packages of sugar bags for sweeter sugar inc. have an average weight of 16 ounces and a standard deviation of 0.2 ounces. the weights of the sugar bags are normally distributed. what is the probability that 16 randomly selected packages will have a sample mean weight in excess of 16.075 ounces?
0.0668 is the probability that 16 randomly selected packages will have a sample mean weight in excess of 16.075 ounces.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. For instance, the theoretical chance of getting a head when tossing a coin is 12. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Write Proportion Statement and find the missing sides of the polygon.
The lengths of the sides AN, PM, and MO of the given polygons are 26, 40, and 96, respectively.
We are given two triangles. The vertices of the first triangle are A, N, and T. The vertices of the second triangle are P, O, and M. Both the triangles are right-angled. The triangles are similar to each other. The lengths of the sides AT and TN are 10 and 24, respectively. We will use the Pythagorean theorem to find the length of side AN.
AN = √[(10)² + (24)²] = √(100 + 576] = √676 = 26
Now, as we know the triangles are similar, the lengths of the corresponding sides must be in the same proportion. The ratio is calculated as given below.
r = PO/AN = 104/26 = 4
The length of the side PM is equal to r*AT = 4*10 = 40. The length of the side MO is equal to r*TN = 4*24 = 96.

Amina has a bag of 6 black balls and 4 green balls. Hamad has a bag of 3 black balls and 5 green balls. If one ball is drawn from each bag, the probability that one is black and one is green is 0.525.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely is that a proposition is true.
Amina has a bag of 6 black balls (B1) and 4 green balls (G1).
Hamad has a bag of 3 black balls (B2) and 5 green balls (G2).
∴ Probability of getting one black and one green ball
= B1G2 + G1B2
= 6/10 × 5/8 + 4/10 × 3/8

The probability of getting one black and one green ball if one ball is drawn from each bag is 0.525.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Amina has 6 black balls and 4 green balls in her bag. Hamad has three black balls and five green balls in his bag.
Amina has 6 black balls (B1) and 4 green balls in her bag (G1).
Hamad has 3 black balls (B2) and 5 green balls in his bag (G2).
So, the probability of receiving one black and one green ball:
= B1G2 + G1B2
= 6/10 × 5/8 + 4/10 × 3/8
= 30/80 + 12/80

9 7 59 families are asked whether they have a cat (C) or a dog (D). 26 only have a cat. 14 only have a dog. 11 have both a cat and a dog. (a) Show this information on the Venn diagram. ● ● E C D (b) (i) How many of the families do not have a cat or a dog? (b)(i) D (ii) Write your answer in the correct place on the Venn diagram. (c) One of the families is chosen at random. Write down the probability that they have a dog.
8 families do not have cat or dog. And the probability of a family having a dog is 0.42
Here Given that,
We have total 59 families.
26 only have cat.
14 only have a dog.
And 11 have both cat and a dog
Now, we will show this information on Venn diagram
for Venn diagram see the attachment.
Now, we can say that 26+14+11=51 families have pets at home.
So, we will find out that how many families do not have cat or dog
So,
we have 59 total families and from 59 families 51 have cat or a dog or both at home.
So,
Families do not have cat or dog = 59-51
Families do not have cat or dog = 8
therefore,
8 families do not have a cat or a dog.
Now, we will choose one family and find out the probability of that family having a dog.
So, we have 59 total families and out of 59 families 14+11= 25 families have a dog at home.
So,
The probability of a family having a dog =(families that have a dog)/(total families)
The probability of a family having a dog =25/59
The probability of a family having a dog =0.42

Jennine estimates that each step she takes is 18" long and that she takes 1550 steps
per block. How many blocks must she walk if she wants to walk 5 miles?
Answer: Jennine must walk 11.36 blocks.
Step-by-step explanation:
Since each step is 18" long and she takes 1550 steps per block, a block must equal to 1550*18", or 27,900".
27,900" is roughly 0.44 miles.
Therefore 5mi. /0.44mi. = ~11.36 blocks
Rachel paid 46 in tax for the money he earned a a camp counelor. How much money did rachel earn
Rachel earned an amount of $ 920
Given in the question,
5% × n = $46
5/100 × n = $46
0.05 × n =$46
0.05/0.05 × n = 46/0.05
Hence the amount is n = $920
Income that is earned comes under total earnings after taxes are deducted which one has already paid. Some of the income which is earned can include union strike benefits, specific retirement pensions, and long-term disability benefits. An expense that is removed or subtracted from the income of the person who is paying the taxes in order to lower the income which is earned by the person so that it is subjected to lower tax subtraction is known as deduction.

The inequality to determine when the cost of viewing n videos using

Plan A is less expensive when n is greater than 2.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Two monthly plans:
Plan A:
Cost per video = $3
Flat rate per month = $8
Plan B:
Cost per view = $5
Flat rate = zero
The inequality to determine when the cost of viewing n videos using
plan A is less than the cost of viewing n videos using plan B.
8 + 3n < 5n
Solving for n.
8 < 5n - 3n
8 < 2n
8/4 < n
n > 2
This means when n is greater than 2 we get,
The cost of viewing n videos using plan A is less than the cost of viewing n videos using plan B.
Thus,
