Answer:
range = 10
Step-by-step explanation:
The range is the difference between the largest and smallest values in the data set.
largest value = 12
smallest value = 2
range = 12 - 2 = 10
Answer: D. False." Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population."
Step-by-step explanation:
- A stratified sample is obtained by dividing the population into groups without overlapping called strata and then obtaining a simple random sample from each stratum.
The individuals within each stratum should be homogeneous or similar in some way.
Therefore, the given statement "When obtaining a stratified sample, the number of individuals included within each stratum must be equal." is false because within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.
Answer:
D.
Step-by-step explanation:
In direct variations, we would have:
Where <em>k</em> is some constant.
Since this is indirect variation, instead of that, we would have:
To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>
<em />
<em />
Now plug this back into the variation:
The answer is D.
Lets do this:-
A. 7 Sandwiches
18 - 7 = 11
7 × $7.75 = $54.25
7 sandwiches cost $54.25.
11 × $4.50 = $49.50
11 soups costs $49.50
49.50 + 54.25 = 103.75
A is not d answer cuz d total of d lunches came to $113.50.
B. 8 sandwiches
18 - 8 = 10
8 × $7.75 = $62
8 sandwiches cost $62.
10 × $4.50 = 45
8 soups costs $45
62 + 45 = 107
B is not d answer cuz d total of d lunches came to $113.50.
C. 9 Sandwiches.
18 - 9 = 9
9 × $7.75 = 69.75
9 sandwiches cost $69.
9 × $4.50 = 40.50
9 soups costs $40.50
69 + 40.50 = 109.5
C is not d answer cuz d total of d lunches came to $113.50.
D. 10 Sandwiches
18 - 10 = 8
10 × $7.75 = $77.75
10 sandwiches cost $77.75.
8 × $4.50 = $36
8 soups costs $36.
77.75 + 36 = <span>113.75
</span>D is not d answer cuz d total of d lunches came to $113.50.
So, based on your answer choices there is no correct choice. <span />
H(10) is the altitude of a hot air balloon overtime after 10 minutes. In order to find h(10)'s value, you just have to substitute 10 as t in the equation. h(10) and h(t) represents the value of y in a linear equation. So pretty much: h(10)= 210 - 15(10). If calculated correctly, h(10)=60.
