A principal at a large high school wants to estimate the number of days freshmen regularly ride the bus to school.
The principal randomly selects 35 freshmen and asks them how many days per week they ride the school bus. The
principal constructs a 90% confidence interval for the true mean number of days freshmen ride the bus to school per
week. Which of the following would decrease the margin of error?
O using a sample of size 30
O using a sample of size 40

Answer:
it is linear
Step-by-step explanation:
A line passes through the points (-10, -3) and (-5, 1). What is the slope of the line?
Answer:
m= 4/5
Step-by-step explanation:
use the formula (y2 - y1)/ (x2 - x1)
(-10, -3) (-5, 1)
1-( -3)/-5-( -10)= 4/5
whats the value of x
A 95
B 105
C 75
D 85
Answer:
D. 85
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.
180 - 40 - 55 = 85
Answer:
85 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180, so we can set up an equation
x+40+55=180
Now all we need to do is to subtract 40 and 55 from both sides
x+55=180-40=140
x=140-55=85
x=85
Which set of ordered pairs represents y as a function of X? a{(-9, 2), (0, 6), (1, -2), (-3, 6)} b{(-1,0), (4, 3), (-7, -3), (-1, -8)} c{(3, 2), (-4,-2), (3, 1), (-4,1)} d{(5, 4), (2, 3), (1, 1), (2,4)}

What additional information would be necessary to prove that the two triangles, XBY and ZAY, are
congruent?
Answer: Congruent triangles have congruent corresponding sides.
(Note): This is not the correct answer..This is an Example. :)
Step-by-step explanation: part a) draw two triangles, translating one of them to the right.
part b) Consider triangles ΔYXB and ΔYZA. In these triangles:
∠Y is common, then ∠XYB≅∠ZYA (additional information that is needed);
∠YXB≅∠YZA (given);
XY≅ZY (given).
Therefore, these two triangles have two congruent angles adjacent to congruent sides. By the ASA Postulate, ΔYXB≅ΔYZA.
ASA Postulate: If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the triangles are congruent.
Hope This Was helpful..
Answer:
You could use the ASA theorem to prove that the congruent angles and side are congruent. Or you could use CPCTC which is Corresponding parts of congruent triangles are congruent. By using these two theorems you could prove that these triangles are congruent and not similar.

Juan deposited $450 in an account that earned 7.5% simple interest.
- He did not make additional deposits and he didn't withdraw any money from the
account.
What was the balance in Juan's investment account after 3 years?
F $101.25
G $559.03
H $109.03
J $551.25
Answer:
J $551.25Step-by-step explanation:
Step one:
given data
principal= $450
rate= 7.5%= 0.075
time = 3 years.
Step two:
the simple interest formula is
A=P(1+rt)
Substituting we have
A=450(1+0.075*3)
A=450(1+0.225)
A=450(1.225)
A=551.25
The answer is $551.25

Answer:
The value of x in centimeters is 22.5 cm
Step-by-step explanation:
The corresponding sides of the similar triangles are proportion which means have equal ratios
∵ Δ ABC is similar to Δ FGH
∵ AB and FG are corresponding sides
∵ BC and GH are corresponding sides
∵ AC and FH are corresponding sides
→ That means the ratios between them are equal
∴ [tex]\frac{AB}{FG}[/tex] = [tex]\frac{BC}{GH}[/tex] = [tex]\frac{AC}{FH}[/tex]
∵ AB = 6 cm and FG = 15 cm
∵ BC = 5 cm and GH = 12.5 cm
∵ AC = 9 cm and FH = x
→ Substitute them in the rule above to find x
∴ [tex]\frac{6}{15}[/tex] = [tex]\frac{5}{12.5}[/tex] = [tex]\frac{9}{x}[/tex]
→ By using cross multiplication with the 1st and 3rd ratios
∵ 6 × x = 15 × 9
∴ 6x = 135
→ Divide both sides by 6 to find x
∵ [tex]\frac{6x}{6}[/tex] = [tex]\frac{135}{6}[/tex]
∴ x = 22.5 cm
∴ The value of x in centimeters is 22.5 cm

Answer: 2.5
[tex]\frac{p}{a}=\frac{1}{2} => a=2p\\\\\frac{a}{b}=\frac{2}{3}=> b=\frac{3}{2}a=3p\\\\\frac{b}{c}=\frac{5}{1}=>c=\frac{1}{5} b=\frac{3p}{5}\\\\\frac{c}{r}=\frac{3}{2}=>\frac{3p}{5r}=\frac{3}{2}=>\frac{p}{r}=\frac{3}{2}:\frac{3}{5}=2.5[/tex]

The sub for b is 14
Answer:
44
Step-by-step explanation:
I'm assuming you're meant to multiply so I did 3(14)+2 and it gave me 44 :)
Answer:
so it should be 44
Step-by-step explanation:
So the sub for b is 14 so substitute the b to 14
Then 3(14) they are multiplying so multiply them should equal 42
Then add the 2 the answer should be 44

A baker has 2 1/4 cups of blueberries to make three batches of muffins. How many cups of blueberries should the baker put into each batch?
Answer:
0.75
Step-by-step explanation:
To answer this question you need to divide 2 1/4 by 3. To make it easier turn 2 1/4 to 2.25 because .25 = 1/4.
