calculate the estimate of the mean height of the students in cm and explain your answer
Answers
Step-by-step explanation:
we find the average height of each height first,
t¹= (120+124)/2
=244/2
=122
t²= (124+128)/2
t²= 252/2
t²= 126
t³= (128+132)/2
t³= 260/2
t³= 130
t⁴= (132+136)/2
t⁴= 268/2
t⁴ =134
t⁵= (136+140)/2
t⁵= 276/2
t⁵= 138
so multiplying each height by its frequency we can find the total height, so we have..
total height= (122*7)+(126*8)+(130*13)+(134*9)+(138*3)
= 854+1008+1690+1206+414
= 5172
mean height = total height/total frequency
= 5172/40
=129.3

A package of nuts weights 3/4 of a pound. One serving size is 1/8 of a pound, how many servings in the package?
Answers
Answer: 6 servings
Step-by-step explanation:
One serving is 1/8 of a pound.
One package is 3/4 of a pound.
The number of servings therefore will be the number of times that 1/8 can go into 3/4.
= (3/4) / (1/8)
= (3/4) * (8/1)
= 6 servings

Tyson got a $15 gift card to use on song and movie downloads to his tablet. Each movie, m, costs $5 and each song, s, costs $1. Tyson's mom said he must use fewer than 10 downloads and that his total cost could not exceed the $15 amount on the gift card. Which of the following graphs shows the solution set of the system of inequalities?
Answers
Answer:
c
Step-by-step explanation:
bla bla bla
The solution to the inequality m + s = 10 and 5 m + 1s = 15 is shown in the graph attached below, and as it can be seen the coordinated of intersections are (8.75, 1.25), so option C is correct.
What is inequality?Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal
Given:
Total balance on card = $15,
The cost of each movie = $5,
The cost of each song = $1
The number of downloads = 10,
Write the equation as shown below,
m + s = 10 and 5 m + 1s = 15
Here m is the number of movies and s is the number of songs,
Solve the equation by elimination method,
m = 5/4 = 1.25 and s = 35/4 = 8.75
As you can see, the value of the intersection of inequalities is (8.75, 1.25),
the graph is attached below.
