Answer:
D) 0.0796
Step-by-step explanation:
Birth weights in Norway are normally distributed with a mean of 3570 g and a standard deviation of 500 g.
mean = 3570 and SD = 500
We need to find P(3500<x<3600)
P(3500<x<3600)= P(x=3600)- P(x=3500)
to find P(x=3600) we find z-score
Now use z-score table . z-score = 0.5239
P(x=3600)=0.6179
to find P(x=3500) we find z-score
Now use z-score table . z-score = 0.4443
P(x=3600)=0.4443
P(3500<x<3600)= P(x=3600)- P(x=3500)
P(3500<x<3600)=0.5239-0.4443 = 0.0796

Using the weighted mean, the coordinate of P is of P = -1.77.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, the points and weights are given as follows:
- D = 2 with a weight of 3.
- B = -6 with a weight of 9.
- A = -9 with a weight of 2.
- C = -1 with a weight of 3.
- E = 6 with a weight of 5.
<h3>What is the weighted mean?</h3>
The weighted mean is given by the <u>sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights</u>.
Hence, for the points this problem, the weighted mean is given as follows:
P = (2 x 3 - 6 x 9 - 9 x 2 - 1 x 3 + 6 x 5)/(3 + 9 + 2 + 3 + 5) = -1.77.
The coordinate of P is of P = -1.77.

Answer:
B
Step-by-step explanation:
$65×6%=$3.90
$3.90+$65=$68.90

Answer: The answer would be x=5/3
Step-by-step explanation:
First you would subtract 11 from both sides, cancelling out the 11 on the left while making 21-11=10. Your equation at this point would be 6x=10. Now you would divide by 6 on both sides making the answer x=5/3.
