Answer:

  (x +3)(x +1)(x -2)

Step-by-step explanation:

A graphing calculator is a good tool for finding factors fast. Each zero (p) gives rise to a factor (x -p).

The graph shows zeros at -3, -1, and 2, so your factorization is ...

A class was conducting a series of probability experiments.
Which set of events would have an equally like chance of occurring?
A
spinning a spinner with 3 sections and tossing a coin.
B
rolling a six-sided cube and drawing 6 marbles out of a bag.
С
tossing a coin and choosing an odd number between 1 and 7
D
drawing 1 card out of 25 cards and choosing a letter out of the alphabet.

Answers

I believe the answer would be B, since both situations give you 6 chances at drawing/rolling the right number/marble.

Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.

Option B is correct.

Probability:

Probability of series of experiments shown below;

A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .

 When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]

So that, set A has not equally like chance of occurring.

B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]

   When one marble is drawn out of 6 marble in a bag, then  probability is [tex]\frac{1}{6}[/tex]

Therefore, set B has equally like chance of occurring.

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride? ​

Answers

Answer:

8

Step-by-step explanation:

You can solve this by creating a linear equation.

Slope: 2.50

Y-intercept: 4.70

y=2.50x+4.70

Since we know that the total fare was 24.70 we can plug it into the y.

24.70=2.50x+4.70

Now solve for the equation.

20=2.50x

8=x

So he went 8 miles with the taxi.

Total number or mile taxi run is 8 miles.

Given that;

Pick up charge = $4.7

Charges per mile = $2.5 per mile

Total fare = $24.7

Find:

Number of mile taxi ride

Computation:

Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]

24.7 = 4.7 + [Total number or mile taxi run][2.5]

[Total number or mile taxi run][2.5] = 24.7 - 4.7

[Total number or mile taxi run][2.5] = 20

Total number or mile taxi run = 20 / 2.5

Total number or mile taxi run = 8 miles

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?

Answers

Answer:

42

Step-by-step explanation:

the ratio 2:4 can be reduced to 1:2,

where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.

If there are 14 girls, then there must be 28 boys (14 x 2 = 28).

Now to get the total number we need to add the total number of boys and girls together.

So 14 + 28 = 42

Hope it helps :)

Answer:

32

Step-by-step explanation:

14 + 28 = 32

2 x 7 = 14

4 x 7 = 28

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value

Answers

Answer:

x = 16°

Step-by-step explanation:

We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°

∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)

∠ACD = x, ∠DCE = 148,  ∠ECD = x

substituting the respected values for the angles gives:

x + 148 + x = 180

2x + 148 = 180

subtracting 148 from both sides:

2x + 148 - 148 = 180 - 148

2x = 32

Dividing both sides by 2, to get x:

2x/2 = 32/2

x = 16°
