Two friends argue over who brushes their teeth more often. To settle the argument, they keep track of the number of mornings and nights they brush and calculate a probability. These are shown in the table.
Answers
Using the probability concept, the correct option regarding who is more likely to brush both in the morning and in the evening is:
B. Arabella. She has a 0.64 probability of brushing both times.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Considering that the events are independent, we just multiply the probabilities, hence the probability of each brushing both times is given as follows:
Braxton: 0.85 x 0.72 = 0.612.Arabella: 0.79 x 0.81 = 0.64.Hence statement B is correct, as 0.64 > 0.612.

The equation f equals 9/5 C + 32 relates temperature measured in degrees celsius C to degrees Fahrenheit f Determine whether there is a proportional relationship between C and F explain your reason
Answers
Given:
[tex]F=\dfrac{9}{5}C+32[/tex]
where, F is degree Fahrenheit and C is degree Celsius.
To find:
Whether there is a proportional relationship between C and F.
Solution:
We know that, proportional relations is defined as
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
So, the line of proportional relationship passes through (0,0) and the equation must be true for (0,0).
If there is a proportional relationship between C and F, then the equation must be true for (0,0).
Substituting F=0 and C=0 in the given equation, we get
[tex]0=\dfrac{9}{5}(0)+32[/tex]
[tex]0=0+32[/tex]
[tex]0=32[/tex]
This statement is false because [tex]0\neq 32[/tex].
It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.
Hence, there is not a proportional relationship between C and F.
In a survey of 1,500 people who owned a certain type of car, 300 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answers
Answer:
20%Step-by-step explanation:
Step one:
total number of people surveyed= 1500
we are told that 300 people would buy that car again,
this implies that they like the car and are satisfied with it
Step two:
the percent of people satisfied can be computed as
=300/1500*100
=3/15*100
=1/5*100
=0.2*100
=20%
The people surveyed were satisfied with the car are 20%

Sally bought 124 sheets of stickers. Each sheet had 14 stickers. She gave away 204 stickers to her family and friends on Christmas. How many stickers does Sally have remaining?
Answers
Answer:
Sally has 1,532 stickers remaining.
Step-by-step explanation:
First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:
124*14=1,736
Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:
1,736-204=1,532
According to this, the answer is that Sally has 1,532 stickers remaining.
if (3x_25)⁰ and( x+15⁰) are complemantary angles find the angles. pls answer fast my friend I will mark brainly
Answers
Answer:
50 degrees, 40 degrees
Step-by-step explanation:
3x-25+x+15=90 Complementary angles add up to 90 degrees
4x-10=90
4x=100
x=25
75-25=50 and 25 plus 15=40 50+40=90
x=25°
Further explanationThere are two angles that can form:
• Supplementary Angles: if both angles are added = 180 °
• Complementary Angles: if both angles are added = 90 °
(3x-25)+((x+15)=90
4x-10=90
4x=100
x=25°

What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are equal, and we also know that sum of all the interior angles of a triangle is equal to 180°.
∴ 47° + (2x + 13)° + (5y - 23)° = 180°.
47° + 13° - 23° + 2x + 5y = 180°.
2x + 5y = 143°...(i).
Now, We also know that when parallel lines are intersected by a transversal pair of alternate angles are equal and the sum of two adjacent angles is equal to 180°.
∴ 3x + (5y - 23)° = 180°.
3x + 5y = 157°...(ii)
Now subtracting eqn(i) from eqn(ii) we get x = 14°, and substituting the value of x in any of the equations we y = 23°.

We need to solve for d the number of days he worked and to do this we need to get d by itself

Here are a few fun facts:
A 19th century horse named 'Old Billy' is said to have lived 62 years.
Horses can sleep both lying down and standing up.
Horses can run shortly after birth.
Horses have around 205 bones in their skeleton.
Horses have been domesticated for over 5000 years.
Horses use their ears, eyes and nostrils to express their mood.
Because horse’s eyes are on the side of their head they are capable of seeing nearly 360 degrees at one time.
The fastest recorded sprinting speed of a horse was 88 kph (55 mph). Most gallop at around 44 kph or 27 mph.
The Przewalski’s horse is the only truly wild horse species still in existence. The only wild population is in Mongolia. There are however numerous populations across the world of feral horses e.g. mustangs in North America.

x/7 +13/14 = 17/14
double the first one so all the denominators are the same
2x/14+13/14=17/14
then subtract the second fraction from the thrid
2x/14=4/14
then we can divide by two so we are back to 7 as the demoninator
x/7=2/7
Convert the mix fraction into improper fraction:
(14 x 1) + 3 = 17 /14
X has to equal the difference between 13 and 17 which is 4
Remember since the lowest common denominator is 14 you would have to multiply x/7 by 2 on top and bottom and make sure that the x value is equal to 4
So ...
(2/7) + (13/14)
(4/14) + (13/14)
Add the number and keep the denominator the same
= 17/14 or 1(3/14)
Therefore the missing number is 2.
I hope this doesn’t sound too confusing :)

Answers
Answer:
the number of unique versions of the Grand Touring bike is 56
Step-by-step explanation:
The computation of the number of unique versions of the Grand Touring bike is shown below:
Here there are 14 color choices
Now each color could be with or without phone mount so it would be
= 14 × 2
= 28
And, each model could be sidecar or without sidecar so it would be
= 28 × 2
= 56
Hence, the number of unique versions of the Grand Touring bike is 56
