Step-by-step explanation:

try 12.50x25% i think

Answer:

25.00 and 50

Step-by-step explanation:

Answer:

y = 125x + 75

Step-by-step explanation:

Let x represents the week and

Let y represent the balance

When x = 2, y = 325.

This means

(x1,y1) = (2,325)

When x = 5, y = 700

This means

(x2,y2) = (5,700)

Required

Determine the equation

First, we need to solve for m, the slope

m = ∆y/∆x

i.e.

m = (y2 - y1)/(x2 - x1)

Substitute values for x and y

m = (700 - 325)/(5 - 2)

m = 375/3

m = 125

Next, we calculate the equation in slope intercept form using

y - y1 = m(x - x1)

Substitute values for m, x1 and y1

y - 325 = 125(x - 2)

y - 325 = 125x - 250

Collect like terms

y = 125x - 250 + 325

y = 125x + 75

Hence, the equation is:

y = 125x + 75

Answer: x=-125+950

Step-by-step explanation:

The value went from 700 to 325 in 3 weeks

700-325= 375 /3 =125

0=950

1=825

2=700

3=575

4=450

5=325

Answer:

The total plots of vegetable cloud will have: 19

Step-by-step explanation:

As the cloud has:

So, the total plots of vegetable cloud will have:

[tex]8\frac{4}{15}+5\frac{1}{3}+5\frac{2}{5}[/tex]

[tex]=\frac{124}{15}+\frac{16}{3}+\frac{27}{5}[/tex]

[tex]=\frac{124}{15}+\frac{80}{15}+\frac{81}{15}[/tex]

[tex]=\frac{124+80+81}{15}[/tex]

[tex]=19[/tex]

Therefore, the total plots of vegetable cloud will have: 19

i took a test that had a question that was the same

Answer:

213.4 tenths

Step-by-step explanation:

It's not 3 probably because the question is asking how many tenths are in the whole number, and not just one section. So, there would be 213.4 tenths.

heres the answer

Step-by-step explanation:

Answer:

150 degrees

Step-by-step explanation:

(Sorry, I know you don't want one but I posted this and then started editing it so hopefully you saw the answer already and I'm not delaying you or anything)

The interior of a quadrilateral always adds up to 360 degrees. y+80 = 180 degrees since they're on a straight line.

We have 3 angles: y = 100, 50, and 60.

360 - (100+50+60)

= 360 - 210

= 150

Answer:

C

Step-by-step explanation:

Convert to improper fraction and multiply them, then convert back to mixed fraction :)

Answer:

C .      The answer can be simplified but its not on here for some reason.

Step-by-step explanation:

6 2/6 x 1 1/2

(6 x 6) + 2 = 38/6

(1 x 2) + 1 = 3/2

38/6 x 3/2 = 114/12

114 ÷ 12 = 9 6/12.

9 6/12 = 9 3/6 = 9 1/2.

C

Again it can be simplified buts it not on here for some reason.

Step-by-step explanation:

This question is incomplete, the complete question is;

A 90% confidence interval for the mean height of a population is 65.7 < μ < 67.3

This result is based on a sample of size 169.

Construct a 99%confidence interval.

Answer: at 99%, confidence interval is [ 65.2, 67.8 ]

Step-by-step explanation:

Given that;

confidence level = 90%

∝ = 1 - 90% = 1 - 0.9 = 0.1

the mean height of a population is 65.7 < μ < 67.3

so

x" - t_∝/2, n-1{standard Error] = 65.7  ----let this be equation 1

x" + t_∝/2, n-1{standard Error] = 67.3 -----let this be equation 2

where t∝/2, n-1 = t_0.1/2, 169 - 1 = t_0.05, 168 = 1.654    (t table)

now we add equation one and equation two

2x" = 65.7 + 67.3 = 133

x" = 66.5

next we subtract equation one from equation two

(x" + t_∝/2, n-1{standard Error]) - (x" - t_∝/2, n-1{standard Error])

= 67.3 - 65.7 = 1.6

so

2 × t_∝/2,n-1 × standard Error  = 1.6

standard Error = 1.6 / (2 × t_∝/2,n-1)

we substitute

Standard Error = 1.6 / ( 2 × 1.654 ) = 1.6 / 3.308 = 0.48367

Now 99% confidence interval for μ is given as;

∝ = 1 - 0.99 = 0.01

x" ± t_∝/2, n-1{standard Error]

(x" ± t_0.01/2, 169-1 [standard Error])

where t_0.005, 168 = 2.6054  (t table)

now for Lower Bound: (x" - t_0.005, 168 [standard Error])

Lower Bound : ( 66.5 - (2.6054 × 0.48367))

= 66.5 - 1.26015 = 65.2398

Upper Bound : ( 66.5 + (2.6054 × 0.48367))

= 66.5 + 1.26015 = 67.7602

Therefore at 99%, confidence interval is [ 65.2, 67.8 ]

Answer:

The anti-derivative of f(x) will be:

[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]

Step-by-step explanation:

Given the function

[tex]\:f\left(x\right)=10x^4\:+\:12.5[/tex]

Taking the anti-derivative of f(x)

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:[/tex]

[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]

Solving

[tex]\int 10x^4dx[/tex]

[tex]\mathrm{Take\:the\:constant\:out}:\quad \int a\cdot f\left(x\right)dx=a\cdot \int f\left(x\right)dx[/tex]

[tex]=10\cdot \int \:x^4dx[/tex]

[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]

[tex]=2x^5[/tex]

similarly,

[tex]\int 12.5dx[/tex]

[tex]\mathrm{Integral\:of\:a\:constant}:\quad \int adx=ax[/tex]

[tex]=12.5x[/tex]

so substituting these values

[tex]\int \left(10x^4\:+\:12.5\right)\:dx\:=\int \:10x^4dx+\int \:12.5dx[/tex]

                                [tex]=2x^5+12.5x[/tex]

                               [tex]=2x^5+12.5x+C[/tex]   ∵ Add constant to the solution

Therefore, the anti-derivative of f(x) will be:

[tex]\int \:10x^4+12.5dx=2x^5+12.5x+C[/tex]
