Answer:
The predicted score for the dependent variable will be of 198,454.4.
Step-by-step explanation:
Equation of a regression line:
The equation of a regression line has the following format:
[tex]y = ax + b[/tex]
In which a is the slope and b is the intercept. x is the independent variable while y is the dependent variable.
A certain regression line equation has the slope equal to 326.07 and an intercept that is equal to 8.19.
So [tex]y = 326.07x + 8.19[/tex]
What will be the predicted score for the dependent variable if the independent variable is 608.6?
y when x = 608.6. So
[tex]y = 326.07*608.6 + 8.19 = 198454.4[/tex]
The predicted score for the dependent variable will be of 198,454.4.

The diagram shows a playground in the shape of a trapezium.
50 m
U
32m
90 m
Work out the area of the playground.
Answer:
[tex] 2240 {m}^{2} [/tex]Step-by-step explanation:
Given,
Parallel sides of the trapezium = 50m, 90m
Height of the trapezium = 32m
Therefore,
Area of the trapezium
[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \: \times \: height[/tex]
[tex] = \frac{1}{2} \times (50 + 90)m \times 32m[/tex]
= (50 + 90) m × 16m
= 140m × 16m
[tex] = 2240 {m}^{2} (ans)[/tex]
Answer:
A = 2240 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 32 , b₁ = 90 and b₂ = 50 , then
A = [tex]\frac{1}{2}[/tex] × 32 × (90 + 50) = 16 × 140 = 2240 m²
describe and correct the error in solving the equations below
9514 1404 393
Answer:
19. wrong multiplier was used, and used incorrectly; x = -324
20. wrong multiplier was used, and used incorrectly; y = 5
Step-by-step explanation:
In each case, the equation was multiplied by the coefficient of the variable, instead of divided. In each case, the square of the coefficient was evaluated incorrectly (so the error wasn't noticed).
__
19) As described above.
(-36)(9) = (x/9)(9)
-324 = x

Caroline puts $400 into a savings account that earns 6% annually. Write a function that represents this situation, where t is the time in years. Solve algebraically after how many years she will get $1200 in her account (round it to the nearest year).
Answer: 19 years
Step-by-step explanation:
Given
Amount invested [tex]\$400[/tex]
Rate of interest [tex]R=6\%[/tex]
after 1-year amount becomes
[tex]A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424[/tex]
After n years it is
[tex]A=400\left (1.06\right)^n[/tex]
Sum accumulated is [tex]\$1200[/tex]
[tex]\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}[/tex]

Hope it helps :)
Have a great day!
The net below represents a container. What solid figure does it show?
____________________Solution :-We can see that the given net has 12 edges, 6 faces and 8 vertices if we compile it up. These number of edges, faces and vertices are found in a cuboid or a rectangular prism. With this we can conclude that if we compile the given net, it will form a cuboid or a rectangular prism. So, the given net is of a cuboid or a rectangular prism.
____________________Final Answer :-The given net is of a cuboid or a rectangular prism.
____________________f(x)= square root of x-5. find f-1 (x) and it’s domain
Answer:
Option B.
Step-by-step explanation:
Inverse function:
Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.
The domain of the inverse function(x values) is the range of the original function(y values).
Original function:
[tex]f(x) = \sqrt{x} - 5[/tex]
Domain is [tex][0,\infty)[/tex], and when [tex]x = 0, f(x) = -5[/tex]. So the range is [tex][-5,\infty][/tex], that is, [tex]y \geq -5[/tex]
Inverse function:
[tex]y = \sqrt{x} - 5[/tex]
Exchanging x and y
[tex]x = \sqrt{y} - 5[/tex]
[tex]\sqrt{y} = x + 5[/tex]
[tex](\sqrt{y})^2 = (x+5)^2[/tex]
[tex]y = (x+5)^2[/tex]
The inverse function is [tex]f^{-1}(x) = (x+5)^2[/tex]
Domain:
Range of the original function is [tex]y \geq -5[/tex], so the domain of the inverse function is [tex]x \geq -5[/tex]. The correct answer is given by option B.
Answer:

the spinner shown below has 12 congruent sections. the spinner spun 150 times. what is a reasonable prediction for the number of items the spinner will land on an even number. (pls help asap!!)
Answer:45
Step-by-step explanation:
There are 3 even numbers out of A total of 8 numbers.
Each spin would have a 3/8 chance of landing in an even number.
Multiply the chance of landing on even by number of spins:
120 x 3/8 = 360/8 = 45
The answer would be 45 times.

consider the series 1/4+1/16+1/64+1/256
The expression that defines Sn is option (A), Sn = lim n->∞ (1/4)^n is the correct answer.
What is a series?A sequence is defined as an arrangement of numbers in a particular order. A series is the cumulative sum of a given sequence of terms. Typically, these terms are real or complex numbers.
For the given situation,
The series is 1/4 + 1/16 + 1/64 + 1/256.
⇒ [tex]\frac{1}{4}+\frac{1}{16} +\frac{1}{64} +\frac{1}{256}[/tex]
⇒ [tex]\frac{1}{4}+\frac{1}{4^{2} } +\frac{1}{4^{3} } +\frac{1}{4^{4} }[/tex]
Thus the sum of this series can be obtained by the expression,
[tex]S_{n}= \lim_{n \to \infty} (\frac{1}{4^{n}})[/tex]
⇒ [tex]S_{n}= \lim_{n \to \infty} (\frac{1}{4})^{n}[/tex]
Hence we can conclude that the expression that defines Sn is option (A), Sn = lim n->∞ (1/4)^n is the correct answer.

How many solutions does the equation 5x+17=4(3x−1) have?
Answer:
one solution = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+17=4(3x−1)
Step 1: Simplify both sides of the equation.
5x+17=4(3x−1)
5x+17=(4)(3x)+(4)(−1)(Distribute)
5x+17=12x+−4
5x+17=12x−4
Step 2: Subtract 12x from both sides.
5x+17−12x=12x−4−12x
−7x+17=−4
Step 3: Subtract 17 from both sides.
−7x+17−17=−4−17
−7x=−21
Step 4: Divide both sides by -7
-7x/-7 = -21/-7 = 3

If you have $4.00, how many pounds of apples can you buy?
A. 7 pounds
B. 7/4 of a pound
C. 4/7 of a pound
D. 2 2/7 pounds
Answer:
[tex]2 \frac{2}{7}[/tex] pounds, D
Step-by-step explanation:
1 pound of apples = 1.75 dollars.
Set the number of pounds of apples as x.
Then, we can write this equation.
1.75x = 4
[tex]\frac{7}{4}[/tex]x = 4
Divide both sides by [tex]\frac{7}{4}[/tex]
x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]
x = [tex]\frac{16}{7}[/tex]
x = [tex]2 \frac{2}{7}[/tex]
Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds
