*assuming that ABC is a straight line** 
<span>then you have </span>
<span>AB = 17.89 ..... this is the length of the whole line </span>

<span>BC is a part of the line = 7 </span>

<span>therefore the length of the other part = 17.89 - 7 </span>

<span>= 10.89</span>

17.89-7=10.89
You know that the distance from A to b is 17.89 and the distance from b to c is 7.  So the length from a to c is the whole distance(a to b) subtracted by a portion of the distance(b to c) giving us 10.89

What is... X/2 - 13 = 1
kow [346]
X ÷ 2 - 13 = 1
Write the division as a fraction
\frac{1}{2}x - 13 = 1
Multiple both sides of the equation by 2
2 \times  \frac{1}{2}x  \times  - 2 \times 13 = 12
Reduce the number with greatest common divisor 2
x - 2 \times 3 = 2
Multiply the numbers
- 2 \times 13
Then u will have
x - 26 = 2
Move constant to the right by adding its opposite sides
x - 26 + 26 = 2 + 26
Eliminate the opposites
- 26 + 26
Then you have
x = 2 + 26
Add the numbers
x = 28

What is the volume of the sphere given below? if necessary, round your answer to two decimal places.
Marrrta [24]
The formula for volume of a sphere is V=(4pi*r^3)/3.
Plugging in 12 for r we get
V=(4pi*(12)^3)/3
V=(4pi*1728)/3
V=(6912pi)/3
V=2304pi
Round to 2 decimal places: 7238.23
Final Answer:
7238.23 cubic units.

A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66
Angelina_Jolie [31]

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
