Step-by-step explanation:

Given the matrix:

A = [4   12

       1   10]

its determinant is: 4*10 - 1*12 = 28

the inverse of A is:

1/28*[10  -12

        -1    4]    

[10/28  -12/28

-1/28    4/28]    

A^-1 = [5/14  -3/7

          -1/28  1/7]

a: 5

b: -3

c: -1

d: 1

Given the matrix:

A = [4   12

      1   10]

its determinant is: 4(10) - 1(12) = 28

Now

the inverse of A is:

1 ÷ 28 × [10  -12

       -1    4]    

[10 ÷ 28  -12 ÷ 28

-1 ÷ 28    4 ÷ 28]    

A^-1 = [5÷  14  -3 ÷ 7

         -1÷  28  1 ÷  7]

The number of items carol can buy is 225.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that Carol bought some items at a variety store. All the items were the same price, and she bought as many items as the price of each item in cents. The items cost 10 cents, she would have bought 10 of them.) Her bill was $2.25.

The number of the items will be calculated as below:-

1 dollar = 100 cents

2.25 dollars = 2.25 x 100 cents

2.25 dollars = 225 cents.

It is given that the number of items bought is equal to the number of cents.

Therefore, the number of items carol can buy is 225.

Answer:

speed of commuter bus: 32 km

speed of passenger car  : 48 mph

Step-by-step explanation:

We will use the concept of speed distance and time.

where time = distance / speed

____________________________________________________

Let the speed of commuter bus be x mph

Given that passenger car travels 16 mph faster than commuter bus.

Speed of passenger car if speed of commuter bus is x mph (x+16)mph

Distance traveled by commuter bus  = 56 miles

Time taken by commuter bus  to travel 56 miles = 56/X   (1)

Distance traveled by passenger car  = 84 miles

Time taken by passenger car to travel 84 miles = 84/(X+16)   (2)

__________________________________________

It is given that time taken by both bus and car is same

so equating equation  1 and 2

we have

56/X = 84/(X+16)   (by cross multiplication we have)

=> 56(X+16)  = 84*X

=> 56X + 896 = 84X

=> 896 = 84X - 56 X

=> 896 = 28X

=> X = 896/28 =  32.

Therefore , speed of commuter bus is x mph or 32 km

speed of passenger car  is x+16 mph = (32+16) mph = 48 mph

Final answer:

The passenger car travels at 48 mph, while the commuter bus travels at 32 mph, derived from the fact that they travel the same time but different distances.

Explanation:

To find the speeds of the passenger car and the commuter bus, we can use the formula for distance (distance = speed × time). Since both the bus and the car travel for the same amount of time, we can set up an equation to solve for their speeds based on the distances they travel.

Let x be the speed of the commuter bus in mph. Consequently, the speed of the passenger car would be x + 16 mph. According to the information given:

The bus travels 56 miles.

The car travels 84 miles.

Since they travel for the same time t, we have:

Bus: 56 miles = x × t

Car: 84 miles = (x + 16 mph) × t

Dividing the mileage of the car by the bus gives us:

[tex]\(\frac{84}{56} = \frac{(x + 16)t}{xt}\)[/tex]

[tex]\(1.5 = \frac{x + 16}{x}\)[/tex]

Multiplying by x to get rid of the fraction and then solving for x provides:

1.5x = x + 16

0.5x = 16

x = 32 mph

This means the bus travels at 32 mph and the passenger car travels at:

32 mph + 16 mph = 48 mph

Therefore, the speed of the passenger car is 48 mph and the speed of the commuter bus is 32 mph.

Answer:

The length of the arc is 221π/18 ft or 38.55 ft

Step-by-step explanation:

Given

Subtended angle, θ = 17π/18

Radius, r = 13 ft

Required

Length of the arc.

When an angle is given in radians, the length of the arc is calculated using the formula below

Length = rθ

By substituting

Length = 13 * 17π/18

Length = 221π/18

The answer can be left in this form.

But for simplification purpose, I'll solve further.

Taking π as 3.14

Length = 221 * 3.14/18

Length = 693.94/18

Length = 38.552222

Length = 38.55 ft (Approximated).

Hence, the length of the arc is 221π/18 ft or 38.55 ft

The Normal condition for constructing confidence intervals is met if both np and n(1-p) are greater than 10. In Candice's case, both conditions are met, so she can proceed with constructing a confidence interval for the proportion of freshmen who like sports drinks.

In order to determine if the Normal condition for constructing confidence intervals is met, we need to check if both np and [tex]\( n(1-p)[/tex] are greater than 10. Here n is the sample size and p is the sample proportion.

For Candice's sample:

Now, calculate np and n(1-p):

Both values (18 and 57) are greater than 10, so the Normal condition is met. Therefore, it is appropriate to proceed with constructing a confidence interval for the proportion of freshmen who like sports drinks.
