The mean and standard deviation of the sample data collected on continuous variable are -0.25 and 0.03, respectively. The following table shows the
relative frequencies of the data in the given intervals.

-0.34 < x < -0.31
-0.31 <<< -0.28

Based on the table, do the data support the use of a normal model to approximate population characteristics?
A Yes, because the sum of the relative frequencies is 1.00.
B
Yes, because the distribution of relative frequencies is very close to the empirical rule for normal models.
с
No, because the values are negative and normal models are used for positive values.
D
No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
E
No, because the sample size and the population parameters are not known.
Answer:
B
Step-by-step explanation:
I know because I know that how
The correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
To determine if the data supports the use of a normal model to approximate population characteristics, we need to examine the relative frequencies and see if they exhibit a bell-shaped or normal distribution.
Looking at the table, we see that the relative frequencies are not symmetrical and do not follow the empirical rule for normal models.
The largest relative frequency is in the interval from -0.28 to -0.25, and the frequencies decrease as we move away from this interval. Additionally, there are negative values in the data, which is not a characteristic of normal models.
Therefore, the correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 0.425 kg box was on sale for $3.59, the 0.74 kg box was on sale for $4.88, and the 0.95 kg box was on sale for $7.29. Which box of cookies was the best buy? Explain your reasoning. To get you started: 3.59 : 0.425 1kg/ 0.425kg= 2.35 0.425 x 2.35= 1kg $3.59 x 2.35= $8.44 3.59 : 0.425 -> $8.44 : 1kg
Answer:
The best buy is the 0.74 kg box
Step-by-step explanation:
Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.
We find the unit price for 1 box
a) The 0.425 kg box was on sale for $3.59
= 1 kg = $3.25/0.425
= $7.6470588235
b) the 0.74 kg box was on sale for $4.88,
1 kg = $4.88/0.7$
= $6.5945945946
c) the 0.95 kg box was on sale for $7.29.
1 kg = $7.29/0.95
= $7.6736842105
Which box of cookies was the best buy?
The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.

Lisa is buying a computer for $1,500. The sales tax rate is 8.5%. Which expression should be used to calculate t, the total cost for the computer including tax?
Answer:
t=$1627.5Step-by-step explanation:
Step one:
given data
price of computer= $1500
sales tax= 8.5%
Step two
Let us compute the amount in tax
tax= 8.5/100*1500
=0.085*1500
=$127.5
Let the total cost be t
hence
t=1500+0.085*1500
t=1500+127.5
t=$1627.5

Find the missing angle
Answer: 137degrees
Step-by-step explanation:
So we know that a complete angel has 360 degrees within. So in this case, all we need to do is use 360 and subtract 167 and 56 from it.
360-167-56= 137
Hey there!
The answer is 109
We can see that both angles make 167, so 167 - 56 = 109 is remaining angle

Express in the form 1: n.
Give n as a decimal.
8 : 6
please help
Answer:
n = 0.75
1 : 0.75
Step-by-step explanation:
To get from 8 to 1, you have to divide by 8. You do that to the number 6.
6/8 = 3/4 = 75/100.
Therefore, n = 0.75.
slope of 0 and passes through (7, 4)
Answer:
y = 4
Step-by-step explanation:
Assuming you require the equation of the line.
A line with a slope of zero is a horizontal line parallel to the x- axis, with equation
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (7, 4 ) with y- coordinate 4, thus
y = 4 ← equation of line
