Marco is turning the expression (x-4)^2 into a trinomial. He writes down what is shown below. What is his error?
Answers
=x^2-4x-4x+16
=x^2-8x+16
it’s +16, not negative. he forgot that when you add two negatives together, it becomes positive.
Answer:
Step-by-step explanation:
first, let's solve the equation ourselves.
(x-4)^2= (x-4)(x-4)= x^2−8x+16
now, we can see what's different about the two.
we can say that Marco's answer had the number 16 as a negative, when it was supposed to be positive. Marco wrote the incorrect sign.
g The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC). A local hospital randomly selects five births and lets the random variable X count the number not resulting in a defect. Assume the births are independent. What is the probability that at least one of the births results in a defect
Answers
Answer:
0.1426 = 14.26% probability that at least one of the births results in a defect.
Step-by-step explanation:
For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability that a birth results in a defect is independent of any other birth. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [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]
And p is the probability of X happening.
The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).
This means that [tex]p = \frac{1}{33}[/tex]
A local hospital randomly selects five births.
This means that [tex]n = 5[/tex]
What is the probability that at least one of the births results in a defect?
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(\frac{1}{33})^{0}.(\frac{32}{33})^{5} = 0.8574[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8574 = 0.1426[/tex]
0.1426 = 14.26% probability that at least one of the births results in a defect.

Discount 75%, Sale Price $74.75, Original Price-?
Answers
Answer:
You will pay $18.69 for a item
Step-by-step explanation:
if you buy an item at $74.75 with 75% discount, you will pay 74.75 - 56.0625 = 18.69 dollars.
Answer:
$299
Step-by-step explanation:
The discount is 75%, so the sale price represents 25% of the original price.
25% : $74.75
(multiply both sides by 4 to get 100%)
100% : $299

A culture of bacteria has an initial population of 470 bacteria and doubles every 8 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 7 hours, to the nearest whole number?
Answers
Answer:
Step-by-step explanation:
The population of bacteria in the culture after 7 hours is approximately 883.
What is an exponential function?Several real-world phenomena, including population expansion, radioactive decay, compound interest, and the spread of diseases, are modeled using exponential functions. In calculus, where they are used to define the exponential and logarithmic functions—essential ideas in calculus and other fields of mathematics—they also play a significant role.
Using the formula [tex]P_t = P_0 \times 2^{\frac{t}{d}}[/tex], where P_t is the population after t hours, P₀ is the initial population, t is the time in hours and d is the doubling time, we can find the population of bacteria in the culture after 7 hours as follows:
Since the initial population is 470, we have P₀ = 470.
The doubling time is 8 hours, so we have d = 8.
Substituting these values into the formula, we get:
[tex]P_7 = 470 \times 2^{\frac{7}{8}}[/tex]
P₇≈ 882.77

Median: 69
First Quartile: 65.5
Third Quartile: 73
Interquartile Range: 7.5
Step-by-step explanation:
First, put all of the numbers in order.
63, 64, 67, 68, 70, 72, 74, 76.
Median
For the median, it is the center of the data set.
To find the median of this data set, add 68, and 70, then divide by 2.
The Median is 69.
First Quartile
To find the first quartile, find the range below the median (63-68).
Find the median of that range.
Add 64 & 67 together, then divide by 2.
The first quartile = 65.5
Third Quartile
Do the same as the first quartile, but do it with the range above the median (70-76).
Add 72 & 74 together, then divide by 2.
The third quartile = 73.
Interquartile Range
Now, take the first and third quartile, and subtract.
[tex]73-65.5=IR[/tex]
[tex]7.5 = IR[/tex]
The interquartile range is 7.5.

Answer:
D. 7
Step-by-step explanation:
According to this problem, the sum of the angles is 90°. This means we're adding.
2x + 3x + 8 + 7x - 2 = 90.
To make this easier to solve, we can combine like terms.
2x + 3x + 7x = 12x.
The remaining numbers are 8 and -2.
8 + -2 = 6
Our final expression is:
12x + 6 = 90
First, subtract 90 from 6 and get 84.
Lastly, divide the difference (84) by 12.
12x = 84
84 / 12 = 7.
Therefore, the value of x is 7.
