Step-by-step explanation:

Area of trapezium = 1/2 (a + b)h

a = 6 ft , b = 9 ft , h = 4 ft

Area = 1/2 (6 + 9) 4

= 30 ft²

Suppose the scores on an exam are normally distributed with a mean μ = 75 points, and standard deviation σ = 8 points. Suppose t
alexandr402 [8]

Answer:

89.008

Step-by-step explanation:

z = (x– mean)/ standard deviation

x = z * standard deviation + mean

Now, z value for the top 4% of the exams (which is the same as getting a score below the 96%) has to be found using a z table.

In this case z = 1.751

x = 1.751 * 8 + 75

x = 89.008

The area of the base of a cone is 16, and the height is 10. Find the area of a cross-section that is distance 5 from the vertex.
zubka84 [21]

Answer: Area of cross section would be 4 square units.

Step-by-step explanation:

Since we have given that

Area of base of cone = 16 sq. units

Height = 10

We need to find the area of cross section that is distance 5 from the vertex.

So, Height of cross section = 5 units

total height of cone = 10

It means the cross section is half of the whole cone.

So, it becomes,

(\dfrac{1}{2})^2=\dfrac{A}{16}\\\\\dfrac{1}{4}=\dfrac{A}{16}\\\\16=4A\\\\\dfrac{16}{4}=A\\\\4=A

Hence, Area of cross section would be 4 square units.

The figure below is a rhombus. What does Y equal?
Luba_88 [7]

Given data:

The angle of the rhomes = 124 degrees.

Subject: Calculate the value of Y.

We know the opposite angle of the rhombus are equal.

in triangle ABC,

sum of three angle = 180 degrees.

Angle DCA = angle CAB

Angle BCA = angle CAD,

Angle D = angle B,

\begin{gathered} \angle DCA=\angle CAB \\ \angle BCA=\angle CAD \\ \angle D=\angle B=124^{\circ} \end{gathered}

Now, We know that the sum of the interior angle of rhombus is equal to 360 degrees.

I am sorry, but I won't be able to help you with that questions because it is out of the scope of Brainly Tutor. Perhaps you would like to post it on Brainly.in?

Alexa says that the pattern with the expression 5n+3 will not contain the term 82. Is she right? Explain your answer.
kolbaska11 [484]

Answer:

correct

Step-by-step explanation:

She is correct.

For any integer, n, 5n is a multiple of 5.

5n + 3 is 3 more than a multiple of 5.

Start with 82. Subtract 3. Now you have 79.

79 is not a multiple of 5, so 5n + 3 will not contain the term 82.
