If a triangle has a right angle and a 30 degree angle, what is the measure of the third angle?
Answer:
60
Step-by-step explanation:
All triangles have a total measurement of 180 degrees. So to find the last angle measure subtract 90 and 30 from 180, 180-(90+30). This equals 60 degrees. Additionally, a triangle with a 90 and 30 degree angle is known as a 30-60-90 special right triangle. All of these triangles will have 60 as their third measurement.
Which equation has the same solution as x^2 - 8x - 15 =3
Answer:
x^2 - 6x -18 is the same so you can write
x^2 - 6x -18 = ( x^2 - 8x - 15 = 3)
Step-by-step explanation:
When we subtract 3 each side we get -18 as -15 -3 is -18
x^2 - 6x -15 = 3
x^2 - 6x -15- 3 =
x^2 - 6x - 18 = 0
When equations equal or set equal to zero we can then use the quadratic formula found in your book.
x1
= −(−8) − √ (−8)2 − 4×1×(−18) / 2×1
= 8 − 2 × √ 34
/2
≈ −1.831
x^2
= −(−8) + √ (−8)2 − 4×1×(−18)
/2×1
= 8 + 2 × √ 34 / 2
≈ 9.831

QUESTION
Which shape of distribution would typically have the smallest standard deviation?
normal distribution
uniform distribution
skewed left distribution
skewed right distribution
Answer:
The shape that has the smallest standard deviation is;
Uniform distribution
Step-by-step explanation:
A uniform distribution is a probability distribution where the outcomes are equally likely such as the probability of landing any face of a die, or the probability of landing a head or a tail, or a perfect random number distribution
Therefore, the outcome of a uniform distribution are all the same and the standard deviation is zero (0)
Therefore, the uniform distribution has the smallest standard deviation.

The first year of a charity walk event had an attendance of 500. The attendance
y increases by 5% each year.
How many people will attend in the 10th year?
A) 525 People
B) 814 People
C) 250 People
Answer:
b
Step-by-step explanation:
Number of people in the 10th year can be determined using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future number of people at the charity
P = number of people at the charity in the first year
R = rate of increase
N = number of years
500 x (1.05)^10 = 814 people

What is the POINT in this equation y+5= 9/4 (x+25) *
Answer:
The vertex (your "point") is (-25, -5).
Step-by-step explanation:
Compare the given equation to
y - k = m(x - h). We see that the slope, m, is 9/4; the x-coordinate of the vertex is h = -25, and the y-coordinate of the vertex is k = -5.
The vertex (your "point") is (-25, -5).

A function is shown below.
g(x) = 19.60 + 1.74x
What is the value of g (30) ?
Answer:
g(30) = 71.8
Step-by-step explanation:
g(x) = 19.60 + 1.74x
g(30) = 19.60 + 1.74 (30)
g(30) = 19.60 + 52.20
g(30) = 71.8
The value of g(30) is 71.8
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation.
The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
g(x) = 19.60 + 1.74x
Now, We have to find g(30) we have to put x= 30 in the function
g(30) = 19.60 + 1.74(30)
g(30) = 19.60 + 52.2
g(30) = 71.8
Hence, the value of g(30) is 71.8

The speed of sound (shockwave) in an explosion is 100mph. How many seconds does the shockwave reach 2km away?
Answer:
t = 44.73 s
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 100 mph = 44.704 m/s
We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m
We know that,
Speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s[/tex]
So, it will take 44.73 seconds to reach 2 km.

A classmate buys and resells scooters. If they original buy a scooter for $45.85 and mark it up 90%. What is the new selling price?
Answer:
$87.12
Step-by-step explanation:
To mark up the price you are basically doing 45.85×190%.
If you take a percentage and make it a normal number you need to divide by 100.
190÷100= 1.9
So you multiply 45.85×1.9=87.115
Because this is money you cant have $87 and 11 and a half cents. So you need to round
You need to round up because it is 5, which means that you get $87.12

The formula for the area of the shaded region on the diagram is: Area of the circle - Area of the square The area of the circle is 76.8 cm2 rounded to 1 decimal place. The area of the square is 12.7 cm2 truncated to 1 decimal place. Write the error interval for the area, a , of the shaded region in the form m < a < n .
The error interval for the area is 64.2< a < 63.93
What is error interval?Error intervals are the limits of accuracy when a number has been rounded or truncated. They are the range of possible values that a number could have been before it was rounded or truncated.
Given:
Area of circle = 76.9 cm²
Area of square = 12.7 cm²
Now, 1 decimal point
Area of circle,
= 76.9+0.05 and = 76.9-0.05
= 76.95 and = 76.85
Area of square,
= 12.7-0.05 and = 12.7+-0.05
=12.65 and = 12.75
Area of shaded region in the form m < a < n .
m= 76.95-12.75
m= 64.2
n= 76.85-12.65
n= 63.93
Area of shaded region is 64.2< a < 63.93.
