Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Old design samples(n1) = 220

New design samples (n2) = 220

P1 = 81/220 = 0.368 ; P2 = 41/220 = 0.186

Null hypothesis : p1 - p2 ≥ 0.05

Alternative hypothesis : p1 - p2 < 0.05

Using the test statistic formula :

t = (P1 - P2) / √[P(1-P)(1/n1 + 1/n2)]

P = (81 + 41)/(220 + 220) = 122/440 = 0.277

1 - P = 0.723

t = (0.368 - 0.186) / (√(0.277(0.723)(1/220 + 1/220)))

t = 4.265

P value from z test at α = 0.05

P value = 0.00002

Test for significance at α = 0.01 ;

Test for significance at α = 0.1

Result is significant at both α levels, hence reject the Null.

Step-by-step explanation:

C) Isabelle has 5 fewer pieces of candy than Destiny.

c represents the pieces of candy Destiny has, and c - 5 represents the pieces of candy Isabelle has.

Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.

The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:

[tex]P(X < 4.5) = \frac{4.5 - 0}{15 - 0} = 0.3[/tex]

Answer:

1/8 hours

Step-by-step explanation:

First, we have to make our 2 fractions denominators the same to be able to subtract them! We want both of our denominators to be 8 so 5/8 already had 8 so we just need to change 1/2 to do that we are going to multiply the fraction by 4 so 1 x 4 = 4/2 x 4 = 8. Now we have 5/8 and 4/8. All we need to do now is subtract our fractions! 5/8 - 4/8 = 1/8

Answer:

Step-by-step explanation:

First, because it is a quadratic function, we know that its graph is a parabola that opens up, as x is positive. Because x has no coefficients, we also know that it is a basic parabola, with no vertical stretches or compressions, and a vertex at x=0. Because of the -3, we know the parabola has a verticle shift down 3 units, making the parabola's vertex at (0,3). Hope this helps!

Answer:

Leia is incorrect; 10 should not be in the domain.

Step-by-step explanation:

the domain is x, the range is y. The domain really should be '1, 4, 7, 13, 16 ,19' and the 10 should not be there.

Step-by-step explanation: To solve this absolute value inequality,

our goal is to get the absolute value by itself on one side of the inequality.

So start by adding 2 to both sides and we have 4|x + 5| ≤ 12.

Now divide both sides by 3 and we have |x + 5| ≤ 3.

Now the the absolute value is isolated, we can split this up.

The first inequality will look exactly like the one

we have right now except for the absolute value.

For the second one, we flip the sign and change the 3 to a negative.

So we have x + 5 ≤ 3 or x + 5 ≥ -3.

Solving each inequality from here, we have x ≤ -2 or x ≥ -8.

Answer:

Step-by-step explanation:

since 90 hundredths is 90/100, 90 hundredths is a fraction.  if you divide 90 by 100 you get 0.90  

since 7 thousandths is 7/1000 divide that as a fraction also.

You will get 0.007

add them together 0.907
