Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
Using the normal distribution, it is found that a weight of 3125 grams would given a newborn a z-score of −0.75.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
Researching the problem on the internet, it is found that the mean and the standard deviation for the weight of newborns is given as follows:
Hence, the weight associated with Z = -0.75 is given by X:
X - 3500 = -0.75(500)
X = 3125.

Answer:
22, -10
Step-by-step explanation:
22-(-10)=32
22+(-10)=12
I found this by finding the difference between the two given numbers, 32 and 12.
Hope this helps friend.
Every number has factors. Some numbers share factors. To
simplify a fraction, divide the numerator and the denominator,
each separately, by the factors they share
in common. The only common factor, at the end, should be 1.
Here's an example:
I first divided by 9 and ten by x.
