If k=-2, what is the value of 5 - (2k-1)?

Answer:

0.0882

Step-by-step explanation:

Given that:

Mean(m) = 281

Standard deviation (s) = 33

Probability of weight between 291 and 299 gram

Obtain the standardized score (Zscore):

P (X ≤ 291)

Zscore = (x - m) / s

Zscore = (291 - 281) / 33

Zscore = 10 / 33 = 0.303

P(Z ≤ 0.303) = 0.61906 (Z probability calculator)

P (X ≤ 299)

Zscore = (x - m) / s

Zscore = (299 - 281) / 33

Zscore = 18 / 33 = 0.5454

P(Z ≤ 0.5454) = 0.70726 (Z probability calculator)

Hence, probability of weight between 291 and 299 gram = 0.70726 - 0.61906 = 0.0882

Answer:

5.4 :))

Step-by-step explanation:

ok so first you take 2*1.4=2.8 (you replace the Y with the number)

so now you have 2.8+2.6 which is equal to 5.4

Answer:

5.4

Step-by-step explanation:

2*1.4 is 2.8. Now the expression is y2+2.6=. Now, that we figured out what 2y is, which is 2.8, we need to add on 2.6. 2.6 + 2.8 is equal to 5.4. Now, to write out the whole equation, it would look like this.

2y+2.6=?

y2+2.6=?

2.8+2.6=?

5.4

So in the end:

2y+(2.6)= 5.4

Answer:

35 Notebooks

Step-by-step explanation:

$1.50x35=52.5

$52.5+$40=$92.5

or $92.50 - 40=$52.5

35x1.5=52.5

Answer:

35 notebooks

Step-by-step explanation:

let notebook as be 'x'

here, $40.00+x($1.50)=$92.50

x($1.50)=$92.50-$40.00

x($1.50)=$52.50

x=$52.50/$1.50

x=35

Answer:

c. The particle is moving away from the origin at a decreasing speed.

Step-by-step explanation:

Since x(2) which represents the particles position is less than zero, that is, x(2) < 0, it shows that the particle is at the left of the origin at t = 2.

Also, x'(2) which represents the particle's speed at t = 2 is less than zero, that is, x(2) < 0, the particles speed is negative at t = 2.

Finally, since x"(2) which represents the particle's acceleration at t = 2 is less than zero, that is, x"(2) < 0, the particle's acceleration is negative at t = 2 and thus decreasing.

So, combining these three conditions together shows that the particle is moving away from the origin at a decreasing speed at time, t = 2.

Since [tex]x(2)[/tex], which represents the subatomic particle location, is below zero, that is, [tex]x(2) <0[/tex], it indicates that the particles are to the left of the origin at [tex]t = 2.[/tex]

Therefore, the answer is "Option C".

Answer:

c  . Response Bias

Step-by-step explanation:

This is a convenience sampling and it could lead us to a response bias. Those parents who bring their children to play in the park would most likely to support rebuilding the park while the parents those who do not bring their children would not be sampled and thus would not be included in the sampling. This sample method involved is not representative of the entire population. So it is a responsive bias.

I hope this helps you out! :D

Answer:

A and E

Step-by-step explanation:

I have attached the graph of the problem.

Answer:

the first one is 5/12 and the second one is 6/28. Hope this helps and have a nice day:)

Answer: 5/12, 3/14

Step-by-step explanation:

first problem:

first, we just reduce the numbers.

5/4 x 1/3

then, we simply multiply.

5/12

second problem:

again, we just reduce the numbers.

3/2 x 1/7

and then multiply.

3/14

Answer:

2 m/s

Step-by-step explanation:

Given the graph of the baseball thrown into air.

John throws the baseball into the air from a given height and then the baseball reaches a maximum height and then comes back to ground.

The height of the baseball (in metres) is modeled by the function graph with respect to time.

To find:

The average rate of change of height of the ball from the point the ball is thrown to the maximum height.

Solution:

Here, the average rate of change can be found by dividing the distance between the two points with the change in time.

The starting time is 0 seconds.

The starting height is 3 metres.

The ending time is 2 seconds i.e. at which the ball reaches the maximum height.

The height is 7 metres.

Therefore, the average rate of change is:

[tex]\dfrac{\text{Change in height}}{\text{Change in time}}\\\Rightarrow \dfrac{7-3}{2-0}\\\Rightarrow \dfrac{4}{2}\\\Rightarrow 2\ m/s[/tex]

Answer:

2 meters per second
