Given the side lengths, determine whether the triangle is acute, obtuse, right, or not a triangle: 8,15,23
Answer:
hablas español? O no??, no se tu pregunta pique no se ingles perdón
Answer:
Obtuse angled triangle
Step-by-step explanation:
If a, b and c are the sides of a triangle with c the largest side
• If a² + b² = c² ⇒ right triangle
• If a² + b² > c² ⇒ acute angled
• If a² + b² < c² ⇒ obtuse angled
Here a = 8, b = 15, c = 23
a² + b² = 8² + 15² = 64 + 225 = 289
c² = 23² = 529
Since a² + b² < c² then obtuse angled triangle
A large bacterium measures 750 micrometers in diameter. One micrometer = 10 − 6 meters. How would you express the diameter of the bacterium in meters using scientific notation? A. 7 . 5 × 10 − 8 B. 750 × 10 − 6 C. 75 × 10 − 5 D. 7 . 5 × 10 − 4
Answer:
7.5 * 10^-4
Step-by-step explanation:
To express this, we will have to multiply 750 by the conversion unit
we have this as;
750 * 10^-6
750 = 7.5 * 10^2
so we have;
7.5 * 10^2 * 10^-6
= 7.5 * 10^(-6+2)
= 7.5 * 10^-4
The diameter of the bacterium in meters using scientific notation is 7.50 × 10^-4
Length of the bacterium = 750 micrometersOne micrometer = 10^-6How to write scientific notationMove the decimal point in between the first and second numberCount the number of digits after the decimal pointDiameter of the bacterium in scientific notation = 7.50 × 10²
Recall one micrometer = 10^-6
So
7.50 × 10² × 10^-6
= 7.50 × 10^(2-6)
= 7.50 × 10^-4

A. -4 + 8p = 68
B. 4 + 8p = 68
C. 4 + -8p = 68
D. 4 + 8p = -68
Answer:
a. -4 + 8p = 68
8p = 68 + 4 = 72
p = 72/8 = 9
a. is not the answer as the solution is not 8

Answer:
y=63, x=20, x=47, b=70, c=89, x=133
Step-by-step explanation:
1) y=63- alternate angles are the same
2) 4x+5x=180
9x=180
x=20
3) x=47
4) b=70- angles on a line equal to 180
c=89- angles in a triangle add up to 180
5) x=133- angles that are alternate are the same

Which function has the same range as
f(x)= -2sqrt (x-3)+8
Answer:
Answer: : g(x)=-sqrt(x+3)+8
Step-by-step explanation:
The function has the same range is the third one:
g(x)=-sqrt(x+3)+8
The range of this function is:
x+3>=0
sqrt(x+3)>=sqrt(0)
sqrt(x+3)>=0
Multiplying the equation by -1:
-1[ sqrt(x+3)>=0]
- sqrt(x+3)<=0
Adding 8 both sides of the equation:
- sqrt(x+3)+8<=0+8
- sqrt(x+3)+8<=8
g(x)<=8
Then Range g(x)= (-Infinite, 8]
Answer: Third option: g(x)=-sqrt(x+3)+8

50 PTS!!!!Which statements must be true to model a data set using a normal distribution?
The population mean must be greater than the sample mean.
The sample size, n, must be at least 30.
The standard deviation of the population must be less than 30.
The sample must be randomly selected.
The sample mean must equal the population mean.
-There are multiple answers
Answer:
Normal distributions are symmetric around their mean. The mean, median, and mode of a normal distribution are equal. The area under the normal curve is equal to 1.0. Normal distributions are denser in the center and less dense in the tails.
Step-by-step explanation:
Extra Answered question:
How do you determine if a distribution is normal?
Answer: In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.
I hope this is what your looking for :)
Answer:
I don't the right answers but I know these answers are incorrect:
The sample mean must equal the population mean.
The standard deviation of the population must be less than 30.

in the figure below, <1 measures (3x+20) and <2 measures x. what is the measure of <4?
Answer:
D. 140
Step-by-step explanation:
∠ 1 + ∠ 2 = 180
So:
(3x + 20) + x = 180
4x + 20 = 180
4x = 180 - 20
4x = 160
x = 160 / 4
x = 40
∠ 1 = ∠ 4
∠ 2 = ∠ 3
If ∠ 1 is equal to ∠ 4, just plug in for x and solve.
3x + 20 = 3(40) + 20 = 120 + 20 = 140
