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:

[-4, infinity)

Step-by-step explanation:

The range is all the y values. The minimum is -4, and the maximum is infinity because there are arrows pointing upwards.

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

Answer:

B.

Step-by-step explanation:

An intercepted arc can therefore be defined as an arc formed when one or two different chords or line segments cut across a circle and meet at a common point called a vertex.

The required intercepted arc has been shown in circle B. Option D is the correct answer.

In geometry, an intercepted arc is an arc of a circle that lies in the interior of an inscribed angle of the circle, and whose endpoints lie on the sides of the angle.

In other words, if we draw two rays originating from a point on the circle's circumference, the intercepted arc is part of the circle's circumference that lies between the two rays and is located inside the angle formed by the rays.

Here,

Following the above definition, Circle B consists of the intercepted arc.

Answer:

6b + 3a - 39n

Step-by-step explanation:

Expanding using the distributive property :

-3(-2b + 5a + 7n - 10a + 6n +4a)

Multiply all values in the bracket by - 3

6b -15a - 21n + 30a - 18n - 12a

Collect like terms

6b - 15a + 30a - 12a - 21n - 18n

6b + 3a - 39n

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:

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.

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
