Answer 1
Answer:

Answer:

Step-by-step explanation:

You can solve it by substitution, by setting the first equation to y=1-x.

Replace the y in the equation by y=1-x.

4x + 3(1-x) = 8.

Distribute the 3.

4x + 3-3x = 8

Combine like terms.

x + 3 = 8

x =5

Plug 5 into y=1-x.

y=1-5

y= -4

The first quartile of a data set is 51, and the third quartile is 67. Which of these values in the data set is an outlier?A. 49
B. 83
C. 93
D. 29

Answers

Given:
Quartile 1 = 51
Quartile 3 = 67

Interquartile range = Q₃ - Q₁
IQR = 67 - 51
IQR = 16

Inner fence of the data set:
16 x 1.5 = 24

67 + 24 = 91
51 - 24 = 27

Boundaries of inner fence are 27 and 91

16 x 3 = 48

67 + 48 = 115
51 - 48 = 3

Boundaries for outer fence are 3 and 115

C. 93 is an outlier. It is a minor outlier based on the boundaries of the inner fence.

a lion runs 50 miles per hour in pursuit of a zebra running at 40 miles per hour. If the initial distance between them was a quarter of a mile,how long will it take for the lion to catch the zebra?

Answers

Let X = the length of time for the lion to catch up with the zebra.
50X = .25 + 40X
10X = .25
X = .25/10 = .025 hr

.025 hr x 60 min/1hr = 1.5 minutes

When the queen counted her jewels, she found that she had five pearls for each diamond, two opals and three rubies for each diamond, and two emeralds for each opal. If she has three diamonds, how many jewels does she have altogether?

Answers

I believe she would have 45 gems total

3 diamonds

5 pearls per diamond = 15 pearls

2 opals and 3 rubies per diamond= 6 opals and 9 rubies

2 emeralds per opal= 12 emeralds

3+15+6+9+12= 45 gems total
