6.28 hours

Step-by-step explanation:

103880/18.55 = 35168/x

103880x = 652366.4

x = 6.28

6.28 hours or 6 hours 28 minutes

Answer:

I = $ 220.00

Step-by-step explanation:

I = $ 220.00

Equation:

I = Prt

Solve:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 2200 × 0.05 × 2 = 220

I = $ 220.00

The simple interest accumulated

on a principal of $ 2,200.00

at a rate of 5% per year

for 2 years is $ 220.00.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Time taken = 2 hours 18 minutes

18 / 60 = 0.3 hours

Hence, time taken = 2.3 hours

Speed = distance / time

Speed = 26.2 / 11.3 = 11.39 mi/hr

Hence, according to the mean value theorem ;

The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39

Since initial and final velocity is 0 ;

The runner attains a speed of 11 mi/hr between :

(0, 2.3) and (t, 2.3)

Mr. O. ran the Disney Marathon the AB AP is  (0, 2.3) and (t, 2.3).

        Time taken =18 / 60

        Time taken = 0.3 hours

Hence,

time taken = 2.3 hours

          Speed = 26.2 / 11.3

          Speed = 11.39 mi/hr

According to the mean value theorem ;

The range of time taken is (0, 2.3) whereby a certain time, t exist when the runner attains a speed of 11.39 Since initial and final velocity is 0 ;

The runner attains a speed of 11 mi/hr between : (0, 2.3) and (t, 2.3)

Thus, the AB and AP is (0, 2.3) and (t, 2.3)

Answer:

0.6864 = 68.64% probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

Step-by-step explanation:

The cars are chosen without replacement, so the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

48 new cars being shipped to local dealerships, corporate reports indicate that 12 have defective radios installed.

This means that [tex]N = 48, k = 12[/tex]

8 cars received.

This means that [tex]n = 8[/tex]

What is the probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

This is

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

In which

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,48,8,12) = \frac{C_{12,0}*C_{36,8}}{C_{48,8}} = 0.0802[/tex]

[tex]P(X = 1) = h(1,48,8,12) = \frac{C_{12,1}*C_{36,7}}{C_{48,8}} = 0.2655[/tex]

[tex]P(X = 2) = h(2,48,8,12) = \frac{C_{12,2}*C_{36,6}}{C_{48,8}} = 0.3407[/tex]

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0802 + 0.2655 + 0.3407 = 0.6864[/tex]

0.6864 = 68.64% probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

Answer:

[tex]\frac{3}{8}[/tex] Or 0.375

Step-by-step explanation:

From the picture attached,

A circle is divided into 8 sections.

Out of which 3 sections have been shaded.

So the ratio of the shaded sections to the total number of sections will be,

3 : 8

Therefore, fraction representing the ratio will be = [tex]\frac{3}{8}[/tex]

And the decimal form of the fraction will be = 0.375

Answer:

The 95% CI on the proportion of seeds that germinate is (0.89, 0.9256).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Of the 180 seeds that I planted, only 167 germinated.

This means that [tex]n = 180, \pi = \frac{167}{180} = 0.9278[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9278 - 1.96\sqrt{\frac{0.9278*0.0722}{180}} = 0.89[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9278 + 1.96\sqrt{\frac{0.9278*0.0722}{180}} = 0.9256[/tex]

The 95% CI on the proportion of seeds that germinate is (0.89, 0.9256).

This question is incomplete, the complete question is;

Suppose u and v are functions of x that are differentiable at x=0

and that { u(0) = 7, u'(0) = -5 }  { v(0)= -1, v'(0) = -4 }

Find the values of the following derivatives at x = 0.

a) [tex]\frac{d}{dx}[/tex]( uv )

b)  [tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )

c)  [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )

Answer:

a) [tex]\frac{d}{dx}[/tex]( uv ) = -23  

b) [tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33

c) [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = -32/49 or - 0.6531

Step-by-step explanation:

Given that;

{ u(0) = 7, u'(0) = -5 }  { v(0)= -1, v'(0) = -4 }

a)

[tex]\frac{d}{dx}[/tex]( uv )

we differentiate

[tex]\frac{d}{dx}[/tex]( uv )  = uv' + vu'

at x = (0), we substitute our values

[tex]\frac{d}{dx}[/tex]( uv ) = ( 7 × -4 ) + ( -1 × -5)

[tex]\frac{d}{dx}[/tex]( uv )  = -28 + 5

[tex]\frac{d}{dx}[/tex]( uv ) = -23  

b)

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )

we differentiate

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = ( vu' - uv' ) / v²

at x=0, we substitute our values

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = ( (-1 × -5) - (7 × -4 ) ) / (-1)²

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = (( 5 - ( -28 )) / 1

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33 / 1

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33

c) [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )

we differentiate

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( uv' - vu' ) / u²

at x=0, we substitute our values

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( (7 × -4) - (-1 × -4) ) / (7)²

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = ( -28 - ( 4 ) ) / 49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( -28 - 4 ) /49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = -32 / 49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = -32/49 or - 0.6531
