will attend the upcoming prom. Twenty seniors chosen at random were asked if they plan to attend the prom. What is the probability that at most 5 seniors will attend the prom?
Question 3 options:
0.136
0.149
0.758
0.864
Using the binomial distribution, it is found that there is a 0.864 = 86.4% probability that at most 5 seniors will attend the prom.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, we have that:
18% of seniors said they will attend the upcoming prom, hence p = 0.18.Twenty seniors chosen at random were asked if they plan to attend the prom, hence n = 20.The probability that at most 5 seniors will attend the prom is given by:
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.18)^{0}.(0.82)^{20} = 0.0189[/tex]
[tex]P(X = 1) = C_{20,1}.(0.18)^{1}.(0.82)^{19} = 0.0829[/tex]
[tex]P(X = 2) = C_{20,2}.(0.18)^{2}.(0.82)^{18} = 0.1730[/tex]
[tex]P(X = 3) = C_{20,3}.(0.18)^{3}.(0.82)^{17} = 0.2278[/tex]
[tex]P(X = 4) = C_{20,4}.(0.18)^{4}.(0.82)^{16} = 0.2125[/tex]
[tex]P(X = 5) = C_{20,5}.(0.18)^{5}.(0.82)^{15} = 0.1493[/tex]
[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0189 + 0.0829 + 0.1730 + 0.2278 + 0.2125 + 0.1493 = 0.864[/tex]

Consider the rectangle.
The x and y axes have a range from negative 7 to 7 in increments of 1. A rectangle is on the coordinate plane.
Which points could be the vertices of the image of the rectangle after it is dilated from the origin by a scale factor of 3? Select all that apply.
Answer:
Step-by-step explanation:
Dilating with a scale factor of 3 centered at the origin means we multiply all the coordinates by 3.
(0,2) maps onto (0,6).(0,4) maps onto (0,12).(3,2) maps onto (9,6).(3,4) maps onto (9,12).Therefore, the answers are the second option and the sixth option.
