if a coin is tossed 4 times, the odds of it coming up either heads every time or tails every time are 1:7.What is the probabilit
ivanzaharov [21]

Answer:

1

Explanation:

From the question, we have it that the probability of heads coming up every time or tail coming up every time is 1:7 if the coin is tossed in 4 tosses

What this means is that we have a probability of 1/8 of head showing up and a probability of 7/8 that a tail will show up in each toss of the coin

For four throws, it means all four are heads or all four are tails

If all four are heads, we have the probability of this happening as:

\text{ (}\frac{1}{8})^{}

if all four are tails, we have the probability as:

\frac{7}{8}

Now, the probability of either heads or all tails after 4 tosses will be:

\text{ }\frac{1}{8}\text{ + }\frac{7}{8}\text{ = 1}

Help please! math assignment
MArishka [77]

Answer:

The left side   5

The bottom  10

The slanted side  11

Step-by-step explanation:

To find the perimeter of the triangle, add up the side lengths

x+ 2x+1 + x+5 = 26

Combine like terms

4x+6 = 26

Subtract 6

4x+6-6 =26-6

4x=20

Divide by 4

4x/4 = 20/4

x=4

The left side  x = 5

The bottom  x+5    = 5+5 = 10

The slanted side  = 2x+1 = 2*1 +1 = 10+1 =11

Linear Function Table
Andrej [43]

a. The difference between two outputs that are 1 unit apart.

You need to Use y2 - y1 / x2 - x1 to find the difference

I will choose x2 as 1 and x1 as 0

(29 - 21) / (1 - 0)

8/1 so The difference is 8 per 1 unit.

b. Use the same formula

I will choose -3 as x2 and -5 as x1

(5 - (-11)) / (-3 - (-5))

(5 + 11) / (-3 + 5)

16 / 2 so the difference is 16 per 2 units.

c. I will choose 2 as x2 and -1 as x1

(45 - 21) / (2 - (-1))

24/3 so the difference is 24 per 3 units.

d. The ratios of the differences to the input intervals reduced all equal each-other, which is 8 per 1 unit.
