The average a of two numbers c and d is equal to half the sum of c and d

Answers

Answer 1

Answer:

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

Step-by-step explanation:

Required

Write the given statement as an equation

To start with, we solve for the average of c and d

[tex]Average = \frac{\sum x}{n}[/tex]

[tex]Average = \frac{c + d}{2}[/tex]

Next, is to determine half sum

[tex]Half\ sum = \frac{c + d}{2}[/tex]

Since both are equal; we have"

[tex]\frac{c + d}{2}= \frac{c + d}{2}[/tex]

The above shows that the statement is true

Answer:

hello some parts of your question is missing below is the complete question

Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.25 probability that a pea has green pods. Assume that the offspring peas are randomly selected in groups of 36

.a. Find the mean and the standard deviation for the numbers of peas with green pods in the groups of 36

The value of the mean is

μ=___ peas.

The value of the standard deviation is

σ=___peas.

b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.

Values of ___ peas or fewer are significantly low.

Values of ___ peas or greater are significantly high.

c. Is a result of 2 peas with green pods a result that is significantly low? Why or why not?

The result (is, is not) significantly low, because 2 peas with green pods is (greater than, equal to, less than) peas.

Answer : A) mean : 9,  std = 2.6

               B) significantly low value : = 3.8, significantly high value = 14.2

C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods

Step-by-step explanation:

given data :

probability ( p )= 0.25

number of groups ( n )= 36

A ) i) Mean of the of the peas ( u )

u = np = 36 * 0.25 = 9

ii) standard deviation of the peas ( б ) = [tex]\sqrt{np(1-p)} = \sqrt{9(1-0.25)}[/tex]  = 2.60

B) Using the range rule of thumb to find the values separating results that are significantly low or significantly high.

note : assuming z = 2 and error = 5%

i) The values that are significantly lower

u - zб = 9 - (2*2.6 )

         = 3.8

ii) The values that are significantly higher

u + zб = 9 + (2*2.6)

          = 14.2

C ) From the significant low value it can be observed that the result is very low because 2 peas with green pods < 3.8 peas with green pods

if 5x-7=13, what is the value of 10x-14

Answers

Answer:

10x-14=26

Step-by-step explanation:

x = 4

10 x 4 = 40

40 - 14 = 26

Answer:

26

Step-by-step explanation:

In order to answer this question, we must first find what x equals, so we need to solve for x in the equation 5x - 7 = 13:

5x - 7 = 13

     +7   +7

5x = 20

/5     /5

x = 4

Now, we plug in 4 for 'x' in the equation 10x - 14:

10(4) - 14 =

40 - 14 =

26

So, 10(4) - 14 = 26

Hope this helps :)

Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda to make a batch of cookies. Which proportion could be solved to find X, the number of teaspoons of baking soda needed for 9 cups of sugar?

Answers

Answer:

Heres how to solve.

Step-by-step explanation:

3 cups of sugar for every 2 teaspoons of baking soda.

So 6 cups of sugar for 4 teaspoons of baking soda.

And 9 cups of sugar for 6 teaspoons of baking soda.

Basically you just multiply by 3, 3×3=9 and 2*3=6

The number of teaspoons of baking soda Trisha needed will be 6.

It is given that Trisha uses 3 cups of sugar for every 2 teaspoon of baking soda.

We have to find out that what will be the number of teaspoons of baking soda needed for 9 cups of sugar.

If a car goes 10 km in two hours , how far will it go in one hour ?

The car will go, 10 ÷ 2 = 5 km in an hour.

As Trisha uses 3 cups of sugar for every 2 teaspoons of baking soda.

For 1 cup of sugar Trisha will have to use 2/3 teaspoons of baking soda .

For 9 cup of sugar Trisha will use ;

= (2/3) × 9 = 18 ÷ 3

= 6

So, Trisha will have to use 6 teaspoons of baking soda for 9 cups of sugar.

As CD⊥AB, ∠BDC = ∠ADC = 90°

∠BDC ≅ ∠ADC

∠BCD = 180 - (∠BDC + ∠DBC)

and

∠ACD = 180 - (∠ADC + ∠DAC)

We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC

Then we get same equation for ∠BCD and ∠ACD

Step-by-step explanation:

See the attached picture for a drawing of the angle and its terminal point coordinates. Those are (cos(4π/3), sin(4π/3)), so we have the following trig function values:

  sin(4π/3) = -√3/2

  cos(4π/3) = -1/2

  tan(4π/3) = sin/cos = √3
