Answer:
D!
Step-by-step explanation:
To find the area, we multiply the length times the width to find the number of squares in each box.
A) 1 square down times 7 squares across is 1 x 7, which is 7.
B) 2 squares down times 6 squares across is 2 x 6= 12.
C) 3 squares down times 5 squares across is 3 x 5 = 15.
D) 4 squares down times 4 squares across = 4 x 4 =16.
16 is the biggest number here, so that is the greatest area!

The least-squares regression line yˆ=1.8−0.2x summarizes the relationship between velocity, in feet per second, and depth, in feet, in measurements taken for a certain river, where x represents velocity and y represents the depth of the river. What is the predicted value of y, in feet, when x=5?
Answer:
0.8
Step-by-step explanation:
It is 0.8 because since you have y=1.8-0.2x (which is in the form of y=mx+b); and you have the value that x=5, all that you have to do is plug in 5 into the X in the equation.
Here is shown work:
y=1.8-0.2x
y=1.8-0.2(5)
y=1.8-1
y=0.8
Hopefully this helps! :)
The predicted depth value when the velocity value is 5 will be 0.8 feets
Given the regression model :
yˆ=1.8−0.2x
yˆ = Predicted value
x = velocity
To calculate the predicted depth, at a given velocity, x ;
Substitute the value of x and solve for yˆ in the equation
When x = 5
yˆ=1.8−0.2(5)
yˆ=1.8− 1.0
yˆ = 0.8
Therefore, the predicted depth value in feet is 0.8

Answer: The first number is 9, the second number is 17, and the third number is 68.
Step-by-step explanation:
Using the given information we will represent the first number by f , the second number by s, and the third number by t.
The first number is 8 less than the second and we will represent that by the equation, f= s-8
The third number is 4 times the second and it will be represented by the expression, t= 4s
We know the sum of the numbers has to equal 94 so we will add them.
The first number is s-8, the second is s, and the third is 4s.
(s - 8) + (s) + 4(s) = 94 Solve for s to find the second number.
6s - 8 = 94
+8 +8
6s = 102
s = 17
The second number is 17 and we will input 17 in for s to solve for the first and third numbers.
f= 17 - 8
f= 9
The first number is 11.
t= 4(17)
t = 68
The third number is 68.
Check: Now add them to see if they equal to 94.
9+ 17 + 68 = 94
94 = 94

the complement of an angle is 40° more than four times itself.find the supplement angle
Answer:
Supplement angle: 170°
Step-by-step explanation:
Equations
Let x=the required angle. Since complementary angles sum 90°, then 90-x is the complement of x. According to the conditions of the question:
[tex]90-x=40+4x[/tex]
Simplifying:
[tex]90-40=4x+x=5x[/tex]
Solving:
[tex]x=50/5=10[/tex]
The angle is 10°. The supplement angle is 180°-10°=170°.
Supplement angle: 170°

16=48x-6y
swap the sides of the equation
48x-6y=16
Divide both sides of the equation by 2
24x-3y=8
now we do the same only different way ok
48x-6y=16
Divide both sides of the equation by 2
(48x-6y)÷2=16÷2
Distribute 2 through the parentheses
48x÷2-6y÷2=16÷2
calculate the quotient
48x÷2-6y÷2=8
calculate the quotient
24x-6y÷2=8

The ratio of the number of men to the number of women in a sports club is 5:2.
After 63 men and 12 women quit the club, the ratio of the number of men to the number of women became 7:4.
How many members did the club have in the beginning?
Let the number of men and the number of women in the beginning be x and y
Now,[tex]\sf \frac{x} {y} =\frac{5}{2} \\\\\sf
=2x=5y \\\\\sf
=x=\frac{5y}{2}[/tex]
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes[tex] \frac{x-63}{y-12}=\frac{7}{4} \\\\\sf
=4(x-63)=7(y-12) \\\\\sf
=4x-252=7y-84 \\\\\sf
Putting,\:x=\frac{5y}{2}\:in\: 4x-252=7y-84\:we\: get, \\\\\sf
10y-252=7y-84 \\\\\sf
=10y-7y=252-84 \\\\\sf
=3y=168 \\\\\sf
=y=56 \\\\\sf
=\boxed{Y=56}
[/tex]
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,
[tex]\sf 2x=5\:x\:56 \\\\\sf
x=\frac{5\:x\:56}{2} \\\\\sf
x=\frac{5\:x\: \cancel{56}\:\:28}{ \cancel{2}} \\\\\sf
=x=5\: x\: 28 \\\\\sf
x=140 \\\\\sf
\boxed{x=140}

Hence, the number of men was 140 and the no. of women was 56

Answer:
C. Identity Property
Step-by-step explanation:
edge2020
Have a great day y'all :)
The equation [ a + bi + 0 + 0i = a + bi ] is identity property. Then option C is correct.
What is identity property?For addition, 0 serves as the identification element. The initial number is obtained by adding any number to 0. Example ( a+0=a). 1 serves as the identity element in multiplication. The result of multiplying any number by 1 is the original number.
The expression is,
a+ bi + 0+0i = a+bi
In the above number a+bi, another zero complex number 0 + 0i is added the result is the same as before. Hence, it is identity property.

In baseball, two statistics, the ERA (Earned Run Average) and the WHIP (Walks and Hits per Inning Pitched), are used to measure the quality of pitchers. For both measures, smaller values indicate higher quality. The following computer output gives the results from predicting ERA by using WHIP in a least-squares regression for the 2017 baseball season.
Answer:A
Step-by-step explanation:
