The probability that the next report will weigh less than 45 grams = 0.106

In this question, we have been given the weight of written reports produced in a certain department has a normal distribution with mean 60 grams and standard deviation 12 grams.

We need to find the probability that the next report will weigh less than 45 grams.

We have mean= 60 grams

Standard Deviation = 12 grams

First we convert 45 to z score.

45 converted to z score for given mean and standard deviation will be:

z = (45 - 60)/12

z = -1.25

So, from standard normal table a P-value:

P(x<45) = 0.10565

Therefore, the probability would be 0.10565

Answer:

2/9 = approximately 0.22.

Step-by-step explanation:

There are a total of 12 possible outcomes when the spinner is spun once, so the probability of getting a result that is not green is 8/12, or 2/3. Similarly, the probability of getting green on the second spin is 4/12, or 1/3.

To find the probability of getting a result that is not green on the first spin and green on the second spin, you can multiply the probabilities of each individual event. Therefore, the probability of getting not green then green is (2/3) * (1/3) = 2/9 = approximately 0.22.

Alternatively, you could also use the principle of complementary probabilities to calculate the probability of getting not green on the first spin and green on the second spin. The probability of getting not green on the first spin is 1 - (4/12) = 8/12 = 2/3, and the probability of getting green on the second spin is still 4/12 = 1/3. Multiplying these probabilities gives a result of (2/3) * (1/3) = 2/9 = approximately 0.22.

Step-by-step explanation:

2 + 3/8 = 7/8

2 x 7/8 = 7/4

2 + 5/8 = 9/8

2 x 9/8 = 9/4

2 + 6/8 = 8/8

2 x 8/8 = 16/8

2 + 7/8 = 15/8

2 x 15/8 = 15/4

The earnings for both Cynthia and Javier are same for x hours.

What is commission?

When an employee completes a task, typically selling a certain volume of goods or services, they are compensated financially. Sales commissions are occasionally used by employers as incentives to boost employee productivity. It is possible to receive a commission in place of or in addition to a salary.

Given:

Cynthia earns $680 in commissions and is paid $10.25 per hour.

Javier earns $410 in commissions and is paid $12.50 per hour.

So, the equation is

10.25x + 680 = 12.5x + 410

To simplify this equation for x.

10.25x+ 680 =12.5x +410

    680 ‐ 410 = 12.5x ‐ 10.25x

             270 = 2.25x

                  x = 270/2.25

                  x = 120

If we plug x = 120 in both the values 10.25x + 680 and 12.5x + 410 then we will get the same values.

Hence, the earnings for both Cynthia and Javier are same for x hours.

The  equations that can be used to solve for the length of the room are

(b) y²-5y=750  ,    (c) 750-y(y-5)=0  and   (e) (y+25)(y-30)=0

Given that:

The area of rectangular room is 750 square feet.

Let the length of the rectangular room be y feet.

Since the width of the rectangular 5 less than the length of the room.

Then the width of the given rectangular room is (y-5) feet.

We know the area of a rectangular plot is = Length×width.

Thus , the area of the rectangular room is = y(y-5) square feet

According to problem,

area of the rectangular room =  750 square feet

⇒ y(y-5) =750.........(1)

⇒ y²-5y=750 .......(2)

⇒ y²-5y-750=0

⇒ y²-30y+25y-750=0

⇒ y(y-30)+25(y-30)=0

⇒ (y-30)(y+25)=0 ......(3)

⇒ y-30=0 or, y+25=0

⇒ y= 30, -25

∵ the length of a rectangle can't be negative.

So, y=30.

We can rewrite the equation (1) in form of

(i)

y(y-5) =750

⇒750= y(y-5)

⇒750-y(y-5)=0.......(4)

(ii)

y(y-5) =750

⇒y(y-5) -750=0.......(5)

Hence , the  equations that can be used to solve for the length of the room are

(b) y²-5y=750  ,    (c) 750-y(y-5)=0  and   (e) (y+25)(y-30)=0

Step-by-step explanation:

For the given statement about hundredth digit of the given decimal z the following statement is true:

Option E. statement (1) and (2) together are not sufficient.

As given in the question,

Let us consider decimal z is represented by k.lmn

Here hundredth digit of z is equal to m

Now,

(1) The tenths digit of 100z is 2.

100z

= 100(k.lmn)

=klm.n

This implies n = 2

(2) The units digit of 1,000z is 2.

1,000z

= 1,000(k.lmn)

= klmn

This implies n =2

From both the statements we are getting the value of n which is not sufficient to get the value of required 'm'.

Therefore, Option E is the correct answer which shows both the statements are not sufficient to get the value required hundredth digit of decimal z.

The complete question is:

What is the hundredths digit of the decimal z ? (1) the tenths digit of 100z is 2. (2) the units digit of 1,000z is 2.

A. Statement (1) alone is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) alone is sufficient, but statement (1) alone is not sufficient.

C. Both statements together are sufficient, but neither statement alone is sufficient.

PLEASE ADD A DANG PICTURE

Step-by-step explanation:

The quadratic equation that models the company's costs is y = 25(x - 16)² + 1000

From the question, we have the following parameters that can be used in our computation:

Minimum cost of $1000 at 16 hours

Operating cost of $2600 at 8 hours

A quadratic equation is represented as

y = a(x - h)² + k

The minimum point is the vertex

So, we have

(h, k) = (16, 1000)

Substitute (h, k) = (16, 1000) in y = a(x - h)² + k

y = a(x - 16)² + 1000

The cost of $2600 at 8 hours means

(x, y)  = (8, 2600)

So, we have

2600 = a(8 - 16)² + 1000

Evaluate the difference

1600 = a(8 - 16)²

So, we have

64a = 1600

Divide by 64

a = 25

Substitute a = 25 in y = a(x - 16)² + 1000

y = 25(x - 16)² + 1000

Hence, the equation is y = 25(x - 16)² + 1000

What is sine rule of a triangle?

AB/sin C = BC/ sin A = AC / sin B

1)

Applying sum rule of interior angle

∠A + ∠B + ∠C = 180°

22° + 118° + ∠C = 180°

∠C = 40°

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting AB = 24, ∠C = 40°, and ∠B = 22°:

AB/sinC=AC/sin B

24/sin 40° = AC/ sin 22°

AC = 13.98

AC ≈ 14

2)

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting AC = 7, ∠B = 44°, and ∠C = 53°:

AC/sin B=AB/sin C

7/sin 44° = AB/ sin 53°

AB = 8.047

AC ≈ 8

3)

Applying sum rule of interior angle

∠A + ∠B + ∠C = 180°

39° + ∠B +  51°= 180°

∠B = 90°

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting AC = 27, ∠B = 90°, and ∠A = 39°:

BC/sinA=AC/sin B

BC/sin 39° = 27/ sin 90°

BC = 16.99

BC ≈ 17

4)

Applying sum rule of interior angle

∠A + ∠B + ∠C = 180°

∠A + 101° +  63°= 180°

∠A = 16°

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting CB = 9, ∠A = 16°, and ∠C = 63°:

AB/sinC=BC/sinA

AB/sin 63° = 9/ sin 16°

AB = 29.09

AB ≈ 29.1

5)

Applying sum rule of interior angle

∠A + ∠B + ∠C = 180°

93° + ∠B + 58°  = 180°

∠B = 29°

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting AC = 16, ∠B = 29°, and ∠A = 93°:

AC/sinB=BC/sin A

16/sin 29° = BC/ sin 93°

BC = 32.95

BC ≈ 33

6)

Applying sine law in △ABC:

AB/sinC=BC/sinA=AC/sin B

Putting AB = 21, ∠A = 88°, and BC= 26:

AB/sinC=BC/sinA
