find the weighted mean for three exams if the first one was worth 75 points and the student received a score of 70%, the second was worth 50 points and the student received a score of 80% and the third was worth 30 points and the student received a score of 95%?
The weighted mean for three exams is 78.1%.
Define weighted mean.The weighted mean is a form of mean that is computed by averaging all the products after multiplying the weight (or probability) connected to a specific event or result by its connected quantitative outcome. The difference between the weighted arithmetic mean and a regular arithmetic mean is that certain data points contribute more to the final average than others, as opposed to all data points contributing equally. In mathematics, the average value of the data is determined using the weighted mean. When calculating the weighted mean, the average value can be determined by giving various weights to some of the individual variables.
Given,
Weighted mean for student:
Weights = 155

The best package of beans to buy is 26 ounce costs $8.84
How to calculate the best package ?
The first step is to find the unit rate for each packages
package a
6= 1.96
1= x
cross multiply both sides
6x= 1.96
x= 1.96/6
x= 0.326
package b
15= 4.80
1= x
cross multiply both sides
15x= 4.80
x= 4.80/15
x= 0.32
package c
26= 8.84
1= x
cross multiply both sides
26x= 8.84
x= 8.84/26

Fill in the next two terms in the pattern. Enter your answers in the boxes. 0.16, 0.35, 0.54
ANSWER
0.73, 0.92
EXPLANATION
We want to fill the next two terms in the pattern.
The pattern given is:
0.16, 0.35, 0.54
There is a common difference in this pattern (the difference between two successive terms).
To find this, let us subtract the first term from the second:
0.35 - 0.16 = 0.19
This is the same for the third term subtracting the second term:
0.54 - 0.35 = 0.19
Therefore, the next two terms can be gotten by adding 0.19:
0.54 + 0.19 = 0.73
0.73 + 0.19 = 0.92
The next two terms are 0.73 and 0.92.

95.7%
Charlize will be left over with 95.6% of her total salary if her student loan payments are $325.00 per month for 144 months .
in the question ,
it is given that
Total salary of Charlize = $87655 .
since the pay is annual the student loan payment will also be for 12 months.
amount Charlize pays per month as student loan = $325
So , the amount Charlize spent on loan payment = $325×12
= $3900
Amount left with Charlize after deduction = $87655 - $3900
= $ 83755
So the percent of amount left with Charlize after deduction
= (amount left)/(total salary) × 100
Substituting the values
we get
percent of amount left with Charlize after loan deduction =(83755/87655)*100
= 0.955507*100
= 95.5507
rounding off to the nearest tenth
≈ 95.6 %
Therefore , Charlize will be left over with 95.6% of her total salary if her student loan payments are $325.00 per month for 144 months .

a spherical ball fits snugly inside a cylindrical jar, so that the ball touches the top and bottom of the jar, and the sides of the jar. the volume of the cylinder is $432 \pi.$ what is the volume of the sphere?
The volume of the sphere that snugly fits into the cylinder of volume 432π cube units is 288 cube units.
It is given that
The fall snugly fits inside the cylindrical jarThe ball touches the top and bottom of the cylindrical jarTherefore, from the image attached we can infer that
the diameter of the sphere and the cylinder is the sameLet the radius of the cylinder and the sphere be r units
Let the height of the cylinder be h units.
Hence h = 2r units
We know that the volume of the Sphere is 4/3πr³
The volume of a cylinder is πr²h
= πr² X 2r
= 2πr³ units cube
According to the problem,
2πr³ = 432π
Multiplying L.H.S with 2/3 gives us
4/3πr³ = 2/3 X 432π
or, 4/3πr³ = 288π
or, the volume of the sphere is 288π cube units
288π cube units

Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. The possibility of an event or outcome happening contingent on the occurrence of a prior event or outcome is known as conditional probability.
What Sets Conditional Probability Apart from Regular Probability?
The probability of one event happening is examined in probability. The relationship between two occurrences that could happen is examined through conditional probability.
Based on the likelihood that the first event will occur, the probability of the second event happening is examined. The likelihood of the preceding event is multiplied by the probability of the subsequent, or conditional, occurrence to determine the conditional probability.
Conditional probability examines the likelihood of a single event.

Quality Ts produces T-shirts for a $30 design fee plus a $6 charge per shirt printed.
The function rule for this scenario can be written in slope-intercept form as: y = 6x + 30.
How to Write a Function Rule?A function rule can be written in slope-intercept form using the unit rate or slope (m), and the starting value/initial value or y-intercept (b). The values of m and b, when determined, are simply plugged into the equation, y = mx + b.
We are given that the design fee that is charged by the cloth designer is a fixed fee of $30. This means that the starting value or y-intercept (m) is 30.
From the problem, we are also given that the additional charge per shirt printed is $6, this also implies that the slope or unit rate (m) of the function is 6.
To write a function rule in slope-intercept form, substitute m = 6 and b = 30 into y = mx + b:
y = 6x + 30.
The function rule for the cost of t-shirt produced based on the number of shirts is expressed as: y = 6x + 30.
