If the value of y varies directly with x and y= -1 when x=3, find y if x=9

Zolol [24]

y = - 3

Since y varies directly as x then

y = kx ← ( k is the constant of variation )

to find k use y = - 1 when x = 3

k = $\frac{y}{x}$ = $\frac{-1}{3}$ = - $\frac{1}{3}$

hence y = - $\frac{1}{3}$ x

when x = 9, then

y = - $\frac{1}{3}$ × 9 = - 3

A researcher believes that there is a difference in how cautious male stray cats and female stray cats are when approaching peop

Anika [276]

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.

Jake has 32 quarters on his desk, molly has q quarters in her purse.

Which algebraic expression represents the total number of quarters that Jake and Molly have?

we know that

To find out the total number of quarters that Jake and Molly have, sum the amount of quarters that Jake has plus the amount of quarters that Molly has

Let

x ----> the amount of quarters that Jake has

y ----> he amount of quarters that Molly has

x+y

we have

$x=32\ quarters\\y=q\ quarters$
