Two of the three interior angles are known. Both are equal to 55°. This can be seen by looking closely at the picture. To find the third angle subtract the other two from 360°
[tex]360\textdegree-55\textdegree-55\textdegree=x[/tex]
b)
Do the same thing only afterward subtract the third angle from 180 to find the supplementary angle
[tex]360\textdegree-40\textdegree-28\textdegree=ans\textdegree\\180\textdegree-ans\textdegree=x[/tex]

A 12-sided solid has equal-sized faces numbered 1-12
a. Find P(number greater than 10).
b.Find P(number less than 5)
c. If the 12-sided solid is rolled 200 times, how many times would you expect either a 4, 6, or 9 to be rolled?
Answers
Answer:
a) [tex]P(x > 2) = \frac{1}{6}[/tex]
b) [tex]P(x < 5) = \frac{1}{3}[/tex]
c) 50 times
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12\}[/tex]
Solving (a): P(x > 10)
First, list all outcomes of x
[tex]x = \{11,12\}[/tex] --- 2 outcomes
So, the probability is:
[tex]P(x > 2) = \frac{2}{12}[/tex]
Simplify
[tex]P(x > 2) = \frac{1}{6}[/tex]
Solving (b): P(x < 5)
First, list all outcomes of x
[tex]x = \{1,2,3,4\}[/tex] --- 4 outcomes
So, the probability is:
[tex]P(x < 5) = \frac{4}{12}[/tex]
Simplify
[tex]P(x < 5) = \frac{1}{3}[/tex]
Solving (c): Expected outcome of 4, 6 or 9 in a roll of 200
We have:
[tex]n = 200[/tex]
First, list all outcomes of x
[tex]x = \{4,6,9\}[/tex] --- 3 outcomes
So, the probability is:
[tex]P(x ) = \frac{3}{12}[/tex]
Simplify
[tex]P(x ) = \frac{1}{4}[/tex]
The expected number of rolls (E(x)) is calculated as:
[tex]E(x) = P(x) * n[/tex]
[tex]E(x) = \frac{1}{4} * 200[/tex]
[tex]E(x) = 50[/tex]

what are sides 'a' and 'b' called in a right triangle
Answers
Answer:
The relation between the sides and angles of a right triangle is the basis for trigonometry.
Step-by-step explanation:
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).
Answer:
The legs
Step-by-step explanation:
In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

A baker has three different recipes. Recipe A uses 3 cups of flour to make 12 rolls. Recipe B uses 5 cups of flour to make 24 rolls. Recipe C uses 11 cups of flour to make 48 rolls. Which recipe uses the most cups of flour per roll?
a) Recipe A
b) Recipe B
c) Recipe C
d) The ratios are all proportional
Answers
Answer:
Recipe A
Step-by-step explanation:
Hope this helped!!!
Answer:
[tex]{\huge\red{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]
Recipe A:Cups of flour used = 3
Rolls made = 12
Cups of flour per roll
[tex] = \frac{3}{12} \\ = \frac{1}{4} \\ = 0.25[/tex]
Recipe B:Cups of flour used = 5
Rolls made = 24
Cups of flour per roll
[tex] \frac{5}{24} \\ = 0.20[/tex]
Recipe C:Cups of flour used = 11
Rolls made = 48
Cups of flour per roll
[tex] \frac{11}{48} \\ = 0.22[/tex]
Now compare Recipe A, B & C.[tex]0.25 > 0.22 > 0.20[/tex]
Recipe A > Recipe C > Recipe B.
✏ So, Recipe A used the most cups of flour per roll (option a).

It is desired to estimate the average weight of a new born baby. The birth records of arandom sample of 60 babies' weights showed a mean of 7.0 lbs and standard deviation of 1.5 lbs.Construct a 95% confidence interval forμ.
Answers
Answer:
95% confidence interval for the mean
(6.61251, 7.38749)
Step-by-step explanation:
Step:-1
Given that a random sample 'n' = 60
Given that mean of the sample x⁻ = 7.0
Given that the standard deviation of the sample (S) = 1.5
Level of significance = 0.05
Degrees of freedom = n-1 = 60-1 = 59
t₍₀.₀₅ , ₙ₋₁₎ = 2.0010
Step(ii):-
95% confidence interval for the mean is determined by
[tex](x^{-} - t_{0.05,n-1} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.05 , n-1} \frac{S.D}{\sqrt{n} } )[/tex]
[tex]( 7.0 - 2.0010 \frac{1.5}{\sqrt{60} } , 7.0 + 2.0010 \frac{1.5}{\sqrt{60} } )[/tex]
(7.0 - 0.38749 , 7.0 + 0.38749)
(6.61251 , 7.38749)
Final answer:-
95% confidence interval for the mean
(6.61251 , 7.38749)

At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?
Answers
Answer:
6/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750

x=29.44
y=48.08
z=68
Step-by-step explanation:
opp/adj = tan(30)
17/x = tan(30)
x = 29.44
hyp^2 = x^2+y^2
hyp^2 = (29.44)^2 + (17)^2
hyp^2 = 867 + 289
hyp = 34
opp/hyp = Sin(45)
34/y = Sin(45)
y = 48.08
adj/hyp = Cos(45)
z/(48.08) = Cos(45)
z = 68

Answers
Answer:
a) 58.24 square centimeters
b) 5cm
Step-by-step explanation:
a) Area of a parallelogram
The formula for the Area of a parallelogram = Base × Height
Height : 5.2cm
Base : 11.2cm
Area = 5.2 cm × 11.2cm
= 58.24 square centimeters
b) Volume of a cuboid
The formula for the Volume of a cuboid = Length × Width × Height
7cm = Width
3cm = Length
y = Height
Volume = 105cm³
We are to find y
Hence,
105cm³ = 7cm × 3cm × y
y = 105cm³/7cm × 3cm
y = 5cm
