Answer:

816

A=a+b/ 2  h=13+38 /2·32=816

Answer:

The area is 816 [tex]m^2[/tex]

Step-by-step explanation:

The formula for the area of a trapezoid is

A= [tex]\frac{a+b}{2}[/tex]h

A and B are the bases and h stands for the height

So, then you can input all of your known variables

A= [tex]\frac{38 +13}{2}[/tex](32) ( honestly, you could just input all of this into a calculator)

A= [tex]\frac{51}{2}[/tex](32)

A= 816

I hope this helps :)

Complete question :

The average daily volume of a computer stock in 2011 was p = 35.1 million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of 40 trading days in 2014, he finds the sample mean to be 30.9 million shares, with a standard deviation of s = 11.8 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parts (a) through (c) below. State the hypotheses for the test. Construct a 95% confidence interval about the sample mean of stocks traded in 2014.

Answer:

H0 : μ = 35.1 ;

H1 : μ < 35.1 ;

(26.488 ; 35.312)

Step-by-step explanation:

The hypothesis :

H0 : μ = 35.1

H1 : μ < 35.1

The confidence interval :

Xbar ± Margin of error

Xbar = 30.9

Margin of Error = Zcritical * s/sqrt(n)

Zcritical at 95% = 1.96

Margin of Error = 1.96 * (11.8/sqrt(40))

Margin of Error = 4.412

Lower boundary :

30.9 - 4.412 = 26.488

Upper boundary :

30.9 + 4.412 = 35.312

Confidence interval = (26.488 ; 35.312)

Since the population mean value exists within the interval, the we fail to reject the Null.

Answer:

12<x<26

Step-by-step explanation:

7 + 19 = 26

19 - 7 = 12

Always put the larger number before the smaller one while subtracting like I just did.

The inequality to represent the range of lengths for the third side as

{x} < 26.

A triangle is a two - dimensional figure with three sides and three angles.

The sum of the angles of the triangle is equal to 180 degrees.

∠A + ∠B + ∠C = 180°

Given is that two sides of a triangle measure 7 feet and 19 feet.

It is aske to write an inequality to represent the range of lengths for the third side. It is given that two sides of a triangle measure 7 feet and 19 feet.

For a inequality, the sum of the lengths of the two smaller sides is greater than the length of the maximum side. So, write an inequality to represent the range of lengths for the third side as -

19 + 7 > x

x < 19 + 7

x < 26

So, we can conclude that the inequality to represent the range of lengths for the third side as {x} < 26.

Therefore, the inequality to represent the range of lengths for the third side as {x} < 26.

Answer

96

Step-by-step explanation:

Answer:

96m

Step-by-step explanation:

Surface area of a pyramids formula is SA= B+1/2*l*P

B= area of base

l= slant height

P= perimeter of base

B= 6*6= 36

l= 5

P= 6+6+6+6 = 12+12 = 24

plug them into the formula

SA= (36)+1/2 * (5)*(24)

SA = (36)+1/2* 120       ------------- do 5 * 24

SA= (36) + 60        -----------do 120/2

SA = 96

[tex]b = \sqrt{ \frac{ {c}^{2} }{2 {\pi}^{2} } - {a}^{2} } [/tex]

Answer:

8 in.

Step-by-step explanation:

The ratio of the surface areas is equal to the square of the ratio of the heights

Let h = the height of the smaller dodecagonal pyramid

So,  [tex]\frac{2080}{130} = \frac{32^{2}}{h^{2} }[/tex]

[tex]h^{2} = \frac{32^{2} * 130 }{2080}[/tex]

[tex]h^{2} = 64[/tex]

h = 8 in.

Answer:

11 breads

Step-by-step explanation:

Note that:

1 bread recipe = 1 bread

From the above question, we know that:

2/3 cups of walnut = 1 bread

7 1/2 cups of walnut = x breads

Cross Multiply

2/3 cups × x breads = 7 1/2 cups × 1 bread

x breads = 7 1/2 cups × 1 bread/2/3 cups

x breads = 7 1/2 ÷ 2/3

x breads = 15/2 ÷ 2/3

x breads = 15/2 × 3/2

x breads = 45/4

x breads = 11 1/4 breads

Maximum full recipe = 11 breads.

Therefore, the MAXIMUM numbers of full recipe of walnut bread the baker can make is 11 breads.

Step-by-step explanation:

The single expression that represents the surface area of the rectangular prism is :

S= 2lw + 2lh + 2wh

Let us assume the l is length, width is w and h is the height of the rectangular prism.

What is the rectangular prism?

In geometry, a rectangular prism can be stated as a 3-dimensional solid shape that has 6 faces with its base as rectangles.

So, the surface area S would be :

S = surface area

S= 2lw + 2lh + 2wh

where,

l= length

w= width

h = height

Therefore, the surface area of the rectangular prism is :

S= 2lw + 2lh + 2wh

Answer:

x= 16/3

Step-by-step explanation:

From the equation we know x is the same for all sides so the perimeter is:

p = x + x+ x   we know the perimeter so it would be

16 = 3x  (we add the x)

then we need to divide both sides by three to have an equation for x so it would be:

x= 16/3
