helpp plss
Answer:
Step-by-step explanation:
It would be 2.43ft cubed. You first have to multiply 6 x 9 to get 54 and then Do 54 x 4.5 to get 243 ft cubed. Next you have to put it in fraction form 243/100. After that you have to divide 243 by hundred( you can do this by moving the decimal place two places to the left) and you get the answer 2.43 ft cubed

Solve the equation using the method of completing the square.
Answer:
D) x = ± 2√5 - 4
Step-by-step explanation:
2x² + 16x - 8 = 0
Yah, i plugged this into m a t h w a y
(all of ur questions pretty much can use this app or website)
Answer:
D
Step-by-step explanation:
Given
2x² + 16x - 8 = 0 ( divide through by 2 )
x² + 8x - 4 = 0 ( add 4 to both sides )
x² + 8x = 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = 4 + 16
(x + 4)² = 20 ( take the square root of both sides )
x + 4 = ± [tex]\sqrt{20}[/tex] = ± [tex]\sqrt{4(5)}[/tex] = ± 2[tex]\sqrt{5}[/tex] ( subtract 4 from both sides )
x = - 4 ± 2[tex]\sqrt{5}[/tex] → D
A high school basketball coach wants to see whether there is a linear relationship between player height, x , and the number of points scored in a game by basketball players in the coach’s state, y. The 96 percent confidence interval to estimate the slope of the linear regression line relating player height to points scored in a game is calculated to be (−0.432,1.844) . Assume all conditions for inference for the slope of a regression line were met. Based on the confidence interval, which of the following claims is supported by the confidence interval?
A. Each player scored at most 1.844 points in a game.
B. The average difference between actual points scored and predicted points scored is between -0.432 and 1.844.
C. There is a positive linear relationship between player height and number of points scored for basketball players in the coach's state.
D. There is a negative linear relationship between player height and number of points scored for basketball players in the coach's state.
E. It cannot be determined whether the linear relationship between player height and number of points scored for basketball players in the coach's state is positive or negative
Answer:
E
Step-by-step explanation:
Since 0 is in confidence interval, and negative and positive values are also, we are 96% confident in all possible answers in this interval so since true slope could be negative or positive in our interval, we cannot determine it
It cannot be determined whether the linear relationship between player height and number of points scored for basketball players in the coach's state is positive or negative (Option E)
How to interpret the confidence interval?Suppose the confidence interval at P% for some parameter's values is given by
[tex]x \pm y[/tex]
That means, that parameter's estimated value is P% probable to lie in the interval
[tex][x-y,x+y][/tex]
For this case, the slope of the linear regression line relating player height to points scored in a game is in the interval (−0.432,1.844) with 96% confidence.
So, we are 96% sure about the slope of the considered linear regression being in this interval. There is nothing more conveyed by this confidence interval about the slope.
Option A, B, C and D therefore are false as they state facts about slope which are not obtainable from the given data.
Thus, "it cannot be determined whether the linear relationship between player height and number of points scored for basketball players in the coach's state is positive or negative "(Option E) is corect here.

A car journey is in two stages Stage1 the car travels 110 miles in 2 hours Stage 2 the car travels 44 miles at the same average speed as stage 1 Work out the time for stage 2 Give you answer in minutes.
9514 1404 393
Answer:
48 minutes
Step-by-step explanation:
The average speed for stage 1 is ...
speed = distance/time = (110 mi)/(2 h) = 55 mi/h
Then the time for stage 2 is ...
time = distance/speed = (44 mi)/(55 mi/h) = (4/5 h)(60 min/h) = 48 min
The time for stage 2 is 48 minutes.
Answer:
Solution :-We know that
SpeeD = Distance/Time
Speed = 110/2
Speed = 55 mi/hr
For, 2
Speed = 44/55
Speed = 4/5
Speed = 48 min

If $520 is borrowed for 290 days at 2.15% simple annual interest, how much will be repaid at the end of 290
days?
Step-by-step explanation:
Formula for simple interest
[tex]a = p(1 + rt)[/tex]
where a = final amount
p = principal amount
r = annual interest rate
t = time in years
given p = 520,
r = 2.15/100
t = 290/365 (1 year = 365 days)
[tex]a = 520(1 + ( \frac{2.15}{100} )( \frac{290}{365} )) \\ = 520 (1 + \frac{1247}{73000} ) \\ = 520( \frac{74247}{73000} ) \\ = 528.88 \: (2.dp)[/tex]

To a set of five grades with an average of 7.31, the following grades are added 4.47 and 9.15 What is the new average?
Answer:
New mean average of 7 grades = 7.17 (Approx.)
Step-by-step explanation:
Given:
Mean average of 5 grades = 7.31
Number of grades = 5
New grades = 4.47 and 9.15
Find:
New mean average of 7 grades
Computation:
Total of old grades = Mean average of 5 grades x Number of grades
Total of old grades = 7.31 x 5
Total of old grades = 36.55
Total of new grades = Total of old grades + 4.47 + 9.15
Total of new grades = 36.55 + 4.47 + 9.15
Total of new grades = 50.17
New mean average of 7 grades = 50.17 / 7
New mean average of 7 grades = 7.167
New mean average of 7 grades = 7.17 (Approx.)

If you apply the changes below to the quadratic parent function, f(x) = x?,
what is the equation of the new function?
• Shift 1 unit right.
• Vertically stretch by a factor of 5.
• Reflect over the x-axis.
O A. g(x) = (-5x + 1)2
O B. g(x) = -5(x + 1)2
O C. g(x) = 5x2 - 1
O D. g(x) = -5(x - 1)2
Answer:
The answer is A
Step-by-step explanation:
(D) g(x) = -5(x-1)² is the correct answer for the given changes in function.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
The starting parent function is f(x) = x².
To shift 1 unit right, we need to replace x with (x-1).
To vertically stretch by a factor of 5, we need to multiply the function by 5.
To reflect over the x-axis, we need to multiply the function by -1.
So the new function g(x) can be written as:
g(x) = -5(x-1)²
Therefore, the correct answer is (D) g(x) = -5(x-1)².
