<h2>Answer:</h2>

Isosceles and right triangles are the right answers.

Step-by-step explanation:

In the given triangle ABC, we can see that it is a right angle triangle. Angle C is 90 degrees. So, it is a right angle triangle.

Also two sides, BC and AC are 3 inches, means they are same. So, it is an isosceles triangle. The definition of isosceles triangle is that it has 2 sides equal in length.

The third option is acute triangle. This is wrong as acute triangle has all the three angles less than 90 degrees.

It has a right angle (90 degrees) and 2 sides are equal which makes it isosceles.
So there's only one choice left.

stira [4]

Answer:

The 't' test statistic = 1.46 < 1.69

The test of hypothesis is H 0 :μ = 800 is accepted

A sample of 30 bulbs are found came from average µ= 800

Step-by-step explanation:

Step 1:-

Given population of mean μ = 800

given size of small sample n =30

sample standard deviation 'S' = 45

Mean value of the sample χ = 788

Null hypothesis H_{0} =µ  =800

alternative hypothesis  H_{1} = µ ≠ 800

<u>Step 2</u>:-

The 't' test statistic t =  \frac{x-μ}{\frac{sig}{\sqrt{n} } }

                             t = \frac{788-800}{\frac{45}{\sqrt{30} } }

                       t = \frac{12}{8.215} = 1.4607

<u>Step 3</u>:-

The degrees of freedom γ = n-1 = 30-1 =29

From "t" value from table at 0.05 level of significance ( t = 1.69)

The calculated value t = 1.4607 < 1.69

Therefore The null hypothesis H_{0} ' is accepted.

<u>conclusion</u>:-

A sample of 30 bulbs are came found from average µ= 800

If f(x) = 6x +5 and g(x) = 2x – 7 find (fºg)(x)
adell [148]

Answer:

f(g(x)) = 12x - 37

Step-by-step explanation:

Step 1: Define

f(x) = 6x + 5

g(x) = 2x - 7

Step 2: Find f(g(x))

f(g(x)) = 6(2x - 7) + 5

f(g(x)) = 12x - 42 + 5

f(g(x)) = 12x - 37
