Mathematics

The slope is the same as the gradient

y=mx+c where m is the gradient and c is the y intercept
y=-5x-9

Therefore the 'slope' is -5 i.e. it goes down 5 every 1 across.

Find the area of the composite figure in terms of the figure (use 3.14 for pi)​
svp [43]

Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

10\cdot8=80 ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is \pi r^2. The radius is 4, as the diameter is 8.

3.14\cdot4^2

3.14\cdot16

50.24\div2=25.12

Add 80 and 25.12:

80+25.12=105.12

Hope this helped!

The t value for a 99% confidence interval estimation based upon a sample of size 10 is
Aliun [14]
Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.

Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as
(\Bar{x}- t\frac{s}{\sqrt{n}} , \, \Bar{x}+ t\frac{s}{\sqrt{n}}
where
 \Bar{x} = sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n =  sample size.

When reading the t-value, (n-1) is called the df or degrees of freedom.
