Mateo has already swum Four-fifths of the 2,000 meters he is swimming today. If he continues swimming at a pace of Three-fourths of a meter per second, which expression shows the amount of time it will take him to swim the remaining distance? A. 2000 times four-fifths times three-fourths B. 2000 times four-fifths divided by three-fourths C. 2000 times one-fifth times three-fourths D. 2000 times one-fifth divided by three-fourths
Answer:
D
Step-by-step explanation:
The amount of time that will take him to swim the remaining distance will be [2,000 (1/5)] / (3/4). Then the correct option is D.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
Mateo has proactively swum Four-fifths of the 2,000 meters he is swimming today. On the off chance that he keeps swimming at a speed of Three-fourths of a meter each second.
3/4 = 2,000 (1 - 4/5) / T
T = [2,000 (1/5)] / (3/4)
The amount of time that will take him to swim the remaining distance will be [2,000 (1/5)] / (3/4). Then the correct option is D.

Answer:
1. 230, 219, 208, 197, 186.
2. Arithmetic, you are subtracting a constant rate, instead of an exponential rate.
3. Finite, the question says the farmer only took 10 trips, infinite would be much, much much more trips.
Step-by-step explanation:
1. The pattern is to subtract 11, so you just do this for 3 more times.
2. Geometric sequences could look something like 230-11=219. The you multiply by a random number like 2, then you subtract 219- (11x2), 219-22=197. This sequence does not do that.
3. It says in the question the farmer only does it for 10 more times.

Mr. Henderson's imaginary) Porsche accelerates from 20 m/s to 60 m/s in 4 seconds. Its acceleration is
Answer:
[tex]a = 10[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Velocity\ (u) = 20m/s[/tex]
[tex]Final\ Velocity\ (v) = 60m/s[/tex]
[tex]Time = 4s[/tex]
Required
Determine the acceleration
This question will be answered using the first equation of motion.
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]60 = 20 + 4 * a[/tex]
[tex]60 = 20 + 4 a[/tex]
Subtract 20 from both sides
[tex]60 - 20= 20 -20 + 4 a[/tex]
[tex]40= 4 a[/tex]
Divide both sides by 4
[tex]10 = a[/tex]
[tex]a = 10[/tex]
Hence, the acceleration is 10m/s/s

According to a college survey, 22% of all students work full time. Find the standard deviation for the random variable X, the number of students who work full time in samples of size 16.
Answer:
1.66
Step-by-step explanation:
Calculation to find the standard deviation for the random variable X of the number of students who work full time in samples of size
Using this formula
Standard deviation(X)=√np(1−p)
Where,
n represent the number of students=16
p represent the percentage of all students who work full time=22
Let plug in the formula
Standard deviation(X)=√16(0.22)(1−0.22)
Standard deviation(X)=√(3.52)(0.78)
Standard deviation(X)=√2.7456
Standard deviation(X)=1.656
Standard deviation(X)=1.66 (Approximately)
Therefore the standard deviation for the number of students who work full time in samples of size 16 will be 1.66

In Jayce's favorite video game, he collects stars to earn points. Today, he collected 80 silver stars and earned 160 points. He also collected 30 gold stars and earned 150 points. How many more points per star does Jayce earn from gold stars?
Jayce earns 3 more points from gold stars than from silver stars.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Jayce collected 80 silver stars and earned 160 points.
He collected 30 gold stars and earned 150 points.
Therefore,
The points per star Jayce earns from silver stars
160/80=2,
The points per star Jayce earns from gold stars
150/30=5
Hence, Jayce earns 3 more points from gold stars than silver stars.

x = 120
Which mistake did Javier make in his calculations?
Answer:
8 should be multiplied in the parenthesis
Step-by-step explanation:
8(9 + x) = 192
72 + 8x = 192
8x = 120
x = 4
Javier made the mistake while expanding the brackets.
What is the order of operation?Order of operation means simplify the function , expression etc. in given manner.
To expand a single bracket multiply each term inside the bracket by the term outside the bracket.
8 (9+x) = 192
8*9 + 8*x = 192
72 + 8x = 192
Now, rearranging the above expression
8x = 192 - 72
8x = 120
x = 120/ 8
x = 5

Step-by-step explanation:
What does A and B equal?? Helpppp???
Answer:
I believe that the answers are:
a= 65 degrees
b= 80 degrees
Step-by-step explanation:
Purple 80 and b should be the same so 80 degrees
180 - 80 is 100 which is A so a equals 100-35 whis is 65.
Answer:
a=65°, b=100°
Step-by-step explanation:
Hope the answers help! I got confused at first, but take a last look at line BE. Angle EAF is vertically opposite to this line. This means that angle BAF equals 80°. b=100°. a is just 180-80-35, so a=65°.

A Ferris Wheel is set up at the carnival it has a diameter of 45 feet. What is the total circumference if the ferris wheel makes 4 rotations around?
Answer:
The circumference is 565.2 feet when the ferris wheel makes 4 rotations.
Step-by-step explanation:
Given that the diameter of the wheel is 45 feet.
That is:
[tex]d = 45\ feet[/tex]
We have to find the radius first
[tex]r = \frac{d}{2} = \frac{45}{2} = 22.5\ feet[/tex]
The circumference of the circular wheel for one rotation will be:
[tex]C = 2\pi r[/tex]
And for four rotations' circumference the circumference of one rotation will be multiplied with 4.
[tex]C = 2 * 3.14 * 22.5\\C = 141.3\ feet[/tex]
Total circumference:
[tex]C_T = 4C\\= 4 * 141.3\\=565.2\ feet[/tex]
Hence,
The circumference is 565.2 feet when the ferris wheel makes 4 rotations.
If the null hypothesis is inside the confidence interval, then the decision was likely to ________ using hypothesis testing.
a) reject the null hypothesis
b) retain the null hypothesis
Answer:
B: Retain the null hypothesis
Step-by-step explanation:
In the relationship between the confidence interval and hypothesis, it is stated that:
When the confidence interval is constructed, all values that fall inside the interval are considered possible values for the parameter that we are estimating while values that fall outside the interval are rejected as they are considered not possible or realistic values.
Now, If the value of the parameter specified by the null hypothesis falls inside the given confidence interval, then we will fail to reject the null hypothesis at the corresponding significance level. However, If the value specified by the null hypothesis doesn't fall inside the given confidence interval, then the null hypothesis can be rejected at the corresponding significance level.
