Answer:

Last one:

The probability of the spinner not landing on A and rolling a prime number is 1/3

Step-by-step explanation:

The probability of the spinner not landing on A: 2/3

Prime outcomes on a dice:

2, 3, 5

The probability of rolling a prime number: 3/6 = 1/2

The probability of the spinner not landing on A and rolling a prime number is:

2/3 × 1/2

1/3

Answer:

Last one:

The probability of the spinner not landing on A and rolling a prime number is 1/3

Step-by-step explanation:

The probability of the spinner not landing on A: 2/3

Prime outcomes on a dice:

2, 3, 5

The probability of rolling a prime number: 3/6 = 1/2

The probability of the spinner not landing on A and rolling a prime number is:

2/3 × 1/2

1/3

If M is the set of all square of integers that are less than 100 and N is the set of all positive odd numbers that are under 15,
ollegr [7]

A set is simply the group of numbers.

  • <em>The set of M and N are: </em>M = \{1,4,9,16,25,36,49,64,81\}<em>  and </em>N= \{1,3,5,7,9,11,13\}<em>.</em>
  • <em>The set of M n N is: </em>M\ n\ N = \{1,9\}<em>.</em>
  • <em>The set of  M u N is: </em>M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}<em />

<u>(a) The set of M and N</u>

Given that:

M = squares of integers less than 100

N = Positive odd numbers less than 15

So, we have:

M = \{1,4,9,16,25,36,49,64,81\}

N= \{1,3,5,7,9,11,13\}

<u>(b) M n N and M u N</u>

M n N is the set of common elements between sets M and N.

So, we have:

M\ n\ N = \{1,9\}

M u N is the set of all elements in sets M and N.

So, we have:

M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}

. Write an equation that is perpendicular to y=2x – 1 and has y-intercept of -3
blagie [28]

The answer is very simple .

First you need to determine the slope, which is the reciprocal of the first line.

Then,

y = mx + b

m => -1/m

The perperdicular line has a new slope equal to m = -1/2

In the formula (y - y1) = m ( x - x1 ) + b , you should sustitude this value.

So the final equation will be

-3 = -1/2 (0) + b

b = - 3

y = (-1/2)x - 3

That is the solution

An experiment is conducted to test the claim that james bond can taste the difference between a martini that is shaken and one t
sammy [17]

In hypothesis testing the claim that we have to test always goes into alternative hypothesis. The null hypothesis is negation of claim.

Here the claim to be tested is James bond can taste the difference between a martini that is shaken and one that is stirred.

So negation of this claim is James bond can not taste the difference between a martini that is shaken and one that is stirred.

So the null hypothesis for given experiment is

Null hypothesis: James bond can not taste the difference between a martini that is shaken and one that is stirred.

Alternative hypothesis: James bond can taste the difference between a martini that us shaken and one that is stirred.
