Answer:

x² + 2x - 15 = 0

x² + 2x + 1 = 16

(x + 1)² = 16

You can then go forward with that to solve it:

x + 1 = √16

x = -1 ± √16

x = -1 ± 4

x = 3, -5

160 adult tickets were sold

Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.

Set up equations to represent the problem.

Let the A and S represent the number of adult and student ticket respectively. So we can write:

12A + 6S = 3,240 --- (1)

A + S = 380  --- (2)

From (2):

S = 380 - A ---- (3)

Put (3) in (1):

12A + 6S = 3,240

12A + 6 (380 - A) = 3,240

12A + 2280 -6A = 3,240

6A = 3,240 - 2280

6A = 960

A = 960/6

A = 160 tickets

Thus, the number of adult ticket sold is 160

Answer:

0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.

Step-by-step explanation:

When the distribution is normal, we use 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.

In this question, we have that:

[tex]\mu = 450, \sigma = 60[/tex]

Find the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.

This is the pvalue of Z when X = 312. So

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

[tex]Z = \frac{312 - 450}{60}[/tex]

[tex]Z = -2.3[/tex]

[tex]Z = -2.3[/tex] has a pvalue of 0.0107

0.0107 = 1.07% the probability that a randomly selected boy in secondary school can run the mile in less than 312 seconds.

Four points are always coplanar if they: lie in same plane.

Firstly understanding the coplanar points. Coplanar points are refers to the points if they are present in same plane. Further defining the word "plane". Plane is the surface, which is flat and two dimensional in nature. The surface is infinite. Plane can also be referred as the analogue of 3 dimensional space, you we can also interpret the plane as extension of point or line.

So, the points that lie on different planes will not be coplanar. Now, understanding the points on lines. Two or more lines may or may not be in same plane. Subsequently, points may or may not be coplanar, depending upon the lines they are placed on. Thus, we can not definitely say that points lying on the same line are coplanar.

Answer:

B.) |w - 5.76| / 36 = 0.03

Step-by-step explanation:

Given :

Weight of individual candy piece = 0.16 ounce

Number of candy pieces per package = 36

Allowable variation in weight of individual piece = 0.03 ounces

The highest and lowest allowable weight, w of a package of 36 pieces ;

Actual manufacturing weight of entire 36 candy = (36 * 0.16) = 5.76

Allowable weight ± actual weight ≤ allowable variation

w ± 0.16 ≤ 0.03

|w - 0.16| ≤ 0.03

For the entire 36 candy pieces :

|w - 0.16*36| = 0.03 * 36

|w - 5.76| = 1.08

|w - 0.16*36| = 0.03 * 36

Could also be written as :

|w - 5.76| / 36 = 0.03

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order.

If there are 2 sandwiches, 2 drinks, and 2 desserts to choose from and the lunch special is a sandwich, drink, and dessert.

The total choices are 3 in that 2 options for every choice are available.

Thus total combination can be made = 2³

total combination can be made = 8

Therefore, the total number of possible lunch specials is 8.
