round 23.2736 to the nearest thousandth
Answer:
23.274
Step-by-step explanation:
Here, rounding to the nearest thousandth means rounding to the nearest 0.001.
Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.
Hope this helped!
The required round-off of the number 23.2736 is 23.274.
To determine the round of the number 23.2736 to the nearest thousandth.
The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.
Here,
The given number 23.2736,
The number next to the thousandth place is 6 which is greater than 5 than the number 6 can be pushed to 10 and the number 1 will be added to the number in the thousandth place which is 3.
So the required round-off would be given as 23.234.
Thus, the required round-off of the number 23.2736 is 23.274.

In a certain fraction, the denominator is less 7 than the numerator. If 3 is added to both the numerator and denominator, the resulting fraction is equal to 15/8
. Find the original fraction.
Answer:
original fraction =12/5
Step-by-step explanation:
let x = numerator
therefore
x+3/x-7+3 =15/8
x+3/x-4 =15/8
8(x+3)=15(x-4)
8x+24=15x-60
84=7x
84/7=x
12=x
therefore original fraction = 12/5

What is the value of tan c
Answer:
In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735.
Describe the sampling distribution of Phat. Assume the size of the Population is 25,000. N = 500 P = 0.4 Determine the Mean of the sampling distribution of Phat. Determine the standard deviation of the sampling distribution of Phat.
Answer:
0.022
Step-by-step explanation:
Given that :
Population size = 25000
n = 500 ; p = 0.4
Size of random sample (n) = 500
5% of population size : 0.05 * 25000 = 1250
Distribution is normally distributed since n < 5% of population size
Hence, the mean of the distribution = p = 0.4
Standard deviation = √((pq) /n)
q = 1 - p ; q = 1 - 0. 4 = 0.6
Standard deviation = √((0.4 * 0.6) /500)
Standard deviation = 0.0219089
= 0.022

A bike path is 3 miles long. there are distance markers every path one fourth mile to the end of the path. which number line correctly models this situation and the total number of distance markers?
Given :
A bike path is 3 miles long. there are distance markers every path one fourth mile to the end of the path.
To Find :
Which number line correctly models this situation and the total number of distance markers.
Solution :
It is given that their are markers every 1/4 part of mile.
So, their are 4 markers per mile.
Numbers of markers in 3 miles long path is :
[tex]n = 3\times 4\\\\n = 12[/tex]
Therefore, the total number of distance markers in 3 mile path is 12.
Hence, this is the required solution.

To solve for the lengths of the right triangle sides, which equation is correct?
A. x² = (4x - 1)² + (6x + 7)?
B. x2 +(6x + 7)2 = (4x - 1)2
c. x² = (4x - 1)² – (6x + 772
D.x² + (4x - 1)2 = (6x + 7)?
4x-1
To solve for the lengths of the right triangle sides, equation is correct.
(Type A, B, C, or D.)
Answer:
A. [tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]
Step-by-step explanation:
The question seems to be incomplete. However, we'll make the following assumption.
[tex]Opposite = 6x + 7[/tex]
[tex]Adjacent = 4x - 1[/tex]
[tex]Hypothenuse = x[/tex]
Pythagoras theorem states that:
[tex]Hypothenuse^2 = Opposite^2 + Adjacent^2[/tex]
Substitute values for Hypothenuse, Opposite and Adjacent.
This gives
[tex]x^2 = (6x + 7)^2 + (4x - 1)^2[/tex]
or
[tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]

An office building has 66000 of net income and sold for 550000. What is the rate of return
Answer:
The rate of return will be: 12%
Step-by-step explanation:
Given
Net income = 66000As the building was sold for 550000
Market value = 550,000Return can be calculated by dividing the market value by the net income using the formula
Return = Net income / Market value
= 66000 / 550,000
= 0.12 which is 12%
Therefore, the rate of return will be: 12%

Suppose a box contains 10 coins, where three of them are type-A and seven of them are type-B. The probability of head is 0.4 if we toss a type-A coin and 0.6 for a type-B coin. One person chooses one coin at random and tosses it three times. What is the probability that this coin is type-A if the outcome is two heads out of three tosses?
Answer:
0.222
Step-by-step explanation:
Given that:
For Type A coins = 3
The probability of head in a type A coin i.e. (p) = 0.4
Then, the probability of getting a tail (q) = 1 - p = 1 - 0.4 = 0.6
For Type B coins = 7
The probability of head in a type B coin i.e. (p) = 0.6
Then, the probability of getting a tail (q) = 1 - p = 1 - 0.6 = 0.4
One person who tosses a coin three times get a probability of obtaining a head twice.
Using, the formula:
=[tex]^nC_r \times p^r \times q^{n-r}[/tex]
For Type A coin;
The probability of getting two heads in three tosses is:
[tex]= ^3C_2 \times 0.4^2 \times 0.6^{1}[/tex]
[tex]=\dfrac{3!}{2!(3-2)!} \times 0.4^2 \times 0.6^1[/tex]
= 0.288
For Type B coin;
The probability of getting two heads in three tosses is:
[tex]= ^3C_2 \times 0.6^2 \times 0.4^{1}[/tex]
[tex]=\dfrac{3!}{2!(3-2)!} \times 0.6^2 \times 0.4^1[/tex]
= 0.432
Since we have two heads out of three tosses, the probability that the coin is type A is = (P) of choosing coin A × (P) of obtaining two heads from three tosses) / total probability of getting two heads from three tosses.
However;
(P) of choosing coin A = 3/10 = 0.3
(P) of choosing coin B = 7/10 = 0.7
∴
Given that, we obtain two head from three tosses, the (P) that the coin type is A is:
[tex]= \dfrac{(0.3 \times 0.288)}{ (0.3 \times 0.288 + 0.7 \times 0.432)}[/tex]
[tex]= \dfrac{(0.0864)}{ (0.0864 + 0.3024)}[/tex]
= 0.222
Which equation has the same solution as 4-2(x-5)=x-19

Which expression would be easier to simplify if you used the associative property to change the grouping?
A. 85 + (120 + 80)
B. [-40 + (60)] + 52
C. (2 + 3/7) + 4/7
D. 4 + (1.2 + (-0.2))
Answer:
C
Step-by-step explanation:
In A and B, the numbers involved in expressions are integers.
Hence, they can be easily added or subtracted.
In C, the numbers involved in expression are fractions which are not grouped together.
They can be added but by using associative property, it becomes much more easier.
That is, grouping fractions.

Cleo and her family fished for 3 days and caught 100 fish between them. They caught 12 fish on day 2 and 16 fish on day 3. How many fish did they catch on the first day.
Which equation is correct.
12x + 16 = 100
12x + 16 = 100
x + 12 + 16 = 100
x + 12 + 16 = 100
16x + 12 = 100
Answer:
x + 12 + 16 = 100
72 fishes
Step-by-step explanation:
Given parameters:
Number of days fished = 3days
Number of fishes caught = 100 fishes
Number of fish caught on day 2 = 12fishes
Number of fish caught on day 3 = 16fishes
Unknown:
Number of fish caught on the first day = ?
Solution:
Let the number of fishes caught on the first day = x;
Total number of fishes caught = No of fish on day 1 + No of fish on day 2 + number of fish on day 3
Insert the parameters and solve;
100 = x + 12 + 16
x = 100 - 28 = 72fishes
