y=-4x+9
Step-by-step explanation:
We will find an equation in the form of y = mx + b. We know m must be -4(because the slope must be the same for parallel lines), so we need to solve for b, which is the y-intercept. To do that, we will plug in the point C, giving us [tex]5 = -4 * 1 + b[/tex]. Adding 4 to both sides gives us b = 9, so that is the y-intercept.
Victoria deposited $15,000 into a savings account that earns an annual simple interest rate of 0.2% to the nearest 10th of a year how long will it take for the account to reach 15,500
Answers

Answer:
Step-by-step explanation:
sus
It will take about 16.7 years to reach $15500.
What is the interest rate?The percentage that a lender adds to the amount of money lent to them is called an interest rate.
Given that, the initial deposited amount is P = $15000, the interest rate is r= 0.2% annually, and the final amount is $15500.
The interest earned is calculated by subtracting the initial amount from the final amount:
15500-15000
=500
Therefore, the interest earned is $500.
Now, the formula for the simple interest is:
interest = P × r × t
Substitute the known values:
500 = 15000 × 0.2% × t
500 = 15000 × 0.2/100 ×t
500 = 30t
t = 500/30
t = 16.7
Hence, It will take about 16.7 years to reach $15500.

Answers
The probability is it that someone will correctly guess an 8-digit entry code is 0.022.
Given that,
A keypad with 10 buttons marked 0 through 9 is located at the building's entrance.
We have to find how much probability is it that someone will correctly guess an 8-digit entry code.
We know that,
Probability is defined as the ratio of the number of required outcomes to the total number of outcomes.
Based on the details provided;
One outcome is expected if the needed number of outcomes is 8-digits.
Since there are 10 numbers and 8 numbers need to be chosen, the total number of outcomes is ¹⁰C₈.
Considering that the lock can only be opened by 8 digits;
The probability that someone will properly guess a 8-digit input code is
P=1/¹⁰C₈
P=1/10!/8!2!
P=1/10×9/2
P=1/45
P=0.022
Therefore, The probability is it that someone will correctly guess an 8-digit entry code is 0.022.

Given
p(x) = 4x³+cx²+x+2
p(-2) = 4(-2)³+c(-2)²+(-2)+2
p(-2) = 4(-8) + c(4)-2+2
p(-2) = -32+4c

t = [tex]\frac{210-225}{\sqrt{\frac{20^2}{16}+\frac{23^2}{21}}}[/tex]

Answers
The last digit of a₃₅ is 8 when each phrase (beginning with the third term) in the sequence $$1,2,2,4,8,32,256 is the product of the two terms that came before it.
Given that,
Each phrase (beginning with the third term) in the sequence $$1,2,2,4,8,32,256 is the product of the two terms that came before it. For instance, the seventh term, which is the sum of the fifth ($8) and sixth ($32) terms, is $256. Though the numbers very rapidly become large, this series can go on indefinitely! In terms of the number of particles in the observable universe, the $14 term, for instance, is close to some estimations.
We have to find what is the final digit of the sequence's $35 term.
We know that,
Remember the Fibonacci sequence, which goes 1, 1, 2, 3, 5, 8, 13, 21..., where each word is the total of the one before it. Continuing the above pattern, if Fn is the n-th Fibonacci number, we would arrive at

Three things determine the margin of error:
Confidence level: The margin of error grows in proportion to the level of confidence.

Answers
The probability that fewer than 21 customers in the sample buy coffee during their visit on that certain day of the week is 0.7224. Hence option C is the correct option.
What is the binomial distribution?
When each trial has the same probability of achieving a given value, the number of trials or observations is summarised using the binomial distribution. The likelihood of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.
The formula for z-score is z = (x -μ)/σ
Where, μ is mean of the sample, σ is standard deviation of the sample
Given that 55% of the customers buy coffee, hence p = 55% = 0.55
Sample of 35 customers, hence n = 35.
For the binomial distribution μ = np, σ = √[np(1-p)]
The mean and the standard deviation of the approximation are:
μ = 35 ˣ 0.55 = 19.25
σ = √[35 ˣ 0.55(1-0.55)] =2.943
Now calculate the z score where μ = 19.25, σ = 2.943 and X = 21
z = (21 -19.25)/2.943
z = 0.59
The value of p is 0.2776 when z score is 0.59.
The probability is 1 - 0.2776 = 0.7224.

When we do a confidence interval for the mean, we use T-distribution to determine the number of standard deviations needed for our confidence
The T-distribution is a way to describe a collection of observations in which the majority of the observations are close to the mean and the remaining observations are the tails on either side. It is a type of normal distribution that is utilized for data with unknown variance and smaller sample sizes.
We use the T-distribution to obtain the required critical value, which is nothing more than the number of standard deviations from the center taken to obtain the confidence interval, despite the fact that there is no population standard deviation and only sample metrics—the sample mean and standard deviation—are used.

The p-value provides the minimal level of significance at which the null hypothesis would be rejected as an alternative to rejection points. The alternative hypothesis is more likely to be supported by greater evidence when the p-value is lower.
P-value is frequently utilised by government organisations to increase the credibility of their research or reports.

Answers
The slope of a function is defined as the change in y-coordinate with respect to the change in x-coordinate of the line.
m = Δy/Δx
∆y --> net change in the y coordinate
∆x ---> net change in x coordinate
m ---> slope of fution
The y-intercept of both functions 'f' and 'g' are equal and slope of f(x) is less than the slope of g(x). So, the correct option is option (A).
We have given a function, g (x) = 2x + 1
comparing the g(x) with standard equation
y = mx + b
where m is slope of this line
b --> y-intercept
Thus we get m = 2 , b= 1 . So, the slope of g(x) is 2 and y-intersecpt is 1 .
Now, we have a table for function f(x) that is function f(x) passing through all points as given in table. The slope of function passing through (h,k) and (a,b) is expressed as (k-b)/(h-a)
Thus, slope of function 'f' passing through (0,1) and (2,4) = (1-4)/(0-2) = -3/-2
= 3/2
=> f (x) = (3/2)x + b
where , b --> y-intercept
plug the value x= 4 and corresponding to it
f(x) = 7 we get , 7 = 3/2× 4 + b
=> b = 7-6 = 1
Therefore, slope of function g(x) is greater than slope of function f(x) and y-intercept of f(x) is equal to y-intercept g(x) .

B. The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
C. The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
D. The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
If the nth term of a number sequence is n^2 + 2n,
find the first 3 terms and the 10th term.
Answers
Answer:
3, 8, 15 and 120
Step-by-step explanation:
to find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule
n = 1 : 1² + 2(1) = 1 + 2 = 3
n = 2 : 2² + 2(2) = 4 + 4 = 8
n = 3 : 3² + 2(3) = 9 + 6 = 15
the first 3 terms are 3, 8, 15
to find the 10th term , substitute n = 10 into the rule
n = 10 : 10² + 2(10) = 100 + 20 = 120
