Factor the following quadratic function:
-
y = 7x2
- 48x - 7
How do I do it
Answer:
(7x + 1)(x - 7).
Step-by-step explanation:
y = 7x^2 - 48x - 7
Use the 'ac' method:
7 * 7 = 49
Now we need 2 numbers whose product is 49 and whose sum is the 'middle' number -48.
They are -49 and 1,
Now we write the function as:
7x^2 - 49x + 1x - 7
= 7x((x - 7) + 1(x - 7) (x - 7) is common so we have
(7x + 1)(x - 7).

Answer:
13/24
can't be simplified
Step-by-step explanation:
you can make them have the same denominator by multiplying.
denominator of 24 is 8*3
and 3*8
then multiply their numerators by the same values
7/8 times 3= 21/24
1/3 times 8= 8/24
subtract
21-8= 13
so 13/24

Is the product of 12 and 3 4 more or less than 12? Explain your answer in complete sentences.
Answer:
Either way, whether that's 3 and 4, 3, 4, or 34, the product will still be bigger than 12.
Step-by-step explanation:
The only thing that would lessen 12 would be if it were multiplied by a negative number.

Step-by-step explanation:
A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 432 gram setting. It is believed that the machine is underfilling the bags. A 24 bag sample had a mean of 426 grams with a variance of 225. A level of significance of 0.01 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
The decision rule will be as follows: Reject the null hypothesis if test-statistic < -2.5 or fail to reject the
Now, Our test-statistic was -1.96, which is greater than -2.5. Thus, we will fail to reject the null hypothesis.
Step-by-step explanation:
We are given;
Population mean; μ = 432
Sample mean; x¯ = 426
Sample size; n = 24
Variance; Var = 225
Now, standard deviation from variance is; σ = √Var
Thus, σ = √225
σ = 15
Hypothesis is defined as;
Null hypothesis; H0: μ ≥ 432
Alternative hypothesis: Ha: μ < 432
Formula for the test statistic since sample size is less than 30 is;
t = (x¯ - μ)/(σ/√n)
Plugging in the relevant values;
t = (426 - 432)/(15/√24)
t = -1.96
Now,we are given significance level of 0.01; our DF = n - 1 = 24 - 1 = 23.
From t-table attached, we can see that at DF of 23 and significance value of 0.01, the critical value is 2.5
However, this is a left tailed test as the rejection region is to the left.
Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.5.
The decision rule will be as follows: Reject the null hypothesis if test-statistic < -2.5 or fail to reject the
Now, Our test-statistic was -1.96, which is greater than -2.5. Thus, we will fail to reject the null hypothesis.
