Answer:
Landing on Blue: Likely
Landing on Green: Impossible
Landing on Yellow: Unlikely
Step-by-step explanation:
Blue: 50% chance
Green: 0% chance
Yellow: 12.5% chance
Answer:
So blue is 4/8 which should be as likely as not then red is 3/8 could be unlikely since it is 38 percent. then yellow is for sure unlikely since it is just 1/8

Justin likes to get 7 hours of sleep. He woke up after sleeping for 5 1/3 hour. How many more hours does he need to get the amount of sleep he likes?
Answer:
He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours
Step-by-step explanation:
Justin likes to get 7 hours of sleep.
He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins
Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.
1 hour = 60 minutes
1/3 hours = 60/3 = 20 minutes
Hours Minutes
7 00 when we borrow 1 hour we borrow 60 minutes
5 20
1 40
He needs 1 hour 40 minutes more to get the amount of sleep he likes
or 1 2/3 hours

A 2-yard piece of cotton cloth costs $1.32. What is the price per foot?
Answer:
$0.22 per foot
Step-by-step explanation:
So for context, 1 yard is 3 feet. So 2 yards is 6 feet. With this, by dividing $1.32 by 6, you can get the price per foot:
1.32 / 6 ---> $0.22 per foot.
Scores on an IQ test are normally distributed. A sample of 25 IQ scores had standard deviation of 8. The developer of the test claims that the population standard deviation of 15. Do these data provide sufficient evidence to significance? Use =0.05α=0.05 . Test by using a confidence interval. Show step1-step3.
Answer:
Yes, the data provides sufficient evidence at 0.05 level of significance
Step-by-step explanation:
n = 25
s = 8
σ = 15
χ² = (n - 1)s² / σ²
χ² = (25 - 1)*8² / 15²
χ² = (24 * 64) / 225
χ² = 6.827
The critical value at 0.05 ; df = 25 - 1 = 24
12.4012 and 39.3641
Reject H0 if χ² < 12.4012 or if χ² > 39.3641
Since,
χ² < 12.4012 ; We reject H0 ;

[tex]\frac{n}{85}= \frac{34}{170}[/tex]
Step-by-step explanation:
[tex]\frac{n}{85}= \frac{34}{170}[/tex]
n · 170 = 34 · 85
170y = 2890
170y ÷ 170 = 2890 ÷ 170

PLEASE DON'T GIVE A LINK OR DELETE THE ANSWER BECAUSE THIS IS MY SECOND TIME POSTING THIS SO PLS PLS PLS GIVE A PROPER ANSWER TO ALL OF THE PICTURES.
Answer:
Alright, with this, its essentially asking for you to plug in X into each equation for the answer.
With the first box, it asks for y = 5 - x, given the x = -2.
y = 5-x
y=5-(-2)
y=5+2
y=7
With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.
y = 5-x
6 = 5-x
x+6= 5
x=-1
With the third one, its the same thing as with the first box.
y = 5-x
y = 5-0
y = 5
Same thing with the fourth one.
y = 5-1
y = 4

Answer:
b. the slopes of both functions are positive
Step-by-step explanation:
hope this helps :)
Answer:
C. The slope of function A is positive and the slope of function B is negative.
Step-by-step explanation:
For this problem, you need to determine the slope of each function.
For function A:
You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.
So the slope for function A is 1/4.
For function B:
You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)
Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].
Therefore, the slope of function A is positive and the slope of function B is negative.

A line passes through points (2,5) and (5, 14). What is the slope of this line?
We know that:
Slope of a line = change in y coordinate / change in x coordinate
We are given:
First point = (2,5)
Second point = (5, 14)
Calculating the change in y coordinate:
change in y (also represented by Δy) = second y - first y
Δy = 14 - 5
Δy = 9
Calculating the change in x coordinate:
Δx = second x - first x
Δx = 5 - 2
Δx = 3
Slope of the line:
Slope = (Δy) / (Δx)
Slope = 9 / 3 [replacing the values]
Slope = 3
