Answer:
-3.8
Step-by-step explanation:
The temperature when Daria goes to bed was -3.8° F.
What is subtraction?To subtract means to take away from a group or a number of things. When we subtract, the number of things in the group reduces or becomes less.
Given that, When Daria gets to school, the temperature is 5.7 °F. The temperature changes by -9.5 °F by the time she goes to bed.
5.7 - 9.8 = -3.8
Hence, The temperature when Daria goes to bed was -3.8° F.

Wich ordered pair is a solution to the followimg inequality?
[tex]y\leq \frac{2}{5}x-2[/tex]
(5,0)
(0,5)
(-2,5)
(-5,2)
Answer:
Option A: (5,0)
Step-by-step explanation:
Given
[tex]y \leq \frac{2}{5}x-2[/tex]
Required
Select an ordered pair
Option A: (5,0)
This means
[tex]x = 5[/tex] [tex]y = 0[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]0 \leq \frac{2}{5} * 5 - 2[/tex]
[tex]0 \leq 2 - 2[/tex]
[tex]0 \leq 0[/tex]
This is a true statement.
Option B: (0,5)
This means
[tex]x = 0[/tex] [tex]y = 5[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]5 \leq \frac{2}{5}* 0 -2[/tex]
[tex]5 \leq 0 -2[/tex]
[tex]5 \leq -2[/tex]
This is a false statement.
Option C: (-2,5)
This means
[tex]x=-2[/tex] [tex]y = 5[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]5 \leq \frac{2}{5}* -2 -2[/tex]
[tex]5 \leq \frac{-4}{5} -2[/tex]
[tex]5 \leq \frac{-4-10}{5}[/tex]
[tex]5 \leq \frac{-14}{5}[/tex]
[tex]5 \leq -2.8[/tex]
This is a false statement.
Option D: (-5,2)
This means
[tex]x=-5[/tex] [tex]y = 2[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]2 \leq \frac{2}{5}* -5 -2[/tex]
[tex]2 \leq -2 -2[/tex]
[tex]2 \leq -4[/tex]
This is a false statement.
Only option A represents a true statement,
Hence, option A is a solution to the inequality

Which choice could be used in proving that the given triangles are similar?
Answer: . To prove triangles are similar, you need to prove two pairs of corresponding angles are congruent
Step-by-step explanation:
SSS similarity postulate
The SSS similarity postulate says that if the lengths of the corresponding sides of two triangles are proportional then the triangles must be similar.
In the given figure , we have two triangles ΔABC and ΔXYZ such that the corresponding sides of both the triangles are proportional.
i.e.
Then by SSS-similarity criteria , we have
ΔABC ≈ ΔXYZ

A quality control engineer is interested in estimating the proportion of defective items coming off a production line. In a sample of 100 items, 55 are defective. The lower bound of a 99% confidence interval for the proportion of defectives is ________.
Answer:
The lower bound of a 99% C.I for the proportion of defectives = 0.422
Step-by-step explanation:
From the given information:
The point estimate = sample proportion [tex]\hat p[/tex]
[tex]\hat p = \dfrac{x}{n}[/tex]
[tex]\hat p = \dfrac{55}{100}[/tex]
[tex]\hat p[/tex] = 0.55
At Confidence interval of 99%, the level of significance = 1 - 0.99
= 0.01
[tex]Z_{\alpha/2} =Z_{0.01/2} \\ \\ = Z_{0.005} = 2.576[/tex]
Then the margin of error [tex]E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1-\hat p)}{n}}[/tex]
[tex]E = 2.576 \times \sqrt{\dfrac{0.55(1-0.55)}{100}}[/tex]
[tex]E = 2.576 \times \sqrt{\dfrac{0.2475}{100}}[/tex]
[tex]E = 2.576 \times0.04975[/tex]
E = 0.128156
E ≅ 0.128
At 99% C.I for the population proportion p is: [tex]\hat p - E[/tex]
= 0.55 - 0.128
= 0.422
Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422

The color distribution of Skittles is the following: 10% blue, orange, and green each, 23.3333% yellow, red, and purple each. In a bag, there were 137 red Skittles, 39 orange ones, 130 yellow ones, 39 green ones, 43 blue ones and 112 purple ones. Do the Skittles in the bag match the required color distribution?
Answer:
No
Step-by-step explanation:
Given that:
Percentage of blue, orange and green = 10%
Percentage of yellow, red and purple = 23.3333%
Number of skittles in bag by color :
Red = 137
Orange = 39
Yellow = 130
Green = 39
Blue = 43
Purple = 112
According to the color distribution :
Number of blue, orange and green should be the same and also number of yellow, red and purple skittles must be the same.
Total number of skittles :
(137 + 39 + 130 + 39 + 43 + 112) = 500
10% of the total = 0.1 * 500 = 50
Hence,
We should have 50 blue, orange and green skittles
23.33333% of total = 116.666 (about 117 skittles of yellow, red and purple color)

Jay has spent 3/8 of his life working for his current company. If Jay has been 8 3working for his current company for 15 years, how old is he?
Answer:
40 years old
Step-by-step explanation:
If Jay has spent 3/8 of his life working for his current company and it is stated that he has been at the current company for 15 years, we can divide 15 years by 3 to find out how much a single part of the fraction (1/8) is.
15 / 3 = 5 years
5 years = 1/8
Now that we know how many years is a single part of his life we simply multiply this value by 8 to calculate how many years would equal his total life or in other words how old Jay currently is.
5 years * 8 = 40 years old
The LA Dodgers hit the most homeruns in 2014. The number of homeruns accounted for 6% of the entire major League baseball homerun count. If 583 total homeruns were hit, approximately how manu did the LA Didgers hit
Answer:
35 homeruns
Step-by-step explanation:
583*0.06=349.8-->34.98-->35
Answer:
The LA Dodgers hit 35 homeruns approximately in the league in year 2014.
Step-by-step explanation:
Given that:
Percentage of homeruns hit by LA Dodgers = 6% of the entire League
Total homeruns hit in the league = 583 homeruns
Homeruns hit by LA Dodgers = [tex]\frac{6}{100}*583[/tex]
Homeruns hit by LA Dodgers = 0.06 * 583
Homeruns hit by LA Dodgers = 34.98
Hence,
The LA Dodgers hit 35 homeruns approximately in the league in year 2014.

Answer:
Step-by-step explanation:
tan(16)=125/a
tan(16)=35.8 (DC)
tan(7)=125/a
tan(7)=15.3
35.8-15.3=20.5
Sorry if that's incorrect, my best is 20.5 feet.
======================================================
Work Shown:
Let
x = length of AD in feet
y = length of DC in feet
x and y are positive real numbers.
For now, focus on triangle BCD. Ignore point A and its associated angle.
tan(angle) = opposite/adjacent
tan(D) = BC/DC
tan(16) = 125/y
y*tan(16) = 125
y = 125/tan(16)
y = 435.926805480113
y = 435.926805
The value of y is approximate
Now focus on triangle ABC. Ignore point D and its associated angle.
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = BC/(AD+DC)
tan(7) = 125/(x + y)
(x+y)*tan(7) = 125
x*tan(7) + y*tan(7) = 125
x*tan(7) = 125 - y*tan(7)
x = ( 125-y*tan(7) )/( tan(7) )
x = ( 125-435.926805*tan(7) )/( tan(7) )
x = 582.116498496824
x = 582
The distance from A to D is approximately 582 feet.
