Answer:
[tex]\frac{5}{16}[/tex]
Step-by-step explanation:
1) Find the total number of marbles
5 blue + 6 red + 3 black + 2 yellow
= 16 marbles
2) To find the probability of selecting a blue marble, divide the number of blue marbles by the number of total marbles:
5 blue marbles ÷16 marbles
[tex]= \frac{5}{16}[/tex]
Therefore, the probability of selecting a blue marble is [tex]\frac{5}{16}[/tex].

A researcher believes that there is a difference in how cautious male stray cats and female stray cats are when approaching people. He knows that the stray cat population is 50% male and 50% female. In order to test this hypothesis, he visits 15 different areas where stray cats live and records the gender of the first cat to approach him. He finds that 11 of the 15 cats that approach him are male. Using a sign test and an alpha of .05: A) What is the null hypothesis
Answer:
The null hypothesis is that there is no difference in the mean number of male and female cats
H₀; μ₂ - μ₁ = 0
Step-by-step explanation:
The given parameters are;
The given percentage of male stray cat population = 50%
The given percentage of female stray cat population = 50%
The number of areas the researcher visits, n = 15
The number of stray male cats he finds = 11
The kind of test to be performed = Sign test
The significance level, α = 0.05
A) Therefore the null hypothesis is H₀; μ₂ - μ₁ = 0
The alternative hypothesis is Hₐ; μ₂ - μ₁ ≠ 0.

Step-by-step explanation:
So, Start with the formula
V= pi ×R² × H
V= pi × 9² × 2
V= pi × 81 × 2
V = 162 pi in³
Then ×2 = 342 in³
required volume =162π or 508.94or 509in³
Answer:
solution given:
radius (r)=9in
height(h)=2 in
we have
volume [V]=πr²h=π×9²×2=162π or 508.94in³

Solve x2−5x=8 by completing the square. Round your answers to the nearest hundredth.
Answer:
[tex] x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2} [/tex]
Step-by-step explanation:
[tex] x^2 - 5x = 8 [/tex]
[tex] x^2 - 5x + \dfrac{25}{4} = 8 + \dfrac{25}{4} [/tex]
[tex] (x - \dfrac{5}{2})^2 = \dfrac{57}{4} [/tex]
[tex] x - \dfrac{5}{2} = \pm \sqrt{\frac{57}{4}} [/tex]
[tex] x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2} [/tex]
Ron has 24 coins with a total value of $3.00. The coins are nickels (5 cents) and quarters (25 cents). How many of each coin does he have?
Ron has__ nickels and __ quarters.
Answer:
Ron has 15 nickels and 9 quarters
Step-by-step explanation:
Create a system of equations where n is the number of nickels and q is the number of quarters he has:
n + q = 24
0.05n + 0.25q = 3
Solve by elimination by multiplying the top equation by -0.25
-0.25n - 0.25q = -6
0.05n + 0.25q = 3
Add them together and solve for n:
-0.2n = -3
n = 15
So, Ron has 15 nickels. Find how many quarters he has by subtracting 15 from 24:
24 - 15
= 9
So, Ron has 15 nickels and 9 quarters.

The Indian coolies and the ex-slaves, who resented these newcomers flooding into the colonies and driving down wages, were instant rivals. This was convenient for the planters—who were skilled at the game of divide and rule. The planters lumped their workers into two distinct but equally nasty stereotypes: Former slaves were described as lazy, whereas Indians were called meek, docile children. "You may have work and plenty of it for a black man and a coloured man, and they will not do it,” claimed planter W. Alleyne Ireland. He conveniently ignored the fact that the ex-slaves wanted to work their own land, not labor for their former owners. The overseers praised the Indians' meekness but also held them in contempt. The Indian, one overseer claimed, "possesses the low, cringing and abject habit common to his nationality." What evidence do the authors include to support the central idea that Indian workers and formerly enslaved people became rivals? anecdotal evidence that Indian workers and formerly enslaved people were paid wages on different scales empirical evidence that planters ignored the fact that formerly enslaved people wanted to work their own land empirical evidence that planters tried to pit formerly enslaved people against Indian workers to the planters’ advantage logical evidence that Indian workers and formerly enslaved people did not get along with one another because wages went down
Answer:
empirical evidence that planters ignored the fact that formerly enslaved people wanted to work their own land
