Answer:

408 bags of dog food

Step-by-step explanation:

The question asks for the total bags of dog food. Because they give you two existing values expressing how much dog food of each type there is, all you must do is add them together. 145 + 263 = 408

if 5 litres of water are drawn from a cylindrical container of internal diameter 56cm find the drop in the level of water in the

AlexFokin [52]

Answer:

the drop in the level of water in the container is 2.03 cm

Step-by-step explanation:

The volume of a cylinder can be written as;

$V = \pi r^2h=\frac{\pi d^2h}{4} \\where;\\r = radius \\h = height \\d = diameter$

the change in height when the volume changes can be derived by differentiating the equation.

$dV =\frac{\pi d^2}{4} dh\\dh = dV\frac{4}{\pi d^2}$

substituting the given values;

$\left \{ {{dV=5 litres= 5000cm^3} \atop {d=56 cm}} \right.$

$dh = 5000\frac{4}{\pi * 56^2}\\dh = 2.03cm$

the drop in the level of water in the container is 2.03 cm

Suppose that 24% of the students in the first group answered yes and that 73% of the students in the second group answered yes.

Lera25 [3.4K]

Answer:

Price Discrimination OR Law of Demand; according to the complete question.

Step-by-step explanation:

24% of the students in the first group answered yes.

73% of the students in the second group answered yes.

More students in the second group were willing to pay $75 for the pair of jeans BECAUSE they were told that the normal price was much higher.

From this information, I guess that the first group was told (by the jeans vendor probably) that the $75 was higher than the normal price of the jeans. This will be the reason why a lesser percentage of students in Group A are willing to purchase the pair of jeans.

This is an example of PRICE DISCRIMINATION effect on decision making. Price discrimination is used in product marketing.

The same pair of jeans in Situation A cost higher than the normal price while in Situation B it cost lower than the normal price. Even though the figure given is static at $75 in both cases, the data that follows in the question tells it as 2 different prices; one favourable to the buyers and another not so favourable to the buyers.

The LAW OF DEMAND also applies here. The higher the price, the lesser the quantity demanded (by a group of students) and the lower the price, the higher the quantity demanded.

Here is a linear equation in two variables: 2x+4y−31=123. Solve the equation, first for x and then for y.

Allushta [10]

Answer:

$x = 77 - 2y$

$y = \frac{77 - x}{2}$

Step-by-step explanation:

Given

$2x + 4y - 31 = 123$

Required

Solve for x and for y

$2x + 4y - 31 = 123$

Add 31 to both sides

$2x + 4y - 31+31 = 123+31$

$2x + 4y = 154$

Solving for x

Subtract 4y from both sides

$2x + 4y - 4y = 154 - 4y$

$2x = 154 - 4y$

Divide by 2

$x = 77 - 2y$

Solving for y

$2x + 4y = 154$

Subtract 2x from both sides

$2x - 2x + 4y = 154 - 2x$

$4y = 154 - 2x$

Divide by 4

$y = \frac{154 - 2x}{4}$

Split

$y = \frac{77 - x}{2}$

The mean of a population being sampled is 64, and and the standard deviation is 6. If the sample size is 50, the standard error

Fiesta28 [93]

Given:
mean = 64
standard deviation = 6
sample size = 50

Standard error of the sample mean = standard deviation / √sample size

Standard error = 6 / √50 = 6/7.07 = 0.85
