Answer:

(Assuming the circle isn't a zero)

2x + 2y =4

Step-by-step explanation:

For there to be infinite solutions, it should be the same line.

If you divide 2x + 2y = 4 by 2 on both sides you get the original equation

(line A), which is x + y = 2

Alex and Leandro purchase two matinee movie tickets. A matinee ticket costs , a drink costs , and a bag of popcorn costs . Defin

REY [17]

Answer: (2p + 1.5d) + (5*(2)) = T

Step-by-step explanation: (2p + 1.5d) + (5*(2)) = T

Since there are no costs, i'll make up my own uwu;

Matinee = $5

Popcorn = $2

Drink = $1.5

T = total

(2p + 1.5d) + (5*(2)) = T

2p ($2 for each bag of popcorn - p represents popcorn)

1.5d ($1.5 for each drink, - d represents drinks)

5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.

Identifying Possible Triangles

Masja [62]

Answer:

3rd triangle can be constructed with dimensions 2,6,7.

Step-by-step explanation:

sum of any two sides > third side.

difference of any two sides < third side

8+5=13 not >14 (no triangle.)

7+8=15 not >15 (no triangle)

2+6=8>7

2+7=9>6

7+6=13>2

7-2=5<6

7-6=1<2

6-2=4<7

so it is a triangle.

6+3=9 not >10 (not a triangle)

Consider a value to be significantly low if its z score less than or equal to minus−2 or consider a value to be significantly hi

den301095 [7]

Answer:

Test scores of 10.2 or lower are significantly low.

Test scores of 31 or higher are significantly high

Step-by-step explanation:

Z-score:

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

$Z = \frac{X - \mu}{\sigma}$

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 problem, we have that:

$\mu = 20.6, \sigma = 5.2$
