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 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
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

Someone help me with this one
Answer:
Subtract 1/3 from 2/3 dont forget to add the variable h!
1/3h + 11 = 8
-11 -11
1/3h = -3
Now we multiply by 3 on both sides
H = -9
Which phrase represents the algebraic expression for r + 12?
A. The difference of a number and twelve.
B. The product of a number and twelve.
C. The quotient of a number and twelve.
D. The sum of a number and twelve.
Answer: D) The sum of a number and twelve
==================================================
Explanation:
r = an unknown number
r+12 = sum of the unknown number and 12
The term "sum" refers specifically to the result of an addition problem.
As another example, saying 2+3 = 5 has a sum of 5.

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)
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

The lengths of the 2 diagonal of a rhombus are 24cm and 32cm what is the length of one side of the rhombus.
Answer:
[tex]height = \frac{24}{2} = 12 \: cm \\ adjacent = \frac{32}{2} = 16 \: cm[/tex]
We get a triangle of height 12 cm and adjacent 16 cm
[tex]side = \sqrt{ {12}^{2} + {16}^{2} } \\ = \sqrt{400} \\ = 20 \: cm[/tex]
Answer:
side=√(24/2)²+(32/2)²
=√12²+16²
=√400

i cant resolve this equation : 2x = -2x + 8, can you help me please
Answer:
x = 2
Step-by-step explanation:
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
correct

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

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
x = [tex]\sqrt{5.22163^{2} +9.0973^{2} -2*5.22163*9.0973*cos(80)[/tex]
x = 9.7

Step-by-step explanation:
A number is chosen at random from 6 to 25. Find the probability of selecting an even number or multiple of 3.
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.
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

A triangle has side lengths of
3, 7, and 10
Answer:
Possible
Step-by-step explanation:
The rule for triangle side lengths is that the two shortest sides must add up to the longest side so it is possible because
3+7 = 10
Two short sides = The longest side
Answer:
possible
Step-by-step explanation:
3+7= 10
The vertices of rectangle ‘ABCD’ are A(3, 1), B(-5, 1),
C(-5, -3), and D. What are the coordinates of D?
- (3,-3)
-(-3,3)
-(3,3)
-(-3,-3)
Answer:
C (3;-3)
Step-by-step explanation:
when you put the points on the orthonormal, try to write the parallel of BD, passing through A. then the parallel of AB passing through D. you will detect that it's a rectangle that have 4 angles. which is correct
