An independent research firm conducted a study of 100 randomly selected children who were participating in a program advertised to improve mathematics skills. The results showed no statistically significant improvement in mathematical skills, using a significance level of 0.05. The program is effective, which of the following would be an appropriate method for increasing power in this context?

a. Increase the sample size to 200 children.
b. Use a two-sided test instead of a one sided test.
c. Decrease the sample size.
d. Use alpha-0.01 instead of a-alpha.
e. Use a one sided test instead of a two-sided test.

Answers

Answer:

b) use a two-sided test instead of a one sided test.

Step-by-step explanation:

If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.

Find the slope of a line perpendicular to the equation: 3x – 2y = 6​

Answers

Answer:

3/2x

Step-by-step explanation:

m1xm2=-1
so
y=mx+c
-2y=-3x+6
2y=3x-6
y=3/2x-3

So the gradient of the perpendicular would be

m= -2/3

find the x and y

y=3/2(0)-3
=-3

(0)=3/2x-3
x=2

So
Substitute them all into
y=mx+c

-3=-2/3(2)+c
c=-5/3

So

y=-2/3x-5/3

answer quick pls!

Jose wants to plan a skate party for his younger cousin's birthday. Skate Land charges a $65 flat fee and $7.50 per person.
Skate Land uses the equation C = 7.50p + 65 (C = total cost; p = number of people ) to calculate the total cost
based on the number of people attending. Find the total cost, C, of the birthday party if Jose invites 30 friends and family
members.

Answers

Answer:

$290

Step-by-step explanation:

We can use the equation that Skate Land created to find the total cost

C = 7.50p + 65

p = people so if we have 30 people, we have to solve 7.50 x 30

C = 225 + 65

we can now add the flat fee of $65 to get the total cost for the birthday part

C = $290

hope this helps :)

Can someone help me with this plz??

Answers

Answer:

f(x) = -4x-1

f(7) = -(4)(7)-1

f(7) = -29

g(x) = 4x^2 - x

g(-4) = 4(-4)^2 - (-4)

g(-4) = 4(16) + 4

g(-4) = 64 + 4

g(-4) = 68

Lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?

Answers

Answer:

28

Step-by-step explanation:

Neat Question.

Thanks for posting.

The straign line (horizontal) makes an isosceles triangle inside the circle. So the bottom angle of the triangle is also 59 degrees. The central angle of the interior triangle is

180 - 59 - 59 = 62.

x and the 62 degree angle are complementary -- both are in the 90 degree angle triangle made by the tangent. x + 62 = 90

x = 90 - 62 = 28

Answer:

x = 28°

Step-by-step explanation:

PQ is tangent to circle O, ∠OPQ = 90°

∠QPR = 90-59 = 31°

mOP = mOR (radius)          ∠PRO = ∠OPR = 59°    (isosceles triangle)

∠PRO = ∠QPR + x°       (triangle exterior angle)

x = 59° - 31° = 28°

C. f(x) = 2x
D. f(x) = 1x1
SMIT

Answers

D is the answer hope this helps!

Option B is correct, f(x) = 2ˣ is an exponential parent function.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The exponential parent function is of the form:

f(x) = aˣ

where a is a positive constant (the base of the exponential function).

Among the given options, the exponential parent function is,

⇒  f(x) = 2ˣ,

Because it has the form of an exponential function, where the base is 2.

f(x) = x is a linear function, not an exponential function.

f(x) = |x| is an absolute value function, not an exponential function.

f(x) = x² is a quadratic function, not an exponential function.

Hence,  f(x) = 2ˣ is an exponential parent function, Option B is correct.

Frisco ISD had a student enrollment of approximately 46,000 students in 2013 and is growing at an average rate of about 6% annually. If this rate continues the enrollment growth can be modeled using the equation 46000(1.06)t = y where t represents time in years and y represents number students. How many years will pass until the population of Frisco ISD is at 100,000 students? ≈ 13.33 years ≈ 85.91 years ≈ 5.62 years ≈ 2.05 years

Answers

Answer:

≈ 13.33 years

Step-by-step explanation:

The population of Frisco ISD after t years is given by the following equation:

[tex]y(t) = 46000(1.06)^{t}[/tex]

How many years will pass until the population of Frisco ISD is at 100,000 students?

This is t for which [tex]y(t) = 100000[/tex]. So

[tex]y(t) = 46000(1.06)^{t}[/tex]

[tex]46000(1.06)^{t} = 100000[/tex]

[tex](1.06)^{t} = \frac{100000}{46000}[/tex]

[tex]\log{(1.06)^{t}} = \log{\frac{100000}{46000}}[/tex]

[tex]t\log{1.06} = \log{\frac{100000}{46000}}[/tex]

[tex]t = \frac{\log{\frac{100000}{46000}}}{\log{1.06}}[/tex]

[tex]t = 13.33[/tex]

So the answer is ≈ 13.33 years

Answers

Answer:

Step-by-step explanation:

The number of chapters read = y

Number of days spent to read = x

Slope of the line = [tex]\frac{5}{4}[/tex] ≈ 1.25

y-intercept = 2

Slope means "number of pages read per day"

For slope = 1.25 means "1.25 pages read per day"

y-intercept means "Number of pages read initially"

y-intercept = 2 means "2 pages have been already read"
