In the triangle below X=[?] cm. Round to the nearest tenth.
Answer:
x = 8.6 cm
Step-by-step explanation:
To find x, we need to take the sin ratio of the 35° angle.
Identity
sin∠x = opposing side length / length of hypotenuseSolving
sin35° = 0.57sin35° = x/15⇒ x/15 = 0.57⇒ x = 15 × 0.57⇒ x = 8.55 cm⇒ x = 8.6 cmAnswer quickly please I really need this answer right now
A bag contains:
• 5 red marbles
• 6 blue marbles
• 3 green marbles
• 2 yellow marbles
• 4 purple marbles
A student draws a random marble from the bag, records its color, and returns
it to the bag. The student makes a total of 60 draws. What is a reasonable
prediction for the number of times a green marble will be drawn?
O A. 18
O B. 10
Ос. 9
O D. 12
Answer:
Answer Choice A (8, eight)
Step-by-step explanation:
To begin, add all of the marbles together. When finished, the answer should be 20. Because the variable 20 equals 100, you divide 4 by 100. You will get 0.04 as a result. This multiplied by 20 equals 8. Finally, the answer is A.
Question
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.

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.

What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given the standard deck has 26 black cards while the total number of cards is 52. Therefore, the probability of two cards being black without replacement is,
Probability = (Probability of the first card is black) × (Probability of the second card being black)
Probability = (26/52) × (25/51)
Probability = 0.245 = 24.5%
Hence, the probability of two cards being black without replacement is 24.5%.

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]

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]
0.864 = 86.4% probability that at most 5 seniors will attend the prom.

Answer:

Step-by-step explanation:
That is not what an incenter is
The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
The G is the intersection of the bisector lines. So, the G represents the center of the incircle.
The incircle will touch all three sides of the triangle. And the distance between the center of the circle to the sides of the triangle will be known as the radius and tangent to the circle.
Then we can write a condition for a circle. Then we have
GD = GE = GF = Radius
The length GD, GE, and GF are the radius of the circle. Then GD = GE = GF is true. Thus, option A is correct.
