Answer:
x= -2/9
Step-by-step explanation:
step 1: isolate the variable
27x+4 = 9x
-9x. -9x
18x+4 = 0
-4. -4
18x = -4
step 2: isolate the variable by dividing both sides by the coefficient
18x = -4
÷18. ÷18
=
x = -2/9

1. The area of Alabama is 51,718 square miles and its population is 4,779,736. The area of Missoun is 69,709 square miles and its population is 5,988,927. The average state population density is 87,4 people per square mile. How do the population densities of Alabama and Missouri compare to the national average?
Answer:
Alabama is greater than the national average Missouri is less than national average
Step-by-step explanation:
Find the pop densityof each state = people / mi^2
Alabama 4779736 / 51718 = 92.4 people per square mile
Missouri 5988927 / 69709 = 85.9 people per square mile

The value of the mean of team C and team D will be equal. Then the correct option is B.
What is Mean?The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency. Arithmetic mean is a term used to describe the average. It's the percentage of the actual number of observations to the sum of the observations.

Then the mean of team D will be
[tex]\mu _d = \dfrac{120 +121 +122 +123 +124 +.....+139 +140}{21}\\\\\mu _d = \dfrac{2730}{21}\\\\\mu _d = 130[/tex]
Then the value of the mean of team C and team D will be equal.

Suppose a random sample of biweekly snowfalls in the pacific northwest has a sample mean of x¯=22.2 inches, with a sample standard deviation of s=3.5 inches. Since snowfall amounts in this area are generally symmetric and bell-shaped, we can apply the Empirical Rule.
Between what two amounts are approximate 99.7% of the data?
Using the Empirical Rule, it is found that 99.7% of the data will be between 11.7 and 32.7 inches.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In this problem, considering the mean and the standard deviation of the data-set, the bounds between which 99.7% of the data-set are given by:
22.2 - 3 x 3.5 = 11.7 inches.22.2 + 3 x 3.5 = 32.7 inches.More can be learned about the Empirical Rule at https://brainly.com/question/24537145
#SPJ1
Answer: 11.7 & 32.7
Step-by-step explanation:
Approximately $99.7\%$ of the snowfall amounts are between 1$$ inches and 2$$ inches.
Correct answers:
1: 11.7 2: 32.7
The Empirical Rule states that approximately 99.7% of the data is within 3 standard deviations of the mean. In terms of the sample mean x¯ and sample standard deviation s, that is between x¯−3s and x¯+3s.
The value 3 standard deviations below the mean is
x¯−3s=22.2−3(3.5)=11.7.
The value 3 standard deviations above the mean is
x¯+3s=22.2+3(3.5)=32.7.
So by the Empirical Rule, we can say that approximately 99.7% of the snowfall amounts are between 11.7 and 32.7 inches.

Find the x- and y-intercept(s) of the line y = -5x + 8.
Answer:
x-intercept: (8/5, 0)
y-intercept: (0, 8)
Step-by-step explanation:
y = mx + b has y-intercept at b.
y = -5x + 8 has y-intercept at 8. The point is (0, 8).
The x-intercept occurs when y = 0.
-5x + 8 = 0
-5x = -8
x = 8/5
The x-intercept is 8/5, so the point is (8/5, 0).
what is the y intercept of F(x) = 1000(2)[tex]x^{2}[/tex]

Elijah’s home is 1.1km from the library
His journey from his home to the library, including a 2 minute stop on the way, is shown on the
graph below.
How much faster was Elijah travelling before his stop than afterwards?
Give your answer in km/h.
Elijah was travelling before his stop than afterwards with speed of 0.5 km/h.
What is formula to calculate speed or velocity?To solve for distance use the formula for distance d = vt, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour.
Before his stop, the velocity =[tex]\frac{0.4km}{0.1 h}[/tex]
= 4 km/h
After his stop, the velocity =[tex]\frac{2.7km}{2.2 h}[/tex]
= 3.5 km/h
So, 4-3.5 km/h= 0.5 km/h

where the x and y values are derived from the given points
here the given points are (11,3) and (6,9)
assigning variables
(x1,y1) = (11,3) so x1 = 11 and y1 = 3
(x2,y2) = (6,9) so x2 = 6 and y2 = 9
plugging in values into formula
recall formula [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

30% of Elm trees have a certain disease. If you sample 80 elm trees, what is the probability that less than 20 trees have the disease?
The probability that less than 20 trees have the disease is; 0.135
How to find the Probability?
The formula for binomial probability is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾
We are told that 30% of Elm trees have a certain disease. Thus;
p = 30% = 0.3
n = 80
x = 20
Thus, probability that less than 20 trees have the disease is;
P(X < 20) = P(X = 0) + P(X = 1) + P(X = 2) + ....... + P(X = 19)
Using a binomial probability calculator online gives us;
P(X < 20) = 0.135

When 12 is multiplied by a fraction less than one, which of the following is true about the product.
(I don't know what are the answer choices, but I'm sure this should be one of the choices:)
Answer:
The product of 12 multiplied with a fraction less than 1 will be less than 12 itself.
Step-by-step explanation:
This is true because if you multiply 12 by (for example) 1/2, then your answer is going to be 6 since 12x1=12 itself, and 12x0=0. So that's why, if it's less than 1, then the product is going to be less than 12 itself.
