Answer:

67.2 and 94.1

Step-by-step explanation:

Let x represent one number and y represent the other

their sum is

x + y = 161.3 and the difference

x - y = 27.9 now add two equations

x + y + x - y = 161.3 + 27.9

2x = 188.2 divide both sides by 2

x = 94.1 to find the other number subtract this from 161.3

y = 161.3 - 94.1

y = 67.2

Natali [406]

The temperature is 46°F

Step-by-step explanation:

Given the temperatures in F for the past four days as: 45, 38, 46, 35

The mean for the five days is 42 °F

Find the total temperatures with the mean of 42 in 5 days. Perform multiplication

42*5= 210 ° F

Sum of temperature in 4 days is 45+38+46+35=164 °F

The temperatures for the first day will be : 210°F-164°F=46°F

What is the IQR of 11,11.5,10.5,17,14.5,18,17,19

Vika [28.1K]

Ascending order :-

10.5 , 11 , 11.5 , 14.5 , 17 , 17 , 18 , 19

Median,

={(n/2)th + (n/2 +1)th}/2

={(4)th + (5)th}/2

=(31.5)/2

=15.75

I.Q.R.,

Median of lower half,

={(n/2)th + (n/2 +1)th}/2

={(2)th + (3)th}/2

=(22.5)/2

= 11.25

Median of upper half,

={(n/2)th + (n/2 +1)th}/2

={(2)th + (3)th}/2

=35/2

=17.5

I.Q.R. = 17.5 - 11.25 = 6.25

Tanzania [10]

Answer:

The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

Step-by-step explanation:

P.S - The exact question is -

Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs $\frac{3}{4}$ pound, a navel orange that weighs $\frac{5}{8}$ pound, and a pear that weighs 0.5 pound.

To find - What is the order of the fruit from least weight to the greatest weight ?

Proof -

Weight of apple = 0.45 pound

Weight of grapefruit = $\frac{3}{4}$ pound = 0.75 pound

Weight of navel orange = $\frac{5}{8}$ pound = 0.625 pound

Weight of a pear = 0.5 pound

As,

0.45 < 0.5 < 0.625 < 0.75

So, The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit
