Answer and Step-by-step explanation:
The signs didn't really "swap". Instead, the whole function was divided by -1, or we could say the function was divided by -3. That would turn:
-18x² - 15x + 3 = 0
into
(-18 / -3)x² - (15 / -3)x + (3 / -3) = 0
6x² + 5x - 1 = 0
And that gives the "swapped signs".
Answer: 11 servings
Step-by-step explanation:
To get the number of servings, all we need to do is divide 8 1/4 by 3/4
converting 8 1/4 to improper fraction will yield 33/4
8 1/4 ÷ 3/4
=33/4 ÷ 3/4
= 33/4 ÷ 4/3
The 4 at the numerator will cancel the 4 at the denominator. we will be left with;
=33/3 =11
Therefore, there will be 11 servings.
Answer:
The value of test statistic is 1.338
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 16.000
Sample mean, 
= 16.218
Sample size, n = 22
Alpha, α = 0.05
Sample standard deviation, s = 0.764
First, we design the null and the alternate hypothesis
We use one-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Thus, the value of test statistic is 1.338
i believe the formula you need is; SA= n(3/10 ib) + 9b
<span>7x + 2y = 48
</span><span>7x + 2(3) = 48
7x + 6 = 48
7x = 42
x = 6
answer </span><span>when y = 3, x = 6</span>
