if you know the area and the base of a triangle, explain how you can find the height.
Answer:
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
Step-by-step explanation:
A restaurant did a survey among 100 customers to find their food preferences. The customers were asked about their preferences for chocolate cake or cheesecake. Out of the total 50 people who liked chocolate cake, 15 also liked cheesecake. There were 25 people who liked cheesecake.
Part A: Summarize the data by writing the values that the letters A to I in the table below represent.
Like chocolate cake Do not like chocolate cake Total
Like cheesecake A D G
Do not like cheesecake B E H
Total C F I
Part B: What percentage of the survey respondents did not like either chocolate cake or cheesecake?
Part C: Do the survey results reveal a greater dislike for chocolate cake or cheesecake? Justify your answer.
The values for the first part is..25 like choc...25 do not like choc..25 for the 3rd and yes..25 for 4th
Part b...zero percent..every 1 liked on or the other
Part c..it's equal for like choc..and same like cheese..

Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2
Enter the opposite of 4/5 and negitive 7/15
Answer:
-4/5 and 7/15
Step-by-step explanation:
the opposite of a number is a number that is equal length from 0 on a number line. So the opposite of 4/5 is -4/5 and the opposite of -7/15 is 7/15

In a unit circle, 0 = 360°. What is the terminal point?
Answer:
The terminal point would be (1,0)
Step-by-step explanation:
Recall that in a unit circle, x° is located at the point (cosx°,sinx°) therefore the terminal point would be (cos(360°),sin(360°)) -> (1,0)
In a unit circle, it is given that 0 = 360°. The terminal point would be equal to (1,0).
what is the terminal point?The circle unit terminal Points in the unit circle to locate the terminal point, begin with (1,0).
In a unit circle, x° is located at the point (cosx°,sinx°)
In a unit circle, 0 = 360°.
therefore the terminal point would be
(cos(360°),sin(360°)) -> (1,0)

1.An appliance store sells major appliances (such as dishwashers, washing machines, dryers); for an additional fee, the store offers an extended service contract beyond the warranty period. The owner of this appliance store notes that she sold 145 dishwashers during the past 6 months; 45% of these customers also purchased the extended service contract. To maintain customer relations, the owner likes to contact her customers to see how they are enjoying their new appliances. She conducts a random sample of 35 of these customers. a)What is the probability that fewer than 40% of the customers in the sample purchased the service contract
Answer:
0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
45% of these customers also purchased the extended service contract.
This means that [tex]p = 0.45[/tex]
Sample of 35
This means that [tex]n = 35[/tex]
Mean and standard deviation:
[tex]\mu = 0.45[/tex]
[tex]s = \sqrt{\frac{0.45*0.55}{35}} = 0.0841[/tex]
What is the probability that fewer than 40% of the customers in the sample purchased the service contract?
This is the p-value of Z when X = 0.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.4 - 0.45}{0.0841}[/tex]
[tex]Z = -0.59[/tex]
[tex]Z = -0.59[/tex] has a p-value of 0.2776
0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.
