The table shows the mean number of basketball goals made by four random samples of players from the school team during this year’s season. Sample # Sample Mean Number of Goals 1 7 2 4 3 5 4 8 Is a valid prediction for the mean of the population possible using these samples? No, there are not enough samples. Yes, the sample means are all less than 10. Yes, the variation of the sample means is small. No, the variation of the sample means is too great.

C. Yes, the variation of the sample means is small.
Step-by-step explanation:
edge
The mean of the population possible using these samples is; C. Yes, the variation of the sample means is small
What is a sample mean?Sample mean is an average of a set of data . And, the sample mean can be used to determine the standard deviation, central tendency, and the variance of a data set.
The sample mean can be applied to various uses, including calculating population averages.
Where, the sample variance is a measure of the degree to which the numbers in a list are spread out. And the numbers given are close to each other;
If the numbers in a list are all close to the expected values; the variance will be small and if they are far away, the variance will be more.
Hence, the correct option is C.

write an equation of a line (-4,-1) and is perpendicular to the line y=4/3x+6
y =
Answer:
y= -3/4x-2
Step-by-step explanation:
- perpendicular: opposite signs and reciprocal
m= -3/4
point-slope form: y-y1=m(x-x1)
y-(-1)= -3/4(x-(-4))
y+1= -3/4(x+4)
y+1= -3/4x -3
y= -3/4x-2

It is B (see the explanation)
Step-by-step explanation:
You can easily find this answer on a CASIO calculator (you just have to set it up for angles)
We just have to see which answer is the closest to 0.88295
A: 8/17 = 0.47059 5dp

Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)
Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5
Step-by-step explanation:
If the slope of line a is -4/3 and the slope of line b is 3/4 line a and line b are perpendicular
A: True
B: False
C: False most of the time
Answer:
hi! so for perpendicular it's negative reciprocal!
so is -4/3 and 3/4 negative reciprocals?
oh and remember reciprocals are flipped!
if you still don't get it let me know aha
Answer:
True
Step-by-step explanation:
e Whenever you need to find the slope of a line, it is always the reciprocal with the opposite sign. For example, if your slope was 5, your slope to make it perpendicular would be -1/5. If you had the slope of -8/5, the perpendicular sope would 5/8.

Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour

2.5 pounds of blueberries cost $11.25
11.25 pounds of blueberries cost $2.50
2.25 pounds of blueberries cost $0.50
1 pound of blueberries cost $5.00
Answer:
2.5 pounds of blueberries cost $11.25
Step-by-step explanation:
The answer cant be 2.25 pounds of blueberries cost $0.50 because x becomes before y and x is how many pounds of blueberries there are and y is the cost.

Which statement correctly describes the relationship between △JKL and △J′K′L′?
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a reflection across the x-axis, which is a rigid motion.
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a rotation of 90° counterclockwise about the origin, which is a rigid motion.
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a translation 5 units up, which is a rigid motion.
△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
Answer:
The is answer is the last one.
Step-by-step explanation:
I just took the test
The correct statement is
△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Translation, rotation, reflection, and dilation are the four primary categories of transformation.
According to the given graph we have noticed that there is reflection over x- axis.
And, also there is no shifting of units.
So, there is only the reflection over x- axis.
But, there is no option about reflection.
Hence, △JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
