Solve for the value of x and y
5y 2x 40
Answer:
x=25 =18
Step-by-step explanation:
Right angle =90°
you are given 40, therefore 2x has to equal up to 50.
2x=50 divide both sides by 2
x=25
straight line=180°
you are given 90, therefore 5y has to equal to 90.
5y=90
divide both sides by 5
y=18
A function is shown below.
g(x)=19.60+1.74x
What is the value of g(30)?
Answer:
g(30) = 71.8
Step-by-step explanation:
g(30) = 19.6 + 1.74(30)
The value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
g(x)=19.60+1.74x
Plug x = 30
g(30) = 19.60+1.74(30)
g(30) = 19.60 + 52.2
g(30) = 71.8
Thus, the value of the g(30) is 71.8 if the function is g(x) = 19.60 + 1.74x

With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. The ABC Electronics Company has just manufactured 2100 write-rewrite CDs, and 60 are defective. If 3 of these CDs are randomly selected for testing, what is the probability that the entire batch will be accepted
Answer:
0.9167 = 91.67% probability that the entire batch will be accepted
Step-by-step explanation:
The CDs are chosen without replacement, which means that the hypergeometric distribution is used.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
2100 write-rewrite CDs, and 60 are defective.
This means, respectively, that [tex]N = 2100, k = 60[/tex]
3 of these CDs are randomly selected for testing
This means that [tex]n = 3[/tex]
What is the probability that the entire batch will be accepted?
Probability of none defective, so P(X = 0).
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 0) = h(0,2100,3,60) = \frac{C_{60,0}*C_{2040,3}}{C_{2100,3}} = 0.9167[/tex]
0.9167 = 91.67% probability that the entire batch will be accepted
If you roll a 6 sided die 12 times what is the best prediction possible for the number of times you will roll a four Hint: Use proportional reasoning
Answer:
the probability would be a 1/3 or a 1/6 chance i think
Marco can finish a jigsaw puzzle in 3 hours. Working together with Cliff, it takes them 1 hour. How
long would it have taken Cliff working alone?
Macro can finish the puzzle in 3 hours. We can say that her speed for working is 1/3 or 1/3 puzzle per hour.
Now if they work together, this turns into 1 puzzle per hour.
That must mean that Cliff would be doing the other 2/3 of the puzzle while Macro does his 1/3 in that hour. If Cliff has a speed of doing them 2/3 per hour. Then it would take 1 and a half hour to finish 1 whole puzzle.

Solve the right triangle
Round your answer to the nearest tenth
Answer:
B = 40°
a = 23.0
b = 19.3
Step-by-step explanation:
✔️B = 180° - (90° + 50°) => sum of triangle
B = 40°
✔️Reference angle = 50°
Opp = a
Hypotenuse = 30
Adjacent = b
Find a by applying the trigonometric function, SOH:
Sin 50 = Opp/Hyp
Sin 50 = a/30
30 × Sin 50 = a
23.0 = a
a = 23.0 (nearest tenth)
To find b, apply CAH:
Cos 50 = Adj/Hyp
Cos 50 = b/30
30 × Cos 50 = b
b = 19.3 (nearest tenth)
which is not a common multiple of 4 and 9

the two the numbers -2.6 and -2.1 are shown on the number line what is the distance between the two points
Answer:
0.5Step-by-step explanation:
The distance between the points will be the difference between the points as shown;
Difference = -2.1 - (-2.6)
Difference = -2.1 + 2.6
Difference = 2.6 - 2.1
Difference = 0.5
Hence the difference between the numbers -2.6 and -2.1 on the number line is 0.5

Jay has 6,200 beads. He is making bracelets with 9 beads each. How many bracelets can he make? How many beads will be left?
Answer: He can make 688 beads, and 8 beads will be left.
Step-by-step explanation:
First, you need to divide 6,200 by 9.
6,200 ÷ 9 = 688 R8.
688 will be the number of bracelets he can make, and the remainder, 8, will be the leftover beads because he doesn't have enough to make another bracelet.
For the labels, it says, "How many bracelets can he make?" and," How many beads will be left?"
The answers will be: 688 bracelets;8beads
Equation : 6,200÷9=x 6,200÷9=688 R8 x=688 bracelets;8 beads

Step-by-step explanation:
hello there!
Remember all of the angles in a triangle will add up to equal 180 so to find the missing angle we subtract the given angles from 180
180 - 90 - 45 = 45 so the missing angle would equal 45
