Answer:
No. of blue chips contain in a bag = P = 27.5 % = 0.27
No. of chips random selected at a time with replacement = n = 5
We know that the mean and standard deviation of the sampling distribution of the sample proportion (p) is given by :-
\mu\-_pμ\-p = p
= 0.275
\sigma_pσp = \sqrt{\frac{p (1-p)}{n} }np(1−p)
Where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
= \sqrt{\frac{0.275 ( 1 - 0.275)}{5} }50.275(1−0.275)
= 0.1997
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.
What is the mean and standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.
A bag contains chips of which 27.5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement.
Then the mean is given as,
Mean = 0.275 x 5
Mean = 1.375
Then the standard deviation is given as,
Standard deviation = √[5 x 0.275 x (1 - 0.275)]
Standard deviation = √0.99687
Standard deviation = 0.9984
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.

Gerri purchases a coupon book with discounts for her favorite coffee shop. Every coupon for the coffee shop offers the same discount. The table shows her total savings, y, based on the number of coupons, x, used from the book. What are the slope and y-intercept of the line represented by the points shown in the table? slope: 2, y-intercept: –20 slope: 2, y-intercept: 10 slope: 5, y-intercept: –20 slope: 5, y-intercept: 10.
Answer: slope: 2, y-intercept: –20
Explanation:
Y-intercept is the point at which the line intersects the y axis- meaning x = 0
From the table y = -20 when x= 0
y-intercept: -20
To find the slope
m = deltaY/deltaX = -20+10/0-5 = 2

It converges the light in to one point.
What is Flashlight?A portable hand-held electric lighting is known as a flashlight (US, CA), torch (UK), or torch (AU).
The light source used to commonly be a tiny incandescent light bulb, but since the mid-2000s, light-emitting diodes (LEDs) have taken their place. The common components of a flashlight are a light source mounted in a reflector, a clear cover (often paired with a lens) to shield the light source and reflector, a battery, and a switch, all of which are housed in a case.
Around 1899, the development of dry cells and tiny incandescent electric lamps made the first battery-operated flashlights feasible. Today's flashlights run on disposable or rechargeable batteries and typically use light-emitting diodes.
Therefore, It converges the light in to one point.

How many grams of lead product would theoretically be produced between 17. 0 g potassium iodide, ki, and 25. 0 g of lead (ii) nitrate, pb(no3)2?.
The number of grams of lead product that would theoretically be produced from the given reaction is; Mass of lead product = 23.6 g
Potassium iodide reacting with Lead(II) Nitrate would yield the balanced equation;
2KI + Pb(NO₃)₂ = 2KNO₃ + PbI₂
2moles : 1 mole = 2 moles : 1 mole
From online tables;
Molar mass of KI = 166 g/mol
Molar mass of Pb(NO₃)₂ = 331.2 g/mol
We are given;
Mass of KI = 17 g
Mass of Pb(NO₃)₂ = 25 g
Thus;
Number of moles of PbI₂ yielded in order to find the limiting reactant will be;
no of moles of PbI₂ from KI = (17g/166 g/mol) × (1 mole of PbI₂/2 mol of KI)
no of moles of PbI₂ from KI = 0.0512 mols
Similarly;
no of moles of PbI₂ from Pb(NO₃)₂ = (25g/331.2 g/mol) × (1 mole of PbI₂/1 mol of Pb(NO₃)₂)
no of moles of PbI₂ from Pb(NO₃)₂ = 0.0755 moles
We can see that KI produced the least amount of moles. Thus;
Mass = 0.0512 * molar mass of PbI₂
From tables, molar mass of PbI₂ = 461 g/mol
Thus;
Mass of lead product = 461 * 0.0512
Mass of lead product = 23.6 g

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.
The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant
Given data
Mass of Player one = 105kg
Mass of Player two = 93Kg
The Velocity of Player one = 8.6m/s
The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)
Applying Newton’s Second Law in Terms of Momentum because the mass is not constant
When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,
We also want to assume that the players stuck together after the collision
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.
P = M1V1 + M2V2
P= 105*8.6+93*9.0
P = 903 +837
P = 1740 kg · m/s.

The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.
The true statement about the graph of f(x) is [tex]f(x) = \frac 35x + 3[/tex]
The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).
Start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{3-0}{0--5}[/tex]
Simplify
[tex]m = \frac{3}{5}[/tex]
The equation of the line is then calculated as:
[tex]y = m(x -x_1) + y_1[/tex]
This gives
[tex]y = \frac 35(x -0) + 3[/tex]
Open bracket
[tex]y = \frac 35x + 3[/tex]
Express y as a function of x
[tex]f(x) = \frac 35x + 3[/tex]
Hence, the true statement about the graph of f(x) is [tex]f(x) = \frac 35x + 3[/tex]

What factors would have the least effect on a region’s climate?.
Answer:
Longitude and Population Density
Explanation:
Longitude
Longitude won't have much effect because it is just across the earth in E to W. (east to west). While, Latitude will affect the Earth because there is something called a Equator, which is USUALLY hot, and the Polar zones, which are mostly Cold.
Population Density
Population Density won't affect much because the amount of carbon dioxide a person produces is pretty less. But yeah, the factories make a lot of more Carbon Dioxide so that is why they will be producing more than the people. But people can't produce so much to warm up their environment.
