Answer:
25 winners
Step-by-step explanation:
Determine if the side lengths given form a triangle. Justify your response. 4ft, 8ft, 12ft
Answer:
No, the sum of the two smaller sides must be greater than the longer side.
In this case this would be just a straight line.
[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]
The given lengths won't form a triangle. The sum of the 2 smaller sides should be greater (not equal too) than the longest side.
so, the longest side her is 12ft
so the smaller sides are 4ft, and 8ft.
the sum of this two sides is 12ft which same as longest side (not greater)...
so it won't form a triangle, here it will just form points on lines.

Find the exact value of x
Answer:
5
Step-by-step explanation:
what is the formula for varience
Answer:
S^2 = sample variance
x_i = the value of the one observation
\bar{x} = the mean value of all observations
n = the number of observations
Step-by-step explanation:
In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. In other words, it measures how far a set of numbers is spread out from their average value.

if f(x)=3x^2-2x+1 find f(-2)
Answer:
17
Step-by-step explanation:
3(-2)^2 - 2(-2) + 1
12 - 2(-2) + 1
12 + 5
17
Answer:
f(-2) = 3(-2)² - 2(-2) + 1 = 17
Step-by-step explanation:
f(x) = 3x² - 2x + 1
f(-2) = 3(-2)² - 2(-2) + 1
= 3 × 4 + 4 + 1
= 12 + 5
f(-2) = 17
Thus, f(-2) = 3(-2)² - 2(-2) + 1 = 17

Hi there!
[tex]\large\boxed{cos(\frac{\theta}{2} )= \frac{3}{\sqrt{7}}}[/tex]
[tex]\large\boxed{tan(\frac{\theta}{2}) = \frac{\sqrt{5}}{3}}[/tex]
Begin by recalling that:
sin(θ) = O/H, so:
Opposite side = 3√5
Hypotenuse = 7
We can solve for the adjacent sign using the Pythagorean Theorem:
7² = (3√5)² + b²
49 = 45 + b²
b² = 4
b = 2.
Thus, cosθ = 2/ 7
Use the half angle identity to solve for cos(θ/2):
cos(θ/2) = √(1 + cosθ)
Plug in the value of cosθ:
= √(1 + 2/7) = √9/7, or 3 /√7
Thus:
[tex]cos(\frac{\theta}{2}) = \frac{3}{\sqrt{7}}[/tex]
Calculate tan(θ/2) using the same process but with a different formula:
tan(θ/2) = √(1 - cosθ / 1 + cosθ)
Substitute in the value of cosθ:
tan(θ/2) = √(1 - 2/7)/(1 + 2/7)
= √(5/7)/(9/7) = √5/9 = √5/3

Find the area and perimeter of the following figure.
Answer:
AREA: 49.2 miles
PERIMETER: 49.2
Step-by-step explanation:
in finding the area, multiply by 4 the same because it has the same sizes, A=s⁴ or Side x side x side x side
In finding the Perimeter
you need to add 12.3 miles to four sizes or same sizes
P= 12.3 + 12.3 + 12.3 + 12.3

A cross section is the intersection of a
✓ and a
Answer: three dimensional figure and plane.
Step-by-step explanation:
A cross section is the intersection between a (three dimensional figure) and also a (plane).
When an object is being cut straight, the shape that we get is referred to as the cross section. We should note that several parallel cross sections will be firmed when we cut a particular object into slices.
A large firm that owns a chain of grocery stores wanted to see if they could increase the average number of patrons who visit by implementing a rewards member program. To test this, they randomly chose half of their 60 locations and started the rewards program only at those locations, while the other half of locations did not receive the rewards program. They also collected information the amount of money spent on these extra customers. Which of these answers represents an element of randomization in this study?
a. use a computer program to select the locations have a rewards program and those that don't
b. have an unbiased person just pick half of the stores to have the rewards program
c. allow store managers to volunteer
Answer:
a. use a computer program to select the locations have a rewards program and those that don't.
Step-by-step explanation:
Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.
A large firm that has a chain of the grocery stores has implemented a reward member program to increase the visits of patrons. In order to check this, they test the same at 60 different locations.
They do this by collecting information about the money spent and the number of customers Hence they use a computerized program that allows for asking reward programs and checks those who are eligible for the rewards. The store manager of the chain store has placed such as system in place. This system is simple as it tracks those who have not yet got the rewards by checking their information.Hence the option is A is correct.

If the answer is not integer, enter it as a fraction in the simplest from
- 3/2 • 8/6 divided by (- 2/15)
Answer:
15
Step-by-step explanation:
1) multiply numerator x numerator and denominator x denominator
- 24/12
2) simplify the fraction
-24 : 12 = -2
12 : 12 = 1
-2/1 = -2
3) inverte the therms of -2/15 and change the sign of operation from : to x
- 2 x (-15/2)
4) multiply the numerators remembering that minus x minus = +
30/2
5) simplify the fraction
30 : 2 = 15

The Student Monitor surveys 1200 undergraduates from 100 colleges semiannually to understand trends among college students. Recently, the Student Monitor reported that the average amount of time spent per week on the Internet was 19.0 hours. You suspect that this amount is far too small for your campus and plan a survey. You feel that a reasonable estimate of the standard deviation is 10.0 hours. What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence
Answer:
A sample size of 385 is needed.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
You feel that a reasonable estimate of the standard deviation is 10.0 hours.
This means that [tex]\sigma = 10[/tex]
What sample size is needed so that the expected margin of error of your estimate is not larger than one hour for 95% confidence?
A sample size of n is needed. n is found when M = 1. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1 = 1.96\frac{10}{\sqrt{n}}[/tex]
[tex]\sqrt{n} = 1.96*10[/tex]
[tex](\sqrt{n})^2 = (1.96*10)^2[/tex]
[tex]n = 384.16[/tex]
Rounding up:
A sample size of 385 is needed.

Answer:
x = 4
y = 4√3
tan 60° = 1.7321
Step-by-step explanation:
sin 30 = 4/8
0.5 = x/8
x = 4
y² = 8² - 4² = 64 - 16 = 48
y = √48 = 4√3
tan 60° = (4√3)/4 = √3 = 1.7321
