what is the value of x in the figure Pls help
Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18

Pretty much, it's just 46 times 7. So, you can do 322 jumping jacks in 7 minutes.
Please mark me as Brainliest, I need it to move onto the next level. =D
Analysing the Question:
We are given the function:
f(x) = 46x
where x is the number of minutes and f(x) is the number of jumping jacks in the given number of minutes
Number of jumping jacks in 7 minutes:
replacing x with number of minutes (i.e, 7). We get:
f(7) = 46*7
f(7) = 322 jumping jacks

If product of two numbers=384HCF=8,2cm=?
Answer:
96 and 288
Step-by-step explanation:
So, we need to find 2 numbers such that their sum is 8 and they do not have common factor (Relatively prime). Both these numbers will be divisible by 48 but there would be no other common divisor (after dividing by 48).
Such order independent pairs are (1,7) and (3,5).
Difference between them would be (7–1)*48=6*48 and (5–3)*48=2*48 respectively.
The differences are 6*48=288 and 2*48=96.
We have found difference without finding numbers.
Ans.: 96 and 288
p.s.: The number pairs (again order neutral) would be (48, 336) and (144, 240)
Difference for 48 and 336 add up to 384, their HCF is 48. These two numbers match the conditions. Their difference is 288.
Difference of 144 and 240 add up to 384, their HFC is 48 (the numbers are 48*3 and 48*5, common factor is 48 and no other common factor for 3 and 5; 48 is HCF). The difference is 96.

What are the features of the quadratic function ƒ(x) = (x – 3)(x + 7)?
Question 8 options:
A)
Vertex = (2,25), y-intercept = (0,21), x-intercepts = (7,0) and (–3,0), axis of symmetry is x = 2
B)
Vertex = (–2,–25), y-intercept = (0,–21), x-intercepts = (–7,0) and (3,0), axis of symmetry is x = 2
C)
Vertex = (–2,–25), y-intercept = (0,–21), x-intercepts = (–7,0) and (3,0), axis of symmetry is x = –2
D)
Vertex = (–2,25), y-intercept = (0,21), x-intercepts = (7,0) and (3,0), axis of symmetry is x = –2
Answer:
Option C:Vertex = (–2,–25), y-intercept = (0,–21), x-intercepts = (–7,0) and (3,0), axis of symmetry is x = –2
Step-by-step explanation:
We are given the function;
f(x) = (x - 3)(x + 7)
The axis of symmetry in a quadratic equation is given by the formula;
x = -b/2a
Expanding the function given, we have;
f(x) = x² + 4x - 21
a = 1
b = 4
c = - 21
Thus;
Axis of symmetry is:
x = -(4)/(2 × 1)
x = -2
Now, y-intercept is when x = 0
Thus;
f(0) = (0 - 3)(0 + 7)
f(0) = - 3 × 7 = - 21
y - intercept is (0, - 21)
x-intercept is when f(x) = 0
Thus;
(x - 3)(x + 7) = 0
Thus;
x - 3 = 0 or x + 7 = 0
x = 3 or x = - 7
x - intercept is (-7, 0) and (3,0)
The y-coordinate of vertex will be at the line of axis of symmetry.
Thus, we will put x = -2 into the function to get;
y = (-2 - 3)(-2 + 7)
y = -5 × 5 = - 25
Vertex is at (-2, -25)
Correct Answer is option C
Answer:
Vertex = (–2,–25), y-intercept = (0,–21), x-intercepts = (–7,0) and (3,0), axis of symmetry is x = –2

In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of eight candidates for three local teaching positions consisted of five who had enrolled in paid internships and three who enrolled in traditional student teaching programs. All eight candidates appear to be equally qualified, so three are randomly selected to fill the open positions. Let Y be the number of internship trained candidates who are hired.
a. Does Y have a binomial or hypergeometric distribution? Why?
b. Find the probability that two or more internship trained candidated are hired.
c. Find the standard deviation and mean of Y.
Answer:
A) Hypergeometric
B) P( X ≥ 2) = 0.7143
C) Standard deviation: σ = 0.7087
Mean = 1.875
Step-by-step explanation:
A) Y has Hypergeometric distribution. This is because, the population is not definite and is largely a finite number of people that have one of the two characteristics. Also, a sample of 8 was selected from this population and a random variable of interest that contained the number of people with one of the characteristics.
B) We are told total candidates were 8.
Thus; N = 8
3 were for local teaching positions, thus; n = 3
5 were for paid internship, thus; r = 5
Now, the formula for Hypergeometric distribution is;
P(y) = {(rCy) × [(N-r)C(n-y)]}/(NCn)
Where C represents combination.
Thus, probability that two or more candidates were hired is;
P( X ≥ 2) = P(2) + P(3)
Now, N - r = 8 - 5 = 3
For P(2); n - y = 3 - 2 = 1
For P(3); n - y = 3 - 3 = 0
Thus;
P(2) = {(5C2) × (3C1}/(8C3)
P(2) = 30/56
P(2) = 0.5357
P(3) = {(5C3) × (3C0}/(8C3)
P(3) = 10/56
P(3) = 0.1786
Thus;
P( X ≥ 2) = 0.5357 + 0.1786
P( X ≥ 2) = 0.7143
C) Formula for standard deviation in Hypergeometric distribution is;
σ = √[(nr/N) × ((N - r)/n) × ((N - n)/(N - 1))]
nr/N = (3 × 5/8) = 15/8
((N - r)/N) = (8 - 5)/8 = 3/8
((N - n)/(N - 1)) = (8 - 3)/(8 - 1) = 5/7
σ = √((15/8) × (3/8) × (5/7))
σ =√0.5022
σ = 0.7087
Formula for mean in Hypergeometric distribution is;
E(Y) = nr/N = 3 × 5/8 = 1.875
