A group of 80 people who had been diagnosed as prediabetic because of high blood glucose levels volunteered to participate in a

study designed to investigate the use of cinnamon to reduce blood glucose to a normal level. Of the 80 people, 40 were randomly assigned to take a cinnamon tablet each day and the other 40 were assigned to take a placebo each day. The people did not know which tablet they were taking. Their blood glucose levels were measured at the end of one month. The results showed that 14 people in the cinnamon group and 10 people in the placebo group had normal blood glucose levels. For people similar to those in the study, do the data provide convincing statistical evidence that the proportion who would be classified as normal after one month of taking cinnamon is greater than the proportion who would be classified as normal after one month of not taking cinnamon?
a. No conclusion can be made about the use of cinnamon because the people in the stuey were volunteers
b. There is convincing statistical evidence at the level of 0.01
c. There is convincing statistical evidence at the level of 0.05 but not at the ver.01

(3x+2)-(x+5)=3x+2-x-5

(3x+2)-(x+5)=2x-3

ANSWER: Linear binomial

(b)

(3x+8)+(4x^{2}-x)=3x+8+4x^{2}-x

(3x+8)+(4x^{2}-x)=4x^{2} +2x+8

ANSWER: Quadratic trinomial

(c)

(x^{2}+7x)-(x^{2}+5)=x^{2}+7x-x^{2}-5

(x^2+7x)-(x^2+5)=7x-5

ANSWER: Linear binomial

(d)

(2x+8)+(3x^2-2)=2x+8+3x^2-2

(2x+8)+(3x^2-2)=3x^2+2x+6

ANSWER: Quadratic trinomial

Kim orders catering from Midtown Dinerfor $35. She spends $5 on a large order of potato salad and the rest on turkey sandwich. E
aivan3 [116]

Answer:

Kim had bought 12 sandwiches.

Step-by-step explanation:

Given:

Amount spend at Midtown Dine = $35

Amount spend on large order of potato salad = $5

Cost of each sandwich = $2.5

We need to find the number of sandwich did Kim bought.

Solution:

Let the number of sandwich Kim bought be 'x'.

Now we know that;

Amount spend at Midtown Dine is equal to sum of Amount spend on large order of potato salad and number of sandwich Kim bought multiplied by Cost of each sandwich.

framing in equation form we get;

5+2.5x=35

Subtracting both side by 5 we get;

5+2.5x-5=35-5\\\\2.5x=30

Dividing both side by 2.5 we get;

\frac{2.5x}{2.5}=\frac{30}{2.5}\\\\x=12

Hence Kim had bought 12 sandwiches.
