Answer:

Option (c) is correct.

Expression $7\frac{1}{5}-6\frac{2}{5}$ simplified to $\frac{4}{5}$

Step-by-step explanation:

Given : expression $7\frac{1}{5}-6\frac{2}{5}$

We have to find the value of the given expression $7\frac{1}{5}-6\frac{2}{5}$

Consider the given expression $7\frac{1}{5}-6\frac{2}{5}$

$7\frac{1}{5}=frac{36}{5}$

and $6\frac{2}{5}=\frac{32}{5}$

Thus, $7\frac{1}{5}-6\frac{2}{5}$ becomes

$\frac{36}{5}-\frac{32}{5}$

LCM (5,5) = 1

Thus, $\frac{36}{5}-\frac{32}{5}=\frac{36-32}{5}=\frac{4}{5}$

Thus, Expression $7\frac{1}{5}-6\frac{2}{5}$ simplified to $\frac{4}{5}$

<h3>The cost of purchasing baby chicks at $4.50 per chick represents proportional relationship</h3>

Solution:

in a proportional relationship, one variable is always a constant value times the other.

y = kx

Where, k is a constant

Option 1

The cost of purchasing hay for $26 a bale with a delivery charge of $30

Cost = $ 26 a bale + 30

This does not forms a proportional relationship

Option 2

The cost of purchasing baby chicks at $4.50 per chick

Let "x" be the number of chicks

Therefore,

$cost = 4.50 \times x$

Thus, this forms a proportional relationship

Option 3

The cost of purchasing fencing at $29 a linear foot with an installation fee of $300

cost = $ 29 a linear foot + 300

This does not forms a proportional relationship

Option 4

The cost of renting a backhoe for $79 per hour with a non-refundable deposit of $300

cost = $ 79 per hour + 300

This does not forms a proportional relationship

givi [52]

Answer: $5175.75

Step-by-step explanation:

The amount that is paid in total to buy the stock will be gotten through the addition of the cost of the shares and the commission paid. This will be:

= (200 × $25.75) + $25.75

= $5150 + $25.75

= $5175.75

Therefore, the total amount that is paid to buy the stock will be $5175.75.

Use the information given to answer the question. Vanessa and Moe record their quiz scores in music class for a semester. The do

Lorico [155]

Answer:

Vanessa records a total of 11 quiz scores

Moe records a total of 10 quiz scores

According to the data, Vanessa's mean score is 80

According to the data, Vanessa's median score is 85

The range of Moe's quiz score is 45

The interquartile range of Moe's quiz score is 16.25

Step-by-step explanation:

Vanessa's score is given in the dot plot

Moe's scores are; 75, 80, 90, 90, 95, 55, 100, 95, 85, 85

1) The number of quiz scores Vanessa records is given by the number of dots on the dot plot, n = 11 dots ≡ 11 quiz scores

2) The number of quiz scores Moe records is given by the number of data points, n = 10 data points ≡ 10 quiz scores

3) Vanessa's mean score = ∑x $_i$ /n

∑x $_i$ /n = (60 + 2× 65 + 75 + 4 × 85 + 2 × 90 +95)/11 = 80

Vanessa's mean score = 80

4) Vanessa's median score is the (11 + 1)/2 th score = Her 6th score = 85

Vanessa's median score = 85

5) The range of Moe's score = Her largest score - Her least score = 100 - 55 = 45

The range of Moe's score = 45

6) Sorting Moe's scores gives;

75, 80, 90, 90, 95, 55, 100, 95, 85, 85

55, 75, 80, 85, 85, 90, 90, 95, 95, 100

The first quartile, Q₁ = 11/4th score = 2.75th score = 75 + 0.75 × 5 = 78.75

The 3rd quartile, Q₃ = The 3/4×11 score = 8.25th score = 95 + 0.25 ×0 = 95

The interquartile range, I = Q₃ - Q₁ = 95 - 78.75 = 16.25

The interquartile range of Moe's quiz score = 16.25.
