Answer:
b)15.75 and 2.9432
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean of a binomial distribution is:
[tex]\mu[/tex] = np
And the standard deviation is
[tex]\sigma[/tex] = √(npq)
where,
n = 35,
p = 0.45,
and q = 1 - 045 = 0.55
Now mean is
= 35 × 0.45
= 15.75
And, the standard deviation is
= √(35 × 0.45 × 0.55)
= 2.9432
Hence, the correct option is B.

A plane is traveling at a constant speed of K miles per hour. Which coordinate is
represented on the graph?
A. 1,K
B. K,K
C. K,1
Brainly
Answer:
Option (A)
Step-by-step explanation:
Plane is travelling at a constant speed = K miles per hour
K = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Distance = k(Time)
For Time of traveling = 1 hour
Distance traveled = k × 1
= k miles
Therefore, k miles will be traveled in one 1 hour and ordered pairs of the given point on the line will be (1, k)
Option (A) will be the correct option.
Jenna is putting a ribbon around the border of a square frame. The area of the frame is 196 square inches. How long will the ribbon need to be in order to go around the whole frame?
Answer: 56 inches
Step-by-step explanation:
Given that:
Area of square frame = 196 in²
Area of a square = a²
Where a = side length
Hence side length (a) of the square :
a² = 196
a = √196
a = 14
To find the length of the ribbon required :
Find the perimeter of the square :
Perimeter of a square = 4a
= 4 * 14
= 56 inches
GIVEN: LJ || WK || AP, PL || AG.
PROVE: Angle 1 is congruent to angle 2
#12 pleaseee
20 points!!
Answer:
∠1 ≅ ∠2 ⇒ proved down
Step-by-step explanation:
#12
In the given figure
∵ LJ // WK
∵ LP is a transversal
∵ ∠1 and ∠KWP are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠1 = m∠KWP
∴ ∠1 ≅ ∠KWP ⇒ (1)
∵ WK // AP
∵ WP is a transversal
∵ ∠KWP and ∠WPA are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠KWP = m∠WPA
∴ ∠KWP ≅ ∠WPA ⇒ (2)
→ From (1) and (2)
∵ ∠1 and ∠WPA are congruent to ∠KWP
∴ ∠1 and ∠WPA are congruent
∴ ∠1 ≅ ∠WPA ⇒ (3)
∵ WP // AG
∵ AP is a transversal
∵ ∠WPA and ∠2 are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠WPA = m∠2
∴ ∠WPA ≅ ∠2 ⇒ (4)
→ From (3) and (4)
∵ ∠1 and ∠2 are congruent to ∠WPA
∴ ∠1 and ∠2 are congruent
∴ ∠1 ≅ ∠2 ⇒ proved
do Q11 do carefully step by step
Answer:
The measure of the four angles are 30°, 60°, 120°, 150°
Step-by-step explanation:
Q 11.
The sum of the measures of the angle at a point is 360°
Let us use this fact to answer the question
→ Assume that m∠AOB is x°
∵ m∠AOB = x°
∵ m∠BOC is twice m∠AOB
∴ m∠BOC = 2x°
∵ m∠COD is 4 times m∠AOB
∴ m∠COD = 4x°
∵ m∠DOA is 5 times m∠AOB
∴ m∠DOA = 5x°
→ By using the fact above
∵ m∠AOB + m∠BOC + m∠COD + m∠DOA = 360°
∴ x° + 2x° + 4x° + 5x° = 360°
→ Add the like terms
∴ 12x° = 360°
→ Divide both sides by 12
∴ x = 30°
→ Substitute the value of x in each angle to find them
∵ m∠AOB = x°
∴ m∠AOB = 30°
∵ m∠BOC = 2x° = 2(30°)
∴ m∠BOC = 60°
∵ m∠COD = 4x° = 4(30°)
∴ m∠COD = 120°
∵ m∠DOA = 5x° = 5(30)
∴ m∠DOA = 150°
∴ The measure of the four angles are 30°, 60°, 120°, 150°

As a product development manager, one of your tasks is to determine the best price for an item to increase company profits. To do that, you need to take into account the cost of making the product, the labor of creating the product, and other overhead costs for the company (such as rent, electricity, etc.) If a product uses $14.25 in materials, $3.55 in labor, and $2.15 in overhead costs, what would you need to sell the product for in order to make a 20% profit on the item?
Answer:
$23.95
Step-by-step explanation:
In order to calculate the best selling price we first need to calculate the total amount of costs. Since we are provided with each individual cost we simply need to add these costs together to find the total.
$14.25 + $3.55 + $2.15 = $19.95
Now that we have the total amount of costs, we know that this is the break-even price that the product needs to sell for in order for the company not to lose money. If the company wants to make a 20% profit on each sale then you would need to increase this amount by 20%. This is done by multiplying the total costs by 1.20, which is 20% divided by 100 to turn it into decimal form, and then adding 1 to make it increase the total cost.
$19.95 * 1.20 = $23.95
Therefore, the company needs to sell each item for $23.95 in order to make a 20% profit.

find the slope of a line parallel to each given line y = 1
Answer:
its undefined i believe. theres no x the slope would be 0 but i'm not sure
Step-by-step explanation:
Write an equation for the line?
Answer:
y = 2x + 3
Step-by-step explanation:
Given:
(2, 7) and (0, 3)
Find the slope between the two points:
(x1, y1) = (0, 3)
(x2, y2) = (2, 7)
(y2 - y1)/(x2 - x1)
(7 - 3)/(2 - 0)
4/2 = 2
m = 2
y = mx + a
y = 2x + a
Use one of the two points to find a (I will use point (2, 7):
7 = 2(2) + a
7 = 4 + a
a = 3
Slope-intercept Form: y = 2x + 3
Point-slope Form: y - 3 = 2x
Point-slope Form: y - 7 = 2(x - 2)
General equation: 2x - y + 3 = 0

Two pounds of onions cost $2.30. At this rate, how much will 5 pounds of onions cost?
Answer:
$5.75
Step-by-step explanation:
Find the unit rate first:
[tex]\frac{2.3 dollars}{2 pounds}[/tex]÷[tex]\frac{2}{2}[/tex]=[tex]\frac{1.15}{1}[/tex]
For every onion, you must pay $1.15. Multiply that by 5 in order to find the cost of 5 pounds of onions. It is $5.75. You can do this with any number to find the cost of any amount of pounds of onions. 4x1.15= 4.60 so the cost of 4 pounds of onions would be $4.60. 6x1.15=6.90 so the cost of 6 pounds of onions would be $6.90. Hope this helps.
