Question 1 The solution to 5 - 3x > 35 is either r > -10 or -10 > 2. Which solution is correct? Explain how you know. Edit View Insert Format Format Tools Table 12pt Paragraph BI U AY 2 T?
Answer:
x < -10
Step-by-step explanation:
Given the inequality 5 - 3x > 35
Subtract 5 from both sides
5 - 3x - 5> 35 -5
-3x > 30
Divide both sides by -3
-3x/-3 < 30/-3
x < -10 (note the change is sign)
hence the correct solution is x < -10

The numbers of points scored in each basketball game are 49, 36, 61, 64, 39, 41, 43, and 39.
In what percent of the games were at least 55 points scored?
Answer:
In 25% of the games at least 55 points were scored.
Step-by-step explanation:
Percentage:
Number of desired outcomes multiplied by 100 and divided by the number of total outcomes.
In this question:
8 total games
In 2 at least 55 were scores.
100*2/8 = 100/4 = 25%
In 25% of the games at least 55 points were scored.

day last week.
Based on this sample, which of the following is a 95% confidence interval for the proportion of all students at
the school who ate breakfast every day last week?
Choose 1 answer:
20+ 0.080
20 + 0.095
0.25 +0.080
Answer:

Step-by-step explanation:
The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.
Given thatFatimah wants to estimate the proportion of students at her school who ate breakfast every day last week.
She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.
We have to determineBased on this sample, which of the following is a 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week?
According to the questionShe takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.
[tex]\rm P = \dfrac{Sample \ space}{Total \ SRS}\\ \\ P = \dfrac{20}{80}\\ \\ P = \dfrac{1}{4}\\ \\ P = 0.25[/tex]
Therefore,
The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is
=[tex] = 1.96 \times \sqrt{\dfrac{0.25(1-0.25)}{80}}\\ \\ = 1.96 \times \sqrt{\dfrac{0.25\times 0.75}{80}}\\\\ = 1.96 \times 0.40\\\\ = 0.080[/tex]
Hence, The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.

in a mixture of one hundred liter of milk ans water 4:1 ratio of milk and water where is ratio of milk to water in the new mixture when 25% of the mixture is removed and the same amount of water is added?
Answer:
The milk to water ratio in the new mixture is 3:2.
Step-by-step explanation:
Given that in a mixture of one hundred liters of milk and water the ratio of milk and water was 4: 1, to determine what is the ratio of milk to water in the new mixture when 25% of the mixture is removed and the same amount of water is added, the following calculation must be performed:
(100/5) x 4 = 80
80 liters of milk
20 liters of water
80 x 0.75 = 60
20 x 0.75 = 15
15 + 25 = 40
60 + 40 = 100
Thus, the milk to water ratio in the new mixture is 3:2.

If L(2, 7) is an endpoint of a line segment, and M(8, 3) is the midpoint, find the other endpoint of the segment.
Answer:
Step-by-step explanation:
From L to M,
change in x-coordinates = 8-2 = 6
change in y-coordinates = 3-7 = -4
Extrapolate from M(8,3) to find the other end of the segment:
8 + 6 = 14
3 - 4 = -1
Endpoint of segment: (14,-1)
The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62
Answer:
About 34%
Step-by-step explanation:
Given that :
Mean, m = 59 ; Standard deviation, s = 3
Bulb replacement numbering between 59 and 62
For, x = 59
Zscore = (x - m) / s
Z = (59 - 59) / 3 = 0
For x = 62
Z = (62 - 59) / 3 = 1
P(Z < 1) - P(Z < 0)
0.84134 - 0.5
= 0.34134
About 34%
Using the graph below, what would the input (x-value) need to be for an output (y value) of 1?
Answer:
X = 2
Y = 1
The graph intersects at the exact point of (2,1)
The value of x or the input value is 2 for which the output or the value of y is 1.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have a graph of a line shown in the picture
As we can see the line passes through the points (3, 3) and (0, -3)
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The equation of the line passes through the points:
( y + 3) = (-3-3)/(0-3)[x - 0]
y + 3 = 2x
y = 2x - 3
Plug y = 1
1 = 2x - 3
2x = 3 + 1
2x = 4
x = 4/2
x = 2
Thus, the value of x or the input value is 2 for which the output or the value of y is 1.
