Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

Conditional Probability:

$P(A|B)=\dfrac{P(A \cap B)}{P(B)}$

From the spinner shown, there are 10 sections.

$P(< 6)=6/10\\P(Yellow)=3/10$

$P($Yellow and $$

Therefore:

$P(< 6 | \text{Yellow})=\dfrac{P($

Answer:

The solution is (-2/3,7/3)

Step-by-step explanation:

1) What is the bottom part saying? I will just solve what I see on top since that may be the only part you need to solve, comment what the bottom part is if you need it, I'll help.

2) y=7/3 by solving. for y.

3) x = -4/6 by solving for x after plugging in the y.

4) Your answer is (-2/3,7/3).

How can you write (x-3)(x+4)-18 as a product of two binomials? Please show work please help

ANEK [815]

Answer:

OPTION C: (x - 5)(x + 6)

Step-by-step explanation:

Given: (x - 3)(x + 4) - 18

Product of (x - 3) and (x + 4) = x² + 4x - 3x - 12

Therefore, (x - 3)(x + 4) - 18 = x² + x - 30

This is a quadratic equation and the roots are x = 5, -6.

This can be written as binomials as:

(x - 5)(x + 6) which is the required answer.

So, OPTION C is the answer.

The data shown represent the number of runs made each year during Bill Mazeroski’s career. Check for normality.

const2013 [10]

Answer:

The given data is not normal.

Step-by-step explanation:

We are given the following data:

30, 59, 69, 50, 58, 71, 55, 43, 3, 66, 52, 56, 62, 36, 13, 29, 17, 31

Condition for normality:

Mean = Mode = Median

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{800}{18} = 44.44$

Mode is the most frequent observation of the data.

Since all the value appeared once, there is no mode.

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Sorted data: 3, 13, 17, 29, 30, 31, 36, 43, 50, 52, 55, 56, 58, 59, 62, 66, 69, 71

Median =

$=\dfrac{9^{th}+10^{th}}{2} = \dfrac{50+52}{2}=51$

Since the mean, mode and median of data are not equal, the data is not normal.
