Consider a set of data in which the sample mean is 73.4 and the sample standard deviation is 4.9. Calculate the z-score given that x = 69.5.
Round your answer to two decimal places.
Answer: the z-score is -0.80
Step-by-step explanation:
Given that;
mean μ = 73.4
standard deviation σ = 4.9
x = 69.5
z-score = ?
z = (x - μ) / σ
we substitute
z = (69.5 - 73.4) / 4.9
z = -3.9 / 4.9
z = - 0.7959 ≈ -0.80 { 2 decimal places }
Therefore, the z-score is -0.80

Answer:
1. -1/3
2. 3/4
3. 2
4. -9/0
5. 1
6. -6/4
Step-by-step explanation:
1. To find this numbers slope you have to go over and up (or down depending on where the line is going) You go over once and down three times to the next dot. This is why it is negative, because you go down
2. Same as number one you go over (Run) and up (Rise) . You go over 3 times and up 4. This makes it positive, since you are going up.
3. Stick to this formula (y2-y1)
(x2-x1)
-4-8
0-6 =-12/-6 =2
4. Same as 3
1-8
5-5 = -9/0
5. Go over 1 and up 1 this will equal 1/1 which is just 1.
6.
-2-4
-6-2 =-6/-8
This can be simplified down to -3/-4

In a three hour TV broadcast the commercials show 29% of the time. How many minutes of commercials are shown each hour? Round to the nearest tenth of a minute
Answer:
There are 17.4 minutes of commercials are shown each hour.
Step-by-step explanation:
An hour has 60 minutes.
So in 3 hours, there are 3*60 = 180 minutes.
The commercials show 29% of the time.
So we have 0.29*180 = 52.2 minutes, in total, of commercial.
Per hour, we have 52.2/3 = 17.4 minutes of commercial.

what is the acceleration of a car that has a mass of 300 kg and 1200N
what is the acceleration of a car that has a mass of 300 kg and 1200N
Answer:
well the acceleration produced will be
[tex]4ms { - }^{2} [/tex]
Step-by-step explanation:
the formula used here is
F = m × a
(where m = mass , a = acceleration and f = force )
so,
=》1200 N = 300 kg × a
=》a = 1200N ÷ 300 kg
=》a = 4 metre per second square

Step-by-step explanation:
scented candles:
(1/12) / (20/60) = 1/4 inches/ hour
unscented candles:
(1/6) / (30/ 60) = 1/3 inches/ hour

B.
15%
C.
23%
D.
37%
Answer:
Step-by-step explanation:
B 15%
Answer: The correct answer is D) 37%
Step-by-step explanation:
We can use our binomial model equation with all the relevant information to solve this problem simply. We just need to dissect the problem a bit to find relevant information. We know that out of 16 batteries in a pack (the number of trials in this case) we want to find the possibility of 1 of them (the number of successes) to be defective with a defective rate of 5% or 0.05. We simply input the data into our binomial formula given and solve for our answer of 37% I hope this answer has been of use.

Jane can fill
cases and will have
bottles left.
Answer:
a) 265 case
b) 4 bottles
Step-by-step explanation:
The number of bottles remaining = total number of bottles - total number of bottles placed in cases
The number of bottles remaining = 8500 - 2136
The number of bottles remaining = 6364 bottles
From the table, we can see that water is filled at 24 bottles per case. Let x be the number of cases, hence:
24 bottles per case * x case = 6364 bottles
24x = 6364
x = 6364
x = 265.16
Therefore the number of cases filled = 265.
265 cases can contain 6360 bottles
b) number of bottles remaining = 6364 bottles - (24 * 265 case) = 4 bottles

illustrates whather the two ratios are equal or not using cross 3/27, 1/9
Answer:
They are equal
Step-by-step explanation:
Given
[tex]\frac{3}{27}\ and\ \frac{1}{9}[/tex]
Required
Determine if they are equal
We start by equating both:
[tex]\frac{3}{27} = \frac{1}{9}[/tex]
Cross Multiply
[tex]3 * 9 = 1 * 27[/tex]
[tex]27 = 27[/tex]
Because both sides of the equation are equal, then the ratios are equal
