Answer:

The school sold 130 candles

Step-by-step explanation:

Given that the plants sold for $12.50 each and the  candles sold for $3.75 each. If the  school raised raised $3,987.50 and sold 410 candles and plants altogether then the number of candles and plants sold may be computed simultaneously as follows:

Let the number of candles sold be c and the number of plants sold be p. If the school sold 410 candles and plants altogether

p + c = 410

p = 410 - c

if the plants sold for $12.50 each and the  candles sold for $3.75 each and the school raised raised $3,987.50

12.5p + 3.75c = 3,987.50

12.5(410 - c) + 3.75c = 3,987.50

5125 -12.5c +3.75c = 3,987.50

-8.75c = 3,987.50 - 5125

-8.75c = -1137.5

c = -1137.5/-8.75

= 130

Answer:

An = 32 - (4*(n-1))

Step-by-step explanation:

the starting term for this pattern is 32 (which you will need to include in the "rule")

you also know that the next term is the previous term - 4

so!

we can write this pattern as

An = 32 - (4*(n-1))

An = any number of term in the pattern

- ex). A2 = 28, A3 = 24, etc

n = the nth term

- the 3rd term = 24, the fourth term = 20, etc

Answer:

0.6892 = 68.92% of bottles are within specification.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

On average, each bottle contains 2.07 liters of soda, with a standard deviation of 0.06 liters.

This means that [tex]\mu = 2.07, \sigma = 0.06[/tex]

The plant’s quality manager wants to determine how well the process is operating.

To do this, we find the proportion of bottles within specification.

The specification limits for a bottle of soda are 2.1 liters and 1.9 liters

This is the pvalue of Z when X = 2.1 subtracted by the pvalue of Z when X = 1.9. So

X = 2.1

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{2.1 - 2.07}{0.06}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915.

X = 1.9

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.9 - 2.07}{0.06}[/tex]

[tex]Z = -2.83[/tex]

[tex]Z = -2.83[/tex] has a pvalue of 0.0023

0.6915 - 0.0023 = 0.6892

0.6892 = 68.92% of bottles are within specification.

Answer:

[tex] 128 \: {ft}^{2} [/tex]

Step-by-step explanation:

Area of the shaded region = 3 times the area of one square with side length 8 ft - 3 time the area of one triangle with base 8 ft and height 8 ft

[tex] = 3 {(8)}^{2} - \cancel 3 \times \frac{1}{\cancel 3} \times 8 \times 8 \\ \\ = 3 \times 64 - 64 \\ \\ = (3 - 1)64 \\ \\ = 2 \times 64 \\ \\ = 128 \: {ft}^{2} [/tex]

Answer:

Y = 13

Step-by-step explanation:

You can use the sine rule to solve this.  The sine rule states that:

Sin(a) / A = Sin(b) / B = Sin(c) = C

In other words the sine of the angle in any corner in a triangle, divided by the length of the opposite side, will be equal to that of the other two sides as well.  

In this case, we can take the ratio between the sine of the right angle, and each of our hypotenuses, and state them as equal, giving us the solution:

sin(90) / (5y + 13) = sin(90) / 6y

1 / (5y + 13) = 1 / 6y

5y + 13 = 6y

6y - 5y = 13

y = 13

6.23 kg of pears (check for rounding)

Step-by-step explanation:

8.3 / 4 = 2.08 kg of apples as it is 1/4 of 8.3

8.3 - 2.08 = 6.22 kg of pears

Step-by-step explanation:

Answer:

Step-by-step explanation:

We are to rank the options given in the question to correctly prove the theorem that: "If A & B are set, and A is a subset of B"

To arrange the steps in the correct order, we have:

(a) Assume that B is countable

(b) The elements of B can be listed as b1, b2, b3

(c) Since A is a subset of B, taking the subsequence of {bn} that contains the terms that are in A gives a listing of the elements of A.

(d) Therefore A is countable, contradicting the hypothesis.

(e)  Thus B is not countable

Answer:

77°

Step-by-step explanation:

As we can see ABCD is a cyclic quadrilateral so opposite angles of a cyclic quadrilateral is supplementary.

< A + <B = 180° { being opposite angles of cyclic quadrilateral }

2x + 9° + 3x + 1° = 180°

5x + 10° = 180°

5x = 180° - 10°

5x = 170°

x = 170° / 5

x = 34°

Now

< A = 2x + 9°

= 2 * 34° + 9°

= 77°

Answer:

x = 6 , y = 0   (x , y) = (6 , 0)

x = 12, y = 3   (x , y) = (12 , 3)

x = 24, y = 9   (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0    (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3   (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9   (x , y) = (24 , 9)
