8+6/2=17-5

We can start by reducing the fraction using basic division.

Remember, numerator divided by denominator.

6 \ 2 = 3.

Rewrite the equation-

8+3=17-5

It doesn’t matter which side of the equal sign you start with, but in this case I started with the right hand.

8+3= 11

Rewrite-

11=17-5

Now subtract.


17-5=12

Write the equality.

11=12.

This is false.

11≠12.

The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.8, 15.6, 15.1, 15.2, 15.1, 15.5, 15.9, 15.5 co
julia-pushkina [17]
The confidence interval is given by the formula:
m +/- z·(σ/√n)

First, compute the mean:
m = (<span>15.8 + 15.6 + 15.1 + 15.2 + 15.1 + 15.5 + 15.9 + 15.5) / 8
    = 15.463

Then, compute the standard deviation:
</span>σ = √[∑(v - m)²/n]
   = 0.287

The z-score for a 95% confidence interval is z = 1.96.

Now you can calculate:
m + z·(σ/√n) = 15.463 + 1.96·(0.287/√8)
                        = 15.463 + 0.199
                        = 15.662

m - z·(σ/√n) = 15.463 - 1.96·(0.287/√8)
                        = 15.463 - 0.199
                        = 15.264

Therefore the confidence interval is (15.264, <span>15.662) and the correct answer is E) none of the above.</span>

geniusboy [140]

Answer:

P=1/65.

Step-by-step explanation:

We knaow that one coin in a collection of 65 has two heads. If a coin, chosen at random from the lot and then tossed, turns up heads 6 times in a row. We calculate the probability that it is the two-headed coin.

We calculate  the number of possible combinations:

C_1^{65}=\frac{65!}{1!(65-1)!}=65

Number of favorable combinations is 1.

Therefore, the probability is

P=1/65.
