Answers

Answer 1

Answer: Hello some part of your question is missing below is the missing part

Missing question:  Find the probability that the Smith family had at least 6 girls?

answer : 0.1406

Step-by-step explanation:

Number of children = 8

probability of a child being a girl ( success ) = 0.5  (

P( boy ) ( q ) = 1 - 0.5 = 0.5

P( at least 6 girls ) = p(k = 6 ) + p(k = 7 )

                              = 0.109375 + 0.03125 ≈ 0.1406

( using Binomial probability Calculator )

A company determined it could use equation y = -25/3x + 250,000 to predict its total number of customers, y, based on the number of days x. What is the meaning of the slop of this function

Answers

Answer:

The slope is meant to show the relationship between the x(number of days) variable and the y (total number of customers) variable.

When the number is positive, it means that both x and y move in the same direction which means that as x increases, so does y.

When this number is negative, it means that hen x increases, y decreases.

In this scenario therefore, as the number of days increases, the total number of customers decreases.

A 170 ft string attached to a kite makes a 40⁰ angle with the ground. What is the height of the kite to the nearest tenth? 130.2 ft 33 ft 142.6 ft 109.3 ft

Answers

Answer:

109.3 ft

Step-by-step explanation:

Remembering SOHCAHTOA

We would be using sin

sin = opposite / hypotenuse

sin 40 = x / 170

0.6428 = x/170

x =  0.6428  x 170 = 109.3 ft

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

A number is chosen at random from 6 to 25. Find the probability of selecting an even number or multiple of 3.

Answers

Answer:

17/25

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

even numbers between 6 and 25 = 6 8 10 12 14 16 18 20 22 24

multiples of 3 = 6 9 12 15 18 21 24

Jorge's friend Kylie has a garden with 100 flowers in it. Kylie's garden contains tulips and daisies. Is it possible for Kylie's garden to have the same ratio of tulips to daisies as Jorge's garden? Explain why or why not.

Answers

Answer:

Yes, Kylie's can have the same ratio of tulips to daisies as that of Jorge

Step-by-step explanation:

Complete question

Jorge planted flowers in his garden. He planted one row of 12 tulips

and one row of 36 daisies. Jorge's friend Kylie has a garden with 100 flowers in it. Kylie's garden contains tulips and daisies. Is it possible for Kylie's garden to have the same ratio of tulips to daisies as Jorge's garden? Explain why or why not

Solution

Ratio of Tulip to daises in Jorge garden is 12:36 = 1:3

Here the common factor is 12 for numerator and denominator i.e 4 * 3 or 2, 2, 3

Given, Jorge's friend Kylie has a garden with 100 flowers, 100 is divisible by 4 but not 3.

Hence, if we take  Ratio of Tulip to daises in Jorge garden as 3:9 (by only removing common factor 4), then the Ratio of Tulip to daises in Kylie  garden will have the same ratio is that of Jorge'sgarden

Answer: 9.7

Step-by-step explanation: I got this question right

70+30 = 100

B = 180 - 100 - 20

B = 60°

80+20 = 100

C = 180 - 100 - 30

C = 50

DB/sin100 = 8/sin(60)

8*sin(100)/sin(60)

DB = 9.0973

DC/sin(30) = 8/sin(50)

8*sin(30)/sin(50)

DC = 5.22163

Part II: Using the variable you defined in Part I, write an expression to represent the
amount of money Sam will spend in one year (Sam's cost). (2 points)

Answers

Answer:

Number of wooden carving = a

Total amount Sam spend = 1,200 + 4a

Total revenue of Sam = 15a

Number of wooden carving make to earn profit $4,300 = 500 carvings

Step-by-step explanation:

Given:

Sales price of each wooden carving = $15

Fixed cost = $1,200

Variable cost = $4 for each

Find:

Number of wooden carving make to earn profit $4,300

Computation:

Part 1

Assume

Number of wooden carving = a

Part 2

Total amount Sam spend = 1,200 + 4a

Part 3

Total revenue of Sam = 15a

Part 4

Total profit of Sam = Total revenue of Sam - Total cost of Sam

4,300 = 15a - [1,200 + 4a]

4,300 = 15a - 1,200 - 4a

11a = 5,500

a = 5,500 / 11

Number of wooden carving make to earn profit $4,300 = 500 carvings

Un cuerpo de 180 kg se debe lanzar hacia una distancia de 25 m. ¿Qué valor tiene el trabajo que se realiza al lanzarlo?

Answers

Answer:

45, 000 J o 45 KJ

Step-by-step explanation:

Recordemos que trabajo realizado = fuerza * distancia

En este caso, fuerza = peso del objeto

Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N

Por eso;

Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ

i cant resolve this equation : 2x = -2x + 8, can you help me please

OK so lets do it together.

2x = -2x + 8

Subtract 8 from both sides

2x - 8 = -2x

Add 2x to both sides

4x - 8 = 0

Add 8 to both sides

4x = 8

Divide each side by 4

x = 2

Check:

4 = -4 + 8

4 = 4
