What are the 'x' and 'y' intercepts of the equation 2y + 17 = 6x - 19?
Answer:
x=6,0
y=0,-18
Step-by-step explanation:
Answer:
x-intercept: (6,0)
y-intercept: (0,-18)
Step-by-step explanation:
To find the x-intercept, set y=0 and solve for x.
2y=+17=6x-19
0+17=6x-19
6x=36
x=6
(6,0)
To find the y-intercept, set x=0 and solve for y.
2+17=6x-19
2y+17=0-19
2y=-36
y=-18
(0,-18)
Answer the following questions and round your answers to 2 decimal places. 31% of all college students major in STEM (Science, Technology, Engineering, and Math). If 36 students are randomly selected, find the probability that
Answer:
[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]
Step-by-step explanation:
The objective of this question is to find the probability that:
Exactly 11 of them major in STEM
So, Let assume X to be the random variable that follows a binomial distribution:
Then [tex]X \simeq Bin ( 36, 0.31)[/tex]
The probability that exactly 11 of them major in STEM can be computed as:
[tex]P(X =11 ) = ^{36} C_{11} (0.31)^{11} (1-0.31) ^{36-11}[/tex]
[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]
[tex]P(X =11 ) = \dfrac{36!}{11!(36-11)!} \times (0.31)^{11} \times (0.69) ^{25}[/tex]
[tex]P(X =11 ) =600805296 \times (0.31)^{11} \times (0.69) ^{25}[/tex]
[tex]\mathbf{P(X =11 ) \simeq 0.1429}[/tex]
Thus; the probability that exactly 11 of them major in STEM is 0.1429

the original price of a backpack is $20. The sale price is 30% off the original price. What is the sale price of the backpack?
Answer: $14
Step-by-step explanation: You have to multiply 20 by .3 (30%) which is 6. Now you subtract 6 from 20 and get 14.

How do I solve this can someone please help me as soon as possible thank you so much
can anyone help me with this?
Help! Best answer = Braniest
Answer:
x=20
Step-by-step explanation:
Since supplementary angles =180 degrees, we need to write the equation as follows:
5x-30+x+90=180
Then you need to add like terms:
6x+60=180
Then you need to subtract 60 from both sides (60 and 180)
6x=120
Then divide both sides by 6 to get
x=20

Nolan was given a box of assorted chocolates for his birthday. Each night, Nolan treated himself to some chocolates. There were originally 30 chocolates in the box and after 8 nights, there were 6 chocolates remaining in the box. Write an equation for , in terms of t, representing the number of chocolates remaining in the box C days after Nolan's birthday .
Answer: C=-3t+30
Step-by-step explanation:
The equation of remaining chocolate C in terms of t could be C =30 - 3t.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that the Initial number of chocolates in box = 30
Also after 8 nights, number of remaining chocolates = 6
Then we have
In 8 nights, 24 chocolates were treated.
In 1 night, 3 chocolates were treated.
The equation of remaining chocolate C in terms of t can be written by;
C =30 - 3t.

The base of a triangle is shrinking at a rate of 9cm/s and the height of the triangle is increasing at a rate of 7cm/s. Find the rate at which the area of the triangle changes when the height is 13cm and the base is 4cm.
Answer:
A = (1/2)*b*h
objective: find dA/dt
given: b = 26, db/dt = 2, b = (1/2)*h
since we are given db/dt lets get area in terms of b
since b = (1/2)h that means h = 2b
so A = (1/2)*b*(2b) = b^2
Take derivative wrt time, t
dA/dt = 2b*db/dt

332/10 as an mixed number
Answer:
27 2/3
Step-by-step explanation:
Hope this helps :)
Answer: 33 & 1/5
Step-by-step explanation:
Step 1 - Find Whole Number
Calculate out how many times the denominator goes into the numerator. To do that, divide 332 by 10 and keep only what is to the left of the decimal point:
332 / 10 = 33.2000 = 33
Step 2 - Find New Numerator
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
332 - (10 x 33) = 2
Step 3 - Put Together
Keep the original denominator and use the answers from Step 1 and Step 2
Step 4 - Minimize
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 332/10 as a Mixed Number.

A production line packages 3,000 boxes of cereal per hour. Quality control technicians randomly sample ten per hour and weigh them. The boxes are classified as underweight or not. X, the number of underweight boxes will be approximately ___________distributed.
Answer:
The boxes are classified as underweight or not. X, the number of underweight boxes will be approximately ___normally___distributed
Step-by-step explanation:
For a normal distribution the sample size must be less than or equal to 30.
The central limit theorem states that if a variable X from a population has a mean u and a finite variance σ² then the sampling distribution of the sample mean x bar approaches a normal distribution with mean u and variance σ²/n as the sample size n approaches infinity.
In the given question the sample size n= 10 and population size N= 3000.
Here n < 30 . But if the population is normal this theorem holds true for sample size n < 30.
The number of underweight boxes should be normally distributed.
What is a normal distribution?
It is the distribution where the sample size should be lower than or equal to 30
Since the size of the sample is n = 10 and the size of the population is N = 3000
So here n should be less than 30
Therefore, it is normally distribution.
