The first step in the process for factoring the trinomial x2-3x - 40

Answers

Answer 1
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
Answer 2

G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.2

Answers

Answer:

[tex]P(G\ or\ H) = 0.7[/tex]

Step-by-step explanation:

Given

[tex]P(G) = 0.5[/tex]

[tex]P(H) = 0.2[/tex]

Required [Missing from the question]

[tex]P(G\ or\ H)[/tex]

Because the events are mutually exclusive, we use:

[tex]P(G\ or\ H) = P(G) + P(H)[/tex]

So, we have:

[tex]P(G\ or\ H) = 0.5 + 0.2[/tex]

$987.65 is invested at 0.4% annual interest for 5 years.
a. Simple Interest b. Compound Interest

Answers

Answer:

I. Simple interest = $19.753

II. Compound interest = $1007.6

Step-by-step explanation:

Given the following data;

Principal = $987.65

Interest rate, R = 0.4%

Time, T = 5 years

To find the simple interest;

S.I = PRT/100

S.I = (987.65*0.4*5)/100

S.I = 1975.3/100

S.I = $19.753

II. To find the compound interest;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Substituting into the formula, we have;

[tex] A = 987.65(1 + \frac{0.4}{100})^{5}[/tex]

[tex] A = 987.65(1 + 0.004)^{5} [/tex]

[tex] A = 987.65(1.004)^{5} [/tex]

[tex] A = 987.65(1.0202)[/tex]

A = $1007.6

Through extensive data collection, quality control experts have verified that the true mean weight of a wrapped Starburst candy is 5.1 grams, as advertised on the package. However, in a class activity where you selected and weighed 8 wrapped Starburst candies you obtained a p-value of 0.003 and concluded that the true mean weight of Starburst candies is not as advertised. What type of error was potentially made in this hypothesis test

Answers

Answer:

Type 1 error.

Step-by-step explanation:

H0 : μ = 5.1

H1 : μ ≠ 5.1

The Pvalue of the test = 0.003

Decision made by the researcher was conclude that mean weight is not as advertised, that is the researcher rejected the Null hypothesis.

However, when the Pvalue is < α - value , we reject the null ; The type of error the researcher could have made is that ; The mean weight may be truly as advertised, Hence, leading us to make a false positive error, thus is rejecting a true null. This is a TYPE 1 error.

In the diagram, KLMN is a rectangle, and the two shaded regions are squares. If the length of KL is 6 centimeters, and the length of KN is 14 centimeters, which is closest to the length of ST in centimeters?​

Answers

Answer:

15.2cm

Step-by-step explanation:

From the given diagram;

KN = SN = 14cm

KL = NT = 6cm

Required

ST

Using the Pythagoras theorem;

ST² = SN² + NT²

ST² = 14² + 6²

ST² = 196 + 36

ST² = 232

ST = √232

ST = 15.2cm

Hence the length of ST is 15.2cm

2. [5pts] The Pew Research Group conducted a poll in which they asked, "Are you in favor of, or opposed to, executing persons as a general policy when the crime committed while under the age of 18?" Of the 580 Catholics surveyed, 180 indicated they favored capital punishment; of the 600 seculars surveyed, 238 favored capital punishment. Is there a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18? Use the ???? = 0.01 level of significance. Show all work.

Answers

Answer:

See below for answers and explanations

Step-by-step explanation:

Here, we are comparing two proportions of a large sample size. Therefore, conducting a 2-proportion z-test is appropriate. Conditions are already assumed, so we can conduct the test.

We are testing our null and alternate hypotheses which are:

H: p1=p2 (there is no difference)

Ha: p1≠p2 (there is a difference)

Given:

x1=180

n1=580

x2=238

n2=600

p1=180/580=0.31

p2=238/600=0.4

p=(180+238)/(580+600)=418/1180=0.35

Use the formula to calculate the z-statistic:

[tex]Z=\frac{p_1-p_2}{\sqrt{p(1-p)(\frac{1}{n_1}+\frac{1}{n_2})}}[/tex]

[tex]Z=\frac{0.31-0.4}{\sqrt{0.35(1-0.35)(\frac{1}{580}+\frac{1}{600})}}[/tex]

[tex]Z=-3.24[/tex]

Calculate p-value (note that this is two-sided):

1) normalcdf(-1e99,-3.24)=5.977105194*10^-4

2) Since this is a two-sided test, we double it to get p=0.001195421

Conclusion: Since 0.0012<0.05, we reject the null hypothesis and conclude that there is a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18 because our p-value is extremely low.

Za and Zb are
complementary angles. Za measures 59º.
What is the measure of Zb?

Answers

Complementary angles are two angles whose sum adds up to 90 degrees
Za + Zb = 90
You know Za measures 59
59 + Zb = 90

Solution: Zb is 31 degrees

Answer:

Zb = 31

Step-by-step explanation:

Complementary angles mean that the angles add up to 90 so:

Za + Zb = 90

59 + Zb = 90

Zb = 90 - 59

Zb = 31

X+4y=8 and 3x+4y=0 find the slope-intercept form

Answers

Answer:

Step-by-step explanation:

Slope intercept form: y =mx + c

1) x + 4y = 8

        4y = -x + 8

Divide the equation by 4

  [tex]\frac{4y}{4}=\frac{-x}{4}+\frac{8}{4}\\\\y = \frac{-1}{4}x + 2[/tex]

Here, m = -1/4  and y-intercept = 2

2) 3x + 4y = 0

          4y = -3x

Divide the equation by 4

           y = [tex]\frac{-3}{4}x[/tex]
