Answer:

They will cross the finish line together in 175 minutes.

Step-by-step explanation:

This question asks you to consider the 25 and 35 times table.

I listed the 25 and 35 times tables and tried to find the lowest common multiple.

You can see that on Josephs' 7th lap of the track he will cross the line simulatneously with Owuor who will be on his 5th lap.  So the answer should be 175 minutes.

25 × 1 = 25   35 × 1 = 35

25 × 2 = 50   35 × 2 = 70

25 × 3 = 75       35 × 3 = 105  

25 × 4 = 100   35 × 4 = 140

25 × 5 = 125   35 × 5 = 175

25 × 6 = 150     35 × 6 = 210

25 × 7 = 175

25 × 8 = 200

Answer:

Point B: (-8,2)  Point C: (-8,9)  Point D: (-5,4)

Step-by-step explanation:

Since you are reflecting over the y-axis, the numbers in the coordinates will be the same but they will all have a negative "x" value instead of both numbers in the coordinate being positive.

Point B: (8,2) -->  (-8,2)

Point C: (8,9) -->  (-8,9)

Point D: (5,4) -->  (-5,4)

Answer:

[tex]\sqrt[3]{64}[/tex] < [tex]\sqrt[3]{81}[/tex] < [tex]\sqrt[3]{125}[/tex] , that is

4 < [tex]\sqrt[3]{81}[/tex] < 5

Answer:

mPS = 80°

Step-by-step explanation:

angles on a circle subtended by the same arc are congruent

∠ PQS and ∠ PRS are both subtended by arc PS , then

10 + 3x = 110 - 7x ( add 7x to both sides )

10 + 10x = 110 ( subtract 10 from both sides )

10x = 100 ( divide both sides by 10 )

x = 10

then

∠ PQS = 110 - 7x = 110 - 7(10) = 110 - 70 = 40°

the inscribed angle PQS is half the measure of its intercepted arc PS , then

PS = 2 × 40° = 80°

Range of temperatures does the average rate of change in temperature fall -13F and 9 F

The Fahrenheit temperature scale is used in the United States; the Celsius, or centigrade, scale is employed in most other countries and for scientific purposes worldwide. The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) representation is: °F = (9/5 × °C) + 32.

Given function:

f(x)= -11 sin(7/3 x+ 1/6) -2

The function will be maximum at

7/3 x +1/6= 3π/2

So, the maximum temperature will be

= -11 sin (3π/2) -2

= 11 -2

=9 F

The function will be minimum at

7/3 x +1/6= π/2

So, the maximum temperature will be

= -11 sin (π/2) -2

= -11 -2

= -13 F

Answer: 20.4

Step-by-step explanation:

Answer:

That would be 0.6 that means 60 percent.

Answer:

Probability of not spinning an even number is 0.6

Step-by-step explanation:

Total probability is 100 since it represented by %.

Therefore if 40% is the probability of spinning an even number then that of not spinning an even number is simply

100% - 40% = 60%

Expressing 60% as a decimal gives us 0.6

3421880 number of the different meals are possible.

The arrangement of the different things or numbers in the number of the ways is called as the combination.

It is given that:-

Number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts.

So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre,

so the number of possible meals to this point is

n = 7  x  10 = 70

Finally, you finish off with a dessert, so the number of meals is:

n = 70 x 4 = 280

Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is

n = 77 x  1010 x  44 = 3421880

Therefore 3421880 different meals are possible.

b = speed of the boat in still water

c = speed of the current

when going Upstream, the boat is not really going "b" fast, is really going slower, is going "b - c", because the current is subtracting speed from it, likewise, when going Downstream the boat is not going "b" fast, is really going faster, is going "b + c", because the current is adding its speed to it.

now, going either way the boat travelled the same 18 miles.

The measure of minor arc BC is equal to ∠BPC which is 147 degrees.

An equation is an expression that shows the relationship between two or more variables and numbers.

From the diagram:

4k + 159 = 2k + 153 (vertical opposite angles are equal)

4k + 159 = 2k + 153

k = -3

Arc Bc = 4k + 159 = 4(-3) + 159 = 147

The measure of minor arc BC is equal to ∠BPC which is 147 degrees.

Answer:

8 7/20

Step-by-step explanation:

Converting both numbers to improper fractions :

4 3/5

⇒ (4 x 5/5) + 3/5

⇒ 20/5 + 3/5

⇒ 23/5

-3 3/4

⇒ - (3 x 4/4 + 3/4)

⇒ - (12/4 + 3/4)

⇒  -15/4

Take the LCM as 20 and convert :

23/5

⇒ 23/5 x 4/4

⇒ 92/20

-15/4

⇒ -15/4 x 5/5

⇒ -75/20

Now find the difference :

⇒ 92/20 - (-75/20)

⇒ 92/20 + 75/20

⇒ 92 + 75 / 20

⇒ 167/20

Now convert into a mixed number :

⇒ 167/20

⇒ 8 7/20

The addition of the functions f(x) and g(x) will be ln (2x) + 3 sin(x) – 22. Then the correct option is C.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

The functions are given below.

f(x) = ln (2x) – 15

g(x) = 3 sin(x) – 7

Then the addition of the function will be

(f + g)(x) = f(x) + g(x)

(f + g)(x) = ln (2x) – 15 + 3 sin(x) – 7

(f + g)(x) = ln (2x) + 3 sin(x) – 22

Then the correct option is C.

A strategy which would produce a new confidence interval with an increased margin of error is to: A. use a 98% confidence level.

A confidence interval simply refers to a range of estimated values which defines the probability that a population parameter will lie within it.

Mathematically, a margin of error is calculated by using this formula:

[tex]MOE_{\gamma}=Z_{\gamma} \times \sqrt{\frac{\sigma^2}{n} }[/tex]

From the above formula, we can deduce that the margin of error is directly proportional to the critical value and inversely proportional to the square root of sample size.

This ultimately implies that, increasing the confidence level from 95% to 98% would increase the critical value and by extension the margin of error and vice-versa.
