Answer:

  c.  20 days

Step-by-step explanation:

Divide the total available rice by the rate of its use:

  time = quantity/(rate of use)

  (15 lb)/(0.75 lb/day) = (15/0.75) days = 20 days

Answer:

The ratio of yellow jellybeans to total jellybeans is 1:6.

Step-by-step explanation:

The ratio of yellow jellybeans to total jellybeans is given by the number of yellow jellybeans divided by the number of total jellybeans.

In this question, we have that:

There are 3 yellow jellybeans.

In total, there are 8 + 3 + 5 + 2 = 18 total jellybeans.

So the ratio is:

3/18 = 1/6 = 1:6

The ratio of yellow jellybeans to total jellybeans is 1:6.

Answer:

[tex]P(Spade) = 0.25[/tex]

Step-by-step explanation:

Given.

In a deck, there are:

[tex]Cards = 52[/tex]

[tex]Spade= 13[/tex]

Required

Determine the probability that a selected card is a spade

This is represented as: P(Spade) and it is calculated using:

[tex]P(Spade) = \frac{Spade}{Cards}[/tex]

Substitute 13 for Spade and 52 for Cards

[tex]P(Spade) = \frac{13}{52}[/tex]

[tex]P(Spade) = 0.25[/tex]

Hence, the required probability is 0.25

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope.

Finding the slope of a line, given two points:

When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.

Points (4,r), (r,3)

Change in y: 3 - r

Change in x: r - 4

Slope is 0, so:

[tex]\frac{3 - r}{r - 4} = 0[/tex]

[tex]3 - r = 0[/tex]

[tex]r = 3[/tex]

The value is r = 3.

Answer:

8.625 ft for each side.

Step-by-step explanation:

This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th  is 9 (although i doubt saying 1th is right, but just because).

B, all the numbers make the inequality true:).

Step-by-step explanation:

Answer:

C . 2y-x= -6

Step-by-step explanation:

A system of linear equations can have no solution, a unique solution or infinitely many solution.

We say two linear equations has infinitely many solutions when the result is true.

To determine if a system has infinitely many solutions, the coefficient of their respective variables (x and y) would be equal. Also the constant of both equations would be equal.

Given that x - 2y = 6

The coefficient of x is 1, coefficient of y is -2 and constant is 6. The equation with the same attributes is:

C . 2y-x= -6

2y - x = -6

multiply through by -1

x - 2y = 6

It is same as the above

Adding both x - 2y = 6 and 2y-x= -6 gives 0 = 0

[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]

The reciprocal of  [tex]\frac{1}{3}[/tex] is 3, so finding the reciprocal will replace the division sign with a multiplication sign.

= [tex]\frac{1}{2}[/tex] x 3

= [tex]\frac{3}{2}[/tex] or 1[tex]\frac{1}{2}[/tex] or 1.5

Slope = change in Y over change in X:

Slope = (1 - 8) / (5-9)

Slope = -7/-4

Slope = 7/4

Answer:

The slope is [tex] \frac{7}{4} [/tex].

.

Step-by-step explanation:

Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆And now we just plug in!

[tex]m = \frac{1 - 8}{5 - 9} = \frac{ - 7}{ - 4} = \frac{7}{4} [/tex]

The standard error of the sample mean is 0.7835140.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Population mean = 62.95

Population standard deviation = 5.65

Sample size = 52

The standard error of the sample mean :

= Standard deviation / √(sample size)

= 5.65 / √(52)

= 0.7835140

Hence, the standard error is 0.7835140.
