Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. What is the probability that all of Erica's flights will be on time? А 36% B 66% С 76% D 86%.
Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.
To answer the question, we need to know what probability is
What is probability?This is the likelihood for an event to occur. It is given by
P(event) = number of required outcomes/total number of outcomes
Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.
Probability that all of Erica's flights will be on time
So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)
= [P(flight)]⁴
= (90%)⁴
= (0.9)⁴
= 0.656
≅ 0.66
= 66%
So, the probability that all of Erica's flights will be on time is B 66%.

a town is 61km north of 23km east of town B.bCalculate the bearing of A from B
Answer:
20.7°
Step-by-step explanation:
Bearing angle is measured clockwise from north. The geometry can be modeled by a right triangle with the sides equal to the distances north and east of town B. The tangent relation can be used to find the angle.
__
The attachment shows the geometry. The relevant angle relation is ...
Tan = Opposite/Adjacent
tanIβ) = 23/61 . . . . . where β is the bearing angle
The angle value can be found using the arctangent function.
β = arctan(23/61) ≈ 20.659°
The bearing of A from B is about 20.7°.

A book has 180 pages. Haley read 12 pages each day.after a certain number of days there are 60 pages left,which equation and solve for X gives the number of days he read
Answer: She read for 10 Days, equation below
Step-by-step explanation:
Number of pages = 180
Rate = 12pages Per day
Number of days read = (180-60) /12
Days read = (total no of page - page left)/page read per day
= 120/ 12 = 10 days
Days remaining = pages left /page per day
=60/ 12 = 5

Choose the appropriate trigonometric ratio and solve for x. Round your answer to the nearest tenth.
Answer:
62.7
Step-by-step explanation:
Cos(ang) = Adjacent / hypotenuse
cos(37) = 48/x
x = 48 / cos(37)
x = 62.71
Answer:
x = 60.1
Step-by-step explanation:
- The provided side length is adjacent to given degree
- and we are lookin for the hypotenuse
SOH CAH TOA stands for,
sinx = opposite / hypotenuse
cosx = adjacent / hypotenuse
tanx = opposite / adjacent
cosine fulfills everything we have provided so we will choose cos
NOTE: x in cosx represent the degree amount
Solving:
cosx = adjacent / hypotenuse
cos(37°) = 48 / x
multiply both sides by x,
cos(37°)x = 48
divided both sides by cos(37°) to get x alone
x = 48 / cos(37°)x
x = 60.1025

Please Vote Me Brainliest. Thank You.
Answer:
48 : 1 or 48 to 1
Step-by-step explanation:
to find out the answer we have to first find out what 8 feet is in inches as shown below
8 * 12 = 96
then we apply the inch value to a scale factor setup where 96 is the larger set and 2 is the smaller image
96 : 2
find the least common denominator...
96 / 2 : 2 / 2
= 48 : = 1
and then rewrite the answer
48 : 1

96 Eight small bricks have the same mass as three large bricks The mass of one small brick is 1.5kg. What is the mass of one large brick?
Answer:
4 kg
Step-by-step explanation:
Since the mass of one small brick is 1.5 kg, the mass of 8 small bricks is 1.5 × 8, or 12 kg. Since 12 kg is the total mass of 3 large bricks, it follows that each large brick will have a mass of 12 ÷ 3, or 4 kg.
the length of a rectangle plus its width is 35 cm the area 306 what are the length and width of the rectangle
Step-by-step explanation:
Let width be w, length be l
l + w = 35, so w = 35 - l
lw = 306
l(35-l) = 306
35l - l^2 = 306
l^2 - 35l + 306 = 0
(l - 17)(l - 18) = 0
l = 17 or 18
When length = 17, width = 35-17 = 18
When length = 18, width = 35-18 = 17

The mean age of 11 women in an office is 19 years old. The mean age of 11 men in an office is 26 years old. What is the mean age (nearest year) of all the people in the office?
Answer:
22.5
Step-by-step explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 11 women, with the mean being 19, we can see that the ages summed to 209:
11 x 19 = 209
And then we can do the same for men:
11 x 26 = 286
And now we can combine the sum and count of the men and women to find the mean for the office:
286 + 209 = 495
495/22 = 22.5
what is 62.5% as a decimal
Answer:
0.625
Step-by-step explanation:
please give me brainliest :(
Answer:
0.625
Step-by-step explanation:
How to Convert a Percent to a Decimal
Here are two ways to convert a percent to a decimal,
1. Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
Example: 62.5% becomes 62.5/100 = 0.625
2. This way is easier and faster. Start by removing the percent sign and moving the decimal point 2 places to the left.
Example: 62.5%
⇒ 62.5
⇒ 6.25
⇒ .625
Hence, the answer is 0.625.

Answer:
B. 254 cm²
Step-by-step explanation:
Hello!
CircleThe formula for the area of a circle is [tex]A = \pi r^2[/tex]
A is areaπ is pi (roughly 3.14)r is the radiusThe radius is half of the diameter, given with the formula [tex]D = 2r[/tex]
AreaUsing the information, we can first solve for the radius.
[tex]D = 2r[/tex][tex]18 = 2r[/tex][tex]9 = r[/tex]The radius is 9
Now we can plug 9 into the area formula:
[tex]A = \pi r^2[/tex][tex]A = \pi (9^2)[/tex][tex]A = 81\pi[/tex]We are going to use 3.14 for pi
[tex]A = 81(3.14)[/tex][tex]A = 254.34[/tex]The area is 254.34cm².
We are going to round to the nearest whole centimeter, which is roughly 254cm² or [tex]\boxed{\text{Option B}}}[/tex]
Does anybody know this? ABCD is a parallelogram BDC=110. Find the following values,
Answer:
see explanation
Step-by-step explanation:
in a parallelogram]
• opposite sides are congruent
• opposite angles are congruent
• consecutive angles are supplementary , sum to 180°
• diagonals bisect each other
Then
DC = AB = 15
BC = 2 × WC = 2 × 9 = 18
∠ BAC = ∠ BDC = 110°
∠ DCA = 180° - 110° = 70°
DC = 15 (opposite sides in a parallelogram is parallel and equal to each other)
BC = 18 (the diagonals in a parallogram bisect at their midpoints -> BW = WC = 9 -> BC = 9 + 9 = 18)
angle BAC = 110 (opposite angles are equal to each other)
angle DCA = 70 (consecutive angles add up to 180, angle BAC and angle DCA are consecutive -> 180 - 110 = 70)
