(d) HA : µ > µ0, n = 28, T = 2.13

Answers

Answer 1

Using the t-distribution, it is found that the null hypothesis is rejected for a, b, c

Item a:

We have a right-tailed test, as it is being tested if the mean is more than a value.

The p-value is found using a t-distribution calculator, with 11 - 1 = 10 df and t = 1.91, hence it is of 0.0426.

The p-value is of 0.0426, which is less than 0.05, thus the null hypothesis is rejected.

Item b:

We have a left-tailed test, as it is being tested if the mean is less than a value.

The p-value is found using a t-distribution calculator, with 17 - 1 = 16 df and t = -3.45, hence it is of 0.0016.

The p-value is of 0.0016, which is less than 0.05, thus the null hypothesis is rejected.

Item c:

We have a two-tailed test, as it is being tested if the mean is different than a value.

The p-value is found using a t-distribution calculator, with 7 - 1 = 6 df and t = 0.83, hence it is of 0.4383.

The p-value is of 0.4383, which is more than 0.05, thus the null hypothesis is not rejected.

Item d:

We have a right-tailed test, as it is being tested if the mean is more than a value.

The p-value is found using a t-distribution calculator, with 28 - 1 = 27 df and t = 1.91, hence it is of 0.0195.

The p-value is of 0.0195, which is less than 0.05, thus the null hypothesis is rejected.

Therefore, in an independent random sample is selected from an approximately normal population with an unknown standard deviation. Using the t-distribution, it is found that the null hypothesis is rejected for a, b, c

Macaroni penguins weigh 5 1/2 kg when they are adults when they are born they weigh 150 g. In grams how much weight do they gain from check to adult?

Answers

Using the conversion factor we know that the penguin gained 5,350 grams of weight from a chick to an adult.

What is the conversion factor?

A conversion factor is a quantity or formula required to change a measurement from one system of units to another system of the same measurement.

The amount is often expressed as a fraction or ratio with a multiplication factor.

A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).

So, we know that:

1 kg = 100 g

Weight of the adult penguin: 5 1/2 kg that is,

5 1/2 = 10+1/2 = 11/2 = 5.5

5.5kg = 5500 g

Weight of the newborn penguin: 150 g

Weight gain from chick to adult:

5500 - 150

5,350 g

Therefore, using the conversion factor we know that the penguin gained 5,350 grams of weight from a chick to an adult.

3.y-(-8)= -6(x - 5)
4.y+8 6(x - 5)

Answers

Answer:

option 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 6x + 10 ← is in slope- intercept form

with slope m = 6

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{6}[/tex]

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - [tex]\frac{1}{6}[/tex] and (a, b ) = (5, - 8 ) , then

y - (- 8) = - [tex]\frac{1}{6}[/tex] (x - 5 ) , that is

y + 8 = - [tex]\frac{1}{6}[/tex] (x - 5) ← equation of perpendicular line

Kim wants to determine a 99 percent confidence interval for the true proportion pp of high school students in the area who attend their home basketball games. Out of n randomly selected students she finds that that exactly half attend their home basketball games.

Here we need to find  how large would n have to be to get a margin of error less than 0.01 for p.

Let us assume the worst case of the point estimate of 99% and n refers size of sample

Here the margin of error is calculated as,

=> Margin of error = z1 - α * standard error of worst case point estimate

=>  z x 99% x √(0.5(1-0.5)/n)

=> 1.96 * 0.5/√n

Now, we have to equate to given margin of error of 0.03, then

=> 0.03 = 1.96*0.5/√n

Then we have to solve for n

=> n = (1.96*0.5/0.03)²

=> n = 32.67²

=>  n = 1067.11

When we round off it, then  we get,

7t=          -7t

0 =-16t² + 23t

0=-2t(8t +11.5)

0=-2t               0 =8t-11.5

0=t                   11.5/8 =8t/t

t = 11.5/8

t = 1.437 sec

Therefore the time is 1.437 sec.

a model airplane takes off at a constant rate of 7 feet per second.

At the same time, a ball is launched from ground level with an initial velocity of 30 feet per second. The height of the ball, in feet, after t seconds is given by h=-16t^2+30x Will the airplane and ball collide. Find the time it takes for the plane collision to occur .

Suppose that the functions r and s are defined for all real numbers x as follows.
r(x)=x+5
s(x) = 4x+2
Write the expressions for (r*s) (x) and (r-s) (x) and evaluate (r+s)(1).

Answers

The values of the expression (1)  (r*s)(x) is 4x²+22x+10 (2) (r-s)(x) is -3x +3 (3) (r+s)(1) is 5x +7

How to determine the values of the expressions?

The given parameters that will help us to calculate the values are

r(x) = x+5

s(x) = 4x +2

(1)  r*s(x) will be

(x+5)(4x+2)

Opening the brackets we have

4x²+2x+20x+10

= 4x²+22x+10

(2) (r-5)(x)

Putting the values of r and s

(x+5)- (4x+2)

Open the brackets to have

x+5-4x-2

Collecting like terms to get

-3x+3

(3) (r+s)(x)

By substitution we have

x+5+4x+2

⇒5x +7

In conclusion the values of the expressions are (1)  (r*s)(x) is 4x²+22x+10 (2) (r-s)(x) is -3x +3 (3) (r+s)(1) is 5x +7

On solving the provided question, we got to know that ∠ H + ∠ K = 45°.

K therefore has a 135° measure.

What is a Parallelogram?

A unique kind of quadrilateral created by parallel lines is a parallelogram. A parallelogram might have different angles between its neighboring sides, but it must have parallel opposite sides in order to be considered one. If a quadrilateral's opposite sides are parallel and congruent, it is a parallelogram. As a result, a parallelogram is a quadrilateral with both pairs of opposite sides being parallel and equal.

the K-value of the angle.

First of all, we should be aware that the sum of the adjacent angles in the parallelogram ABCD, which has the angles A, B, C, and D, is 180°.

[tex]angle A + angle B = 180\\ angle B + angle C = 180\\ angle C + angle D = 180\\ angle A + angle D = 180[/tex]

They're considered to be a linear pair.

As a result, the parallelogram HIJK, whose angle H = 45°, is what we have.

Therefore, ∠ H +∠K = 180° (linear pair),

∠ K = 180° - 45°

∠ K = 135°,

and

∠ H + ∠ K = 45°.

K therefore has a 135° measure.

The midpoint of GH is M(-6,-3). One endpoint is H (-4,4). Find the coordinates of endpoint G

Answers

The coordinates of point G are (-8, -10)

What is the midpoint of a line?

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments

The midpoint of a line segment is the point on a segment that is at the same distance or halfway between the two ending points.

midpoint(M) = (-6, -3)

H = (-4, 4)

let the coordinates of G be (p,q)

taking the x coordinates for M, G and H

-6 = p -4/2

cross multiply

p -4 = -12

p = -12 + 4

p = -8

taking y-coordinates

-3 = q +4/2

q + 4 = -6

q = -6 -4

q = -10

coordinates of G (-8, -10)

in conclusion the coordinates of G is ( -8, -10)

PLEASE HELP! I'LL MARK YOU AS THE BRAINIEST AND I'LL GIVE YOU A LOT OF POINTS!

Answers

Answer:

B) -2x+y=8

Step-by-step explanation:

First I looked at the graph and found the y-intercept and slope.

Y-intercept = 8

I found that because the point was the on the y-axis line like (0,8)

To find the slope I identified the next point. From the Y-intercept (0,8), you have to go down 8 units. Then I saw the point go left 4 units which makes it negative.

Slope = -8/4, which is also -2

Slope Intercept Equation (y=mx+b) would be: y=-2x+8

Then I compared it to the options and that's what I got.
