X^2 < 4
A. Graph A
B. Graph B
C. Graph C
D. Graph D

Answer:

GCF of the numbers is 3 and it can be written as 3(1+5)

Step-by-step explanation:

Given the expression 3+15

First we need to find their factors

3 = 3×1

15 = 3×5

Since 3 is common to both factors, hence the GCF is 3

Factorize

3+15

= (3×1)+(3×5)

Factoring 3 out

= 3(1+5)

Hence the GCF of the numbers is 3 and it can be written as 3(1+5)

Answer:

s = c + 15

s + c = 27

substitute for s:

(c + 15) + c = 27

2c = 12

c = 6

s = 21

The system of equation which correctly represents the situation is s + c = 27 and s - c = 15.

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Given that,

Combined total of sheep and cows = 27

Number of sheep = Number of cows + 15

Let s represents the number of sheep and c represents the number of cows.

s + c = 27

s = c + 15 ⇒ s - c = 15

Hence the system of equation is s + c = 27 and s - c = 15.

Answer: 333.33km

Step-by-step explanation:

Average speed is calculated as:

= Distance / Time

Since Alex takes 30 minutes to travel 50 km in her car, Alex average speed will be:

= 50km / 30minutes

= 50km / 0.5hour

= 100km/hour

Since Alex drives at an average speed that is 2/5 of the average speed that Roy's train travels. Roy's average speed will be:

= 100 ÷ 2/5

= 100 × 5/2

= 250km/hour

Since Roy travels for 1 hour and 20 minutes on his train, his distance travelled will be:

= Speed × Time

= 250 × 1 hour 20 minutes

= 250 × 1 20/60

= 250 × 1 1/3

= 250 × 4/3

= 1000/3

= 333.33km

Roy travels 333.33km

Answer:

26

Step-by-step explanation:

since the question asks for a value of k where the point (5, 0) is part of a solution, plug 5 into the x value and 0 into the y value:

4x-y<=k-6

4(5)-0<=k-6

20-0<=k-6

20<=k-6

26<=k

In this case, k can be equal to any number that is greater than or equal to 26 for the point (5, 0) to be a solution, but the question asks for the minimum value of k, meaning the smallest value. since the question asks for the smallest value, the answer we're looking for is 26.

Answer:

1/9

Step-by-step explanation:

Probability  =  Expected outcome/Total outcome

From the given pi chart,

Total outcome = 360degrees (since the total angle in a circle is 360 degrees)

Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;

Expected outcome = 40degrees

Pr(scoring a 5) = 40/360

Pr(scoring a 5) = 1/9

Hence the probability of scoring a 5 is 1/9

Answer:

1/9

Step-by-step explanation:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Divide the number of events by the number of possible outcomes.

B Jenna asked some randomly selected students whether they preferred dogs, cats, or other pets. ... part-time job. The results are shown in the two-way frequency table below. ... Two hundred students were asked about their favorite sport.

Step-by-step explanation:

A two-way table is a useful way to organize data that can be categorized by two variables. Suppose the school board asked 125 households if they would support a tax ...

Soccer - Male; 19 Female; 31

Basketball - Male; 21 Female; 29

Total - Male; 40 Female; 60

A two-way or contingency table is a statistical table that shows the observed number or frequency for two variables, the rows indicating one category and the columns indicating the other category.

Given, one hundred people were asked about their favorite sport.

Since the Total number of humans is 50

And female who likes  Soccer is 31

Thus, Male who likes Soccer = 50 - 31 = 19

Since the Total number of humans is 50

And female who likes  Basketball is 29

Thus, Male who likes Basketball = 50 - 29 = 21

So,

Total males = 21 + 19 = 40

Total number of female = 29 + 31 = 60

False More males were surveyed than females. (since total male-to-female ratio is 2/3)

True More females like soccer.

True An equal number of people like soccer and basketball.

False Twice as many females as males like basketball.

Step-by-step explanation:

Jai rolls a standard six-sided die, numbered from 1 to 6. Which word or phrase describes the probability that he will roll a number between 1 and 6 (including 1 and 6)?

There are 6 possible outcomes for rolling a die numbered from 1 to 6: {1, 2, 3, 4, 5, 6}.

Within that set of outcomes, there are 6 possible ways of rolling a number between 1 and 6 (including 1 and 6): {1, 2, 3, 4, 5, 6}.

6 out of 6 is 1. When something will occur all the time, we say it is certain.

Answer:

r = 3.75

Step-by-step explanation:

Using Pythagoras' identity in the right triangle ABC

AC² = BC² + AB²

(r + 6)² = r² + 9²

r² + 12r + 36 = r² + 81 ( subtract r² from both sides )

12r + 36 = 81 ( subtract 36 from both sides )

12r = 45 ( divide both sides by 12 )

r = 3.75
