Answer:
y = 34
Step-by-step explanation:
PEMDAS =
Parenthesis

Division
Addition
Subtraction
Remember to follow PEMDAS. First, multiply -6 with 4:
-6 * 4 = -24
-24 + y = 10
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Add 24 to both sides:
-24 (+24) + y = 10 (+24)
y = 10 + 24
y = 34
y = 34 is your answer.

The area of a rectangle is 46 square inches. If the length is 4 times the width, then find the dimensions of the rectangle. Round off your answers to the nearest hundreth.
Answer:
So the breadth of the rectangle is y= 3.39 inches
And the length is = x= 4y= 4* 3.39= 13.56 inches
Step-by-step explanation:
Let the length of the rectangle be given by x and the breadth be defined by y.
Then according to the area of rectangle
Area= Length * breadth
But length is 4 times its width so x= 4y
Therefore putting the values
Area= Length * breadth
46= x*y
46= 4y*y
46/4= y²
or
y ²= 11.5
Now taking the square root of both sides we get
y= √11.5=3.39116 inches
So the breadth of the rectangle is y= 3.39 inches
And the length is = x= 4y= 4* 3.39= 13.56 inches

The coefficient of determination is used to: compute correlations for truncated ranges. compare the relative strength of coefficients. identify curvilinear relationships. test correlations for causality.
Answer: compare the relative strength of coefficients.
Step-by-step explanation: The Coefficient of determination usually denoted as R^2 is obtained by taking the squared value of the correlation Coefficient (R). It's value ranges from 0 to 1 and the value obtained gives the proportion of variation in the dependent variable which could be attributed to it's correlation or relationship to th independent variable. With a R^2 value close to 1, this means a large portion of Variation in a variable A could be explained due to changes in variable B while a low value signifies a low variance between the variables. Hence, the Coefficient of determination is used in comparing the relative strength of the Coefficients in other to establish whether a weak or strong relationship exist.
How do you estimate an irrational vsquare root? Use COMPLETE sentences! Make sure you use LOTS of details. Word Bank Square Root Square Estimate Predict - Perfect Squares Whole Number Number Line Left/Right Tick Marks Upper/Lower Radical Consecutive
Answer:
Step-by-step explanation:
Lets illustrate one method by an example:
Find the square root of 12:
The 2 perfect squares around 12 are 3^2 and 4^2 so the square root of 12 is going to be between 3 and 4.
We might predict it to be 3.5
If we square 3.5 we get 12.25 so we are pretty close.
It is less than 3.5 so we might try 3.4 .
Working 3.4^2 out we get 11.56 so we know the square root is between 3.4 and 3.5 Since 12.25 is closer to 12 than 11.56, the square root is closer to 3.5 than 3.4 so we might try 3.46.
This is called the method of trial and improvement and requires you to do long multiplications.

Step-by-step explanation:
The fraction is 23/5.
To find the fraction of given problem.
What is fraction?A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
Given that:
Let the two fractions be a/b and c/d then:
a/b−c/d=ad−bc/bd
It must have like denominators to subtract fractions.
For = 9 1/10 - 4 3/4= 9 1/10 - 19/4
Taking LCM of 10 and 4 is 20.

the utility industry has 428.5 thousand jobs in 2010 and is expected to decline at an average rate of 3 thousand jobs per year from 2010 to 2020 assuming this holds true what will be the utilities percent change for 2010 to 2020
Answer: 7%
Step-by-step explanation:
Given: Initial jobs = 428.5 thousand
Average rate of declining of jobs from 2010 to 2020 = 3 thousand jobs per year
From 2010 to 2020 , there are 10 years.
Total jobs declines till 2020 = 10 x (3 thousand)
= 30 thousand (Change in jobs)
Now, utilities percent change for 2010 to 2020 : [tex]\dfrac{change \ in \ job\ numbers}{Initial\ jobs}\times 100[/tex]

Analyses were run. The following is the (edited) output for the test:
Hypothesis test results:
U1: favored team-home game
U2: favored team- away game
Difference Sample Mean Std. Err. DF T-Stat P-value
U1-U2 .11 0.67168534 94.155815 0.16376716 0.4351
From the output we learn that:
A. the data provide sufficient evidence reject the H0; thus, we cannot conclude that the
mean point spread of home games is higher than that of away games.
B. the data do not provide sufficient evidence reject the H0; thus, we can conclude that
the mean point spread for home games is higher than that of away games.
C. the data do not provide sufficient evidence to reject H0; thus, we cannot conclude that
the mean point spread of home games is higher than that of away games.
D. the data provide sufficient evidence to reject H0; thus, we can conclude that the mean
point spread for home games is higher than that of away games.
Answer: C. The data do not provide sufficient evidence to reject H0; thus, we cannot conclude that the mean point spread fo home games is higher than that of away games.
Step-by-step explanation: In Hypothesis Testing using p-value, after stating the null an alternative hypothesis, you have to compare p-value with level of significance, also known as α. If p-value is less than α, reject null hypothesis and accept alternative. If p-value is bigger, we would fail to reject null hypothesis and not accept the alternative.
In the above testing, P-value is 0.4351. Level of significance is, generally, 0.05. Comparing them, p-value is bigger than α. What it means is there is not enough evidence to support null hypothesis and, consequently, we can't conclude the difference in mean point spread of home games is higher than of the away games.

Step-by-step explanation:
golf ball: 4/3П(0.8)^3=2.14 in^3
storage unit: 120(240)(96)=2764800 in^3
2764800/2.14=1291962 golf balls
Number of golf balls that will fit inside of a storage will be 1291962 golf balls
diameter of golf ball = 1.6 in³
radius will be = 0.8 in³
it is known that 1 ft = 12 in

For the figure below m<ABC = 70°. Which theorem or postulate can be used to determine m<DBC? What is m<DBC? (pic of the drawing below)
Answer:
38°
Step-by-step explanation:
<ABD and <DBC are two interior angles that make up <ABC.
Based on the Angle Addition Theorem, the following equation can be used to find m<DBC:
[tex] (3x + 5) + (6x - 16) = 70 [/tex]
Find x
[tex] 3x + 5 + 6x - 16 = 70 [/tex]
[tex] 9x - 11 = 70 [/tex]
[tex] 9x = 70 + 11 [/tex]
[tex] 9x = 81 [/tex]
[tex]x = \frac{81}{9} [/tex]
[tex] x = 9 [/tex]
We are given that, m<DBC = (6x - 16)°
Plug in the value of x to find the measure
m<DBC = 6(9) - 16 = 54 - 16 = 38°

S = 2
Step-by-step explanation:
1st step: Simplify both sides of the equation
4/5 s - 3/4 s = 1/10
4/5 s + -3/4 s = 1/10
(4/5 s + -3/4 s) = 1/10 (combine like terms)
1/20 s = 1/10
1/20 s = 1/10
step 2: multiply both sides by 20
20 * (1/20 s) = 20 * (1/10)

In statistics, a sample randomly taken from an investigated population, usually known as a random sample. To avoid having bais from our response and for it to have the best chance of it being indicative of the entire population, our sample must be random. This random sample chosen must contain subjects related to the data in the population we what to obtain a result from.
