The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Let x be the number of cheese squares that she eats and y is the number of turkey slices that she eats. If nina can eat 12 or more grams of protein, hence:
2x + 3y ≥ 12
The inequality that represents the possible ways nina can eat 12 or more grams of protein is 2x + 3y ≥ 12

K/11 = 7
multiply 11 to both sides
K/11 (11) = 7(11)
multiply 7 and eleven together
K = 7(11)
Answer
K = 77
77 is your answer
hope this helps
The answer would be 135 (B)
Answer:
a
The null hypothesis is

The Alternative hypothesis is

b

c

d
Yes the mean population is significantly less than 21.
Step-by-step explanation:
From the question we are given
a set of data
20 18 17 22 18
The confidence level is 90%
The sample size is n = 5
Generally the mean of the sample is mathematically evaluated as


The standard deviation is evaluated as



Now the confidence level is given as 90 % hence the level of significance can be evaluated as

%

Now the null hypothesis is

the Alternative hypothesis is

The standard error of mean is mathematically evaluated as

substituting values


The test statistic is evaluated as

substituting values


The critical value of the level of significance is obtained from the critical value table for z values as

Looking at the obtained value we see that
is greater than the test statistics value so the null hypothesis is rejected
