Suppose tossing a coin 8 times represents the 8 cups of tea, heads represents a correct identification of what was poured first,

tea or milk, and tails represents an incorrect identification of what was poured first. Select the best conclusion you would draw about whether the woman was just guessing.
A. Repeat the process many times (1000). If 6 correct out of 8 cups rarely occurs, then it is most likely that the woman was just guessing as to what was poured first.
B. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.
C. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is likely that the woman was just guessing as to what was poured first.
D. Repeat the process many times (1000). If 4 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.

Answer:

A. Repeat the process many times (1000). If 6 correct out of 8 cups rarely occurs, then it is most likely that the woman was just guessing as to what was poured first.

Step-by-step explanation:

Since tossing a coin 8 times implies 8 cups of tea, with the given conditions.

The sample space = 1000

Then;

             \frac{6}{8} × 1000 = 750

If 6 correct out of 8 cups occurs (750 out of 1000), the woman got 750 correctly. Thus it can be inferred that it is likely that she knew what was poured first, either the tea or milk.

But, if 6 correct out of 8 cups rarely occurs (i.e 250 out of 1000), then it is most likely that the woman was just guessing as to what was poured first.

Match each equation to an equivalent equation written in slope-intercept form.
choli [55]

Answer:

  In order down the left side, ...

  • y = 1/3x +2
  • y = 1/2x +3
  • y = 2x +6
  • y = -2x +3

Step-by-step explanation:

To put a linear equation in slope-intercept form, you solve for y, then simplify.

<u>x -3y = -6</u>

Subtract x and divide by -3:

  y = 1/3x +2

__

<u>2y -6 = x</u>

Add 6 and divide by 2:

  y = 1/2x +3

__

<u>-x +(1/2)y = 3</u>

Add x and multiply by 2:

  y = 2x +6

__

<u>2x +y = 3</u>

Subtract 2x:

  y = -2x +3

_____

<em>Comment on the algebra</em>

Note that when we say add, subtract, multiply, or divide by something or other, we mean to <em>do that to both sides of the equation</em>. That is required by the properties of equality.

If you remember the rule: do the same thing to both sides of the equation, then algebra suddenly becomes much easier.

Suppose the ages of multiple birth (3 or more babies) are normally distributed with a mean age of 31.7 years and a standard devi
artcher [175]

Answer:

The percent of these mothers are between the ages 30-35 is 36.53%

Step-by-step explanation:

we are given

mean of age =31.7 years

\mu=31.7

standard deviation of 5.2 years

\sigma=5.2

For age=30 years:

x=30

we can find z-score

z=\frac{x-\mu}{\sigma}

we can plug values

z=\frac{30-31.7}{5.2}

z=-0.32692

For age=35 years:

x=35

we can find z-score

z=\frac{x-\mu}{\sigma}

we can plug values

z=\frac{35-31.7}{5.2}

z=0.63462

now, we can use normal distribution table

P(-0.32692

now, we can find percentage

=0.3653\times 100

=36.53%
