Pine trees and juniper trees are common to the San Bernardino
mountains. Pine trees have a mean height of 52 meters with a
standard deviation of 3 meters. Juniper trees have a mean
height of 22 meters with a standard deviation of 5 meters.
(a) At the base of a trail, there is a 48-meter-tall pine tree and a
33-meter-tall juniper tree. Calculate the Z-score for each of
these trees.
If necessary, round your answers to the nearest 2 decimal
places. Write both answers in the text box below.
Answer:
Z-score = 0.9450
Step-by-step explanation:
Step(i):-
mean height of pine tree (x₁⁻) = 52
standard deviation of pine tree σ₁ = 3
Mean height of Jupiter tree ((x₂⁻) = 22
standard deviation of Jupiter tree σ₂ = 5
Size of first sample n₁ = 48
size of second sample n₂ = 33
Step(ii):-
Z-score
[tex]Z = \frac{x^{-} _{1} -x^{-} _{2} }{\sqrt{\frac{S.D^{2} }{n_{1} }+\frac{S.D^{2} }{n_{2} }} }[/tex]
[tex]Z = \frac{52 -22 }{\sqrt{\frac{3^{2} }{48 }+\frac{5^{2} }{33 }} }[/tex]
Z = 0.9450
The graph below shows the hours students spent studying and their language arts test scores.
Hours Spent Studying vs. Language Arts Test Scores
A graph has hours spent studying on the x-axis and language arts test scores on the y-axis. A line goes through points (2.5, 60) and (5, 80).
Based on trend line on the graph, what is the expected test score for a student who did not study?
0.5
8
40
45
Answer:
cccc
Step-by-step explanation:
it is correct on edge
The expected test score for a student who did not study is 40.
Option C is the correct answer.
We have,
Given that the line on the graph passes through the points (2.5, 60) and (5, 80), we can use this information to estimate the expected test score for a student who did not study.
Let's calculate the slope of the line using the two given points:
Slope = (change in y)/(change in x)
= (80 - 60)/(5 - 2.5)
= 20/2.5
= 8
The slope of the line is 8, which indicates that for every additional hour spent studying, the test score increases by 8 points.
Since we are looking for the expected test score for a student who did not study (0 hours spent studying), we can substitute x = 0 into the equation of the line to find the corresponding y value (test score).
y = mx + b (where m is the slope and b is the y-intercept)
Using the given points, we can find the y-intercept (b) by substituting one of the points into the equation:
60 = 8(2.5) + b
60 = 20 + b
b = 60 - 20
b = 40
The equation of the line is y = 8x + 40.
Now, substitute x = 0 into the equation to find the expected test score:
y = 8(0) + 40
y = 0 + 40
y = 40
Thus,
The expected test score for a student who did not study is 40.

If you are adding two positive integers, the sum will be positive.
3 + 5 = 8
If you are adding two negative integers, the sum will be negative.
-3 + (-5) = -8
If you are adding a negative integer and a positive integer, find the difference of the
absolute values. The sum will have the sign of the addend with the greater absolute value.
-3 + 5 = 2

Danny took a math test and got 35 correct and 10 incorrect answers. What was the percentage of the correct answers? (Round your answer the the nearest hundredth)
A student earned a grade of 80% on a math test that had20 problems. How many problems on this test did the student answer correctly? (round to the nearest whole number)
Answer:
1. 78%
2. 16
Step-by-step explanation:
35 + 10 = 45
Danny got 35/45 answers correct.
Divide 35 into 45
35 ÷ 45 = .777777778
.777777778 ≈ .78
To convert a decimal to a percentage, move the decimal point two spaces behind.
.78 = 78%
Danny got 78% of the answers correct.
80% = .8 = [tex]\frac{8}{10}[/tex]
Multiply [tex]\frac{8}{10}[/tex] by 20 to get the answer
[tex]\frac{8}{10}[/tex] × [tex]\frac{20}{1}[/tex] = [tex]\frac{160}{10}[/tex]

A store buys a camera for $80 and decides to markup the price 35%. How much does the camera sell for?
Answer:
The camera is sold for $ 59.26.
Step-by-step explanation:
From the statement we understand that the new price of the camera ([tex]C'[/tex]) is calculated by:
[tex]C' = \frac{C_{o}}{\left(1+\frac{r}{100} \right)}[/tex] (1)
Where:
[tex]C'[/tex] - Price after increase, measured in US dollars.
[tex]r[/tex] - Increase rate, expressed in percentage.
If we know that [tex]C_{o} = 80\,USD[/tex] and [tex]r = 35[/tex], then the new price of the camera is:
[tex]C' = \frac{80\,USD}{1+\frac{35}{100} }[/tex]
[tex]C' = 59.26\,USD[/tex]
The camera is sold for $ 59.26.

Answer:
X = 38° and w = 65°.
Step-by-step explanation:
Hey there!
Looking through figure, we get;
(3x + 1)° = (2x + 9)° + 30° { Exterior angle of triangle is equal to the sum of opposite adjacent interior angles}
(3x + 1)° = 2x + 9° +30°
or, 3x - 2x = 39° - 1°
x = 38°
X = 38°
Therefore, x = 38°
For w:
(3x + 1)° + w = 180° (being linear pair)
(3*38+1 )°+ w = 180°
115°+ w = 180°
w = 180° -115°
Therefore, w = 65°

What is the product of –24 and 35?
Answer:
-840
Step-by-step explanation:
"Product" means to multiply, so you multiply -24 by 35. Since -24 has a negative, negative times a positive will equal a negative number.
(Negative times negative is positive.)
(Negative times positive is negative.)
(Positive times positive is obviously positive.)
Using these simple rules, we can do this:
Simply multiply -24 by 35, or you can multiply 24 by 35 which is 840, but DON'T forget to put a negative symbol!
Hope this helps! Let me know if there is anything else.

What is an equation of the line that passes through the point (6, 7) and is parallel to
the line 2x - 3y = 9?
Answer:
Step-by-step explanation:
If it is parallel with the line 2x-3y=9
Both of them have same slope so
2x-3y=9 turn this into slope intercept form first
-3y=9-2x
Y=9/-3 + -2x/-3
Y=2/3x - 3 the slope of this equation is ⅔
So our new equation will be
Y=⅔x +b
Since (6,7)
On the line
6=⅔(7)+b
b= 6-14/3=4/3
Y=⅔x+4/3 (slope intercept form)
3y-2x=4 ( general equation of line )
The equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19
The equation of a line in point slope form is expressed as
y-y0 = m(x-x0)
m is the slope of the line
(x0, y0) is the point on the line.
Given the equation 2x - 3y = 9
Rewrite in standard form y = mx + b
-3y = -2x + 9
y = 2/3 x - 3
Compared with the standard, the slope of the line is 2/3
Substitute the slope and the point into the point slope equation.
y - 7 = 2/3 (x - 6)
3(y-7) = 2(x-6)
3y - 21 = 2x - 2
3y - 2x = 19
Hence the equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19
