Answer:

k = 0.5

Step-by-step explanation:

Substitue y = 12, x = 24 into y = kx.

12 = k × 24

24k = 12

k = 12 ÷ 24

k = 0.5 (final answer)

Answer:

the value of k is

k = 1/2

Step-by-step explanation:

from the question y = kx,

where y = 12 and x = 24

we will first of all make k the subject of the formula

y = kx

divide both sides by the coeficient of k which is x

y/x = kx/x

y/x = k .................................. k is the constatnt of proportionality

since we are given the value of x and y , we slot it in to determine the value of k.

k = y/x

k = 12/24

k = 1/2

check if your answer is correct , put the value of k into te question and see if LHS = RHS

y = kx

12 = 1/2 × 24

12  = 24/2

12 = 12....................... PROVED

adell [148]
In this item, we are tasked to determine the calculation that can be done in order to determine the length or width of the painted mural in each striped area. This can be done by dividing the total length by the number of stripes as shown in the equation below.

   Length per stripe = Total length / number of stripes
    Length per stripe = 15 yards / 96 stripes
                           = 0.15625 yard/stripe

Answer:

y=-6.6 and y=10.6

Step-by-step explanation:

The given ellipse has equation:

\frac{(y-2)^2}{64}+\frac{x^2}{9}=1.

The center of this ellipse is (h,k)=(0,2)

We use the equation: a^2-b^2=c^2 to determine the foci.

\implies 64-9=c^2

\implies 55=c^2

\implies c=\pm \sqrt{55}

The directrices are given by y=k\pm\frac{a^2}{c}

y=2\pm\frac{64}{\sqrt{55}}

y=2\pm8.6

y=2-8.6 and y=2+8.6

The equation of the directrices are:

y=-6.6 and y=10.6

The correct answer is D

Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years. Use I= part
sammy [17]

Answer:

The amount of interest is $5580.            

Step-by-step explanation:

Given : Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years.

To find : The amount of interest he will pay with the loan ?

Solution :

Using interest formula,

I=P\times R\times T

Where, P is the principal P=$30,000

R is the rate of interest R=6.2%=0.062

T is the time t=3 years.

Substitute the value in the formula,

I=30000\times 0.062\times 3

I=5580

Therefore, The amount of interest is $5580.

In-s [12.5K]

Answer:

is an attachment

test statistic = 9.87

p value is less than 0.01

Not all means of the three assembly methods are equal

Step-by-step explanation:

the anova table is an attachment

total number of methods = k = 3

number of observations n = 30

for treatment, df = 3-1 = 2

for error, df = 30 -3 (n-k) = 27

sst = 10800, sstr = 4560, sse = 10800-4560 = 6240

we find the mean of squares for error

sse/df of error = 6240/27 = 231.11

mean of squares for treatment = 4560/2 = 2280

test stat

F = 2280/231.11

= 9.8654

using f distribution table;

alpha = 0.05

df = 2 , 27

we get 3.35

h0; no difference in mean

h1; there is difference

9.87 > 3.35 so we reject H0, there is difference in means. all are not equal.

pvalue calculation

using excel,

FDIST(9.8654, 2, 27) = 0.0006078

p value is less than 0.01

we conclude that a. Not all means of the three assembly methods are equal
