Answer:

5 mi  1432 yds

Step-by-step explanation:

   8mi 200 yds

- 2 mi 528 yds

---------------------------

We have to borrow 1 mile and convert to yards

1 mile = 1760 yds

 7mi 200+1760 yds

- 2 mi 528 yds

---------------------------

 7mi  1960 yds

- 2 mi 528 yds

---------------------------

5 mi  1432 yds

Answer:

8mi 200yds - 2mi 528yds

= 5mi 1432yds

Step-by-step explanation:

1 mile = 1760 yards

8 miles = 7miles + 1 mile = 7 miles + 1760 miles = 7 miles 1760 yards

8miles 200 yards = 7miles + 1760 yards + 200 yards = 7miles + 1960 yards

then:

8mi 200 yds - 2 mi 528 yds = 7mi 1960yds - 2mi 528yds

 7mi 1960yds

- 2mi   528yds

Brian is 6 years old, John is 9 years old

Step-by-step explanation:

i.

J = 3 + B

J x B = 54

ii.

(3 + B) x B = 54

B² + 3B = 54

iii.

(B + 9)(B - 6) = 0

B = -9 or 6 -- -9 is irrational as one cannot be negative years old

Brian = 6 years old; therefore, John = 9 years old

Answer:

12100

Step-by-step explanation:

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985

In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990

The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;

B ( t ) = − 329.4 t + 13747

B(5) = -329.4(5) + 13747

B(5) = -1647+13747

B(5) = 12100

This shows that there will be 12100 federally insured banks are there in the year 1990.

Answer:

Step-by-step explanation:

Given

E = { a , c , f }

A = { a , c , j }

i) Let's find the intersection of E and A

E ∩ A = { a , c , f } ∩ { a , c , j }

Answer:

Part A speed=96*2=192km/h

Step-by-step explanation:

Two parts, parts A and part B

Part A=200% more than B

Let part B=x

Part A=200 more than B

=2x

Speed ratio=2:1

Average speed of train=64km/h

Let Part A speed=2x

Part B speed=x

A:B=2:1

Total ratio =3

Speed in the part A can be calculated thus:

Totatl speed= ratio of speed in part A / total ratio

64=2x/3

192=2x

x=96km/h

Part A speed=96*2=192km/h

Answer:

-11/24

Step-by-step explanation:

5/12 - 7/8

We need to get a common denominator of 24

5/12 *2/2  - 7/8 *3/3

10/24 - 21/24

-11/24

Answer:

-11/24

Step-by-step explanation:

Well to solve 5/12 - 7/8 we need to find the LCM.

12 - 12, 24, 36, 48

8 - 8, 16, 24, 32, 40

So the LCM is 24.

Meaning we need to make both denominators 24.

12*2 = 24 5*2 = 10

10/24

8*3 = 24 7*3 = 21

21/24

10/24 - 21/24

= -11/24

Thus,

the answer is -11/24.

Answer:

1/5

Step-by-step explanation:

B, C, D, E, F, G, H, I, J,  K. = 10 tiles

E and I are vowels

P ( vowel) = vowels/ total

                =2/10

                = 1/5

In total, we are given 10 letters.

The vowers are; A, E, I, O, and U

In the bag, we can see we have 2 vowels (E and I)

This means that 2 out of the 10 letters are vowels (2/10).

We can simplify the fraction by dividing by 2.

2÷2/10÷2

1/5

Therefore, the answer is 1/5.

Answer:

The probability of randomly pulling from the bag in the order that spells DESIGN = 1/720

= 0.001389 or 0.1389%

Step-by-step explanation:

The letters placed in a bag = 6

The different ways to choose six letters are a permutation without repetition

And permutation without repetition

= 6 x 5 x 4 x 3 x 2 x 1 = 720 ways

Therefore, the probability of randomly pulling from the bag in the order that spells DESIGN

= 1/720

= 0.001389 or 0.1389%

Probability is defined as the chance that the spelling DESIGN will be pulled from a bag containing the letters: G, E, N, I, D, S, which has 720 ways to choose the letters.

Hi there! :)

Answer:

y = 3x - 17.

Step-by-step explanation:

To write an equation parallel to y = 3x - 8, we need the slope as well as the coordinates of a point to solve for the "b" value in y = mx + b:

A line parallel to y = 3x - 8 contains the same slope, or m = 3.

Plug in the coordinates in (4, -5) into "x" and "y" in the equation y = mx + b respectively:

-5 = 3(4) + b

-5 = 12 + b

Simplify:

-5 - 12 = b

b = -17.

Rewrite the equation:

y = 3x - 17.

Answer:

(a) H0:μ1=μ2; Ha:μ1≠μ2, which is a two-tailed test.

Step-by-step explanation:

We formulate the

H0: μ1=μ2; null hypothesis that the two means are equal and alternate hypothesis that the two mean are not equal.

Ha:μ1≠μ2 Two tailed test

Test statistic used is

t= x1`-x2` / s√n as the variances are equal and sample size is same

T value for 9 degrees of freedom for two tailed test at α = 0.05 is 2.26

P- value for t test for 9 degrees of freedom is 0.125 from the table.

Step-by-step explanation:

D is 72° because it alternates with B, alternate angles are equal.

4x+72°=180°

4x=108°

x=27°

Answer:

62 degrees

Step-by-step explanation:

As two sides shown are same in length thus angle containing by them will be also same.

Thus, other unmarked angle will also be x degrees.

one angle is 56 degrees

we know that sum of angle of triangle is 180 degrees.

Thus

x + x + 56 = 180

2x + 56 = 180

2x = 180 - 56 = 124

x = 124/2 = 62

Thus, value of x is 62 degrees.

Answer:

a. H0 : p ≤ 0.11 Ha : p >0.11 ( one tailed test )

d. z= 1.3322

Step-by-step explanation:

We formulate our hypothesis as

a. H0 : p ≤ 0.11 Ha : p >0.11 ( one tailed test )

According to the given conditions

p`= 31/225= 0.1378

np`= 225 > 5

n q` = n (1-p`) = 225 ( 1- 31/225)= 193.995> 5

p = 0.4 x= 31 and n 225

c. Using the test statistic

z=  p`- p / √pq/n

d. Putting the values

z= 0.1378- 0.11/ √0.11*0.89/225

z= 0.1378- 0.11/ √0.0979/225

z= 0.1378- 0.11/ 0.02085

z= 1.3322

at 5% significance level the z- value is ± 1.645 for one tailed test

The calculated value falls in the critical region so we reject our null hypothesis H0 : p ≤ 0.11 and accept  Ha : p >0.11 and  conclude that the data indicates that the 11% of the world's population is left-handed.

The rejection region is attached.

The P- value is calculated by finding the corresponding value of the probability of z from the z - table and subtracting it from 1.

which appears to be 0.95 and subtracting from 1 gives 0.04998
