i. Predicted chi-square value(x^2)?______ 22.35

ii.  df_______ 6-1= 5

iii. Using the critical values table, determine the predicted P value

The P-Value is .050985 for 5 df and 0.05 significance level. The result is not significant at p < .01.

The P-Value is .010362 for 5 df and 0.01 significance level. The result is not significant at p < .01.

Step-by-step explanation:

Phenotype     Predicted ( o)       Expected (e)           (o-e)          (o-e)²/e

                       (observed)

A- normal         19                 3/4 * (1/4)= 3/16  25.5      -6.5           1.66

O  normal         5                  1/4 * (1/4)= 1/16     8.5        -3.5            1.44

A trait               70                 3/4 * (1/2)= 3/8     51          19               7.07

O  trait               25                1/4 * (1/2)= 1/8      17            8              3.67

A  Disease        13               3/4 * (1/4)= 3/16    25.5      -12.5           6.13

O  Disease       4                 1/4 * (1/4)= 1/16        8.5     -4.5             2.38

                       136                                              136                         22.35

i. What is your predicted chi-square value(x^2)?______ 22.35

ii. Calculate df_______ 6-1= 5

iii. Using the critical values table, determine the predicted P value

The critical region for alpha =0.05 is χ² ≥ χ² (0.05,5) = 11.02

The P-Value is .050985. The result is not significant at p < .01.

The critical region for alpha =0.01 is χ² ≥ χ² (0.01,5) = 15.00

The P-Value is .010362. The result is not significant at p < .01.

The calculated value of chi square is  22.35  which is greater than  15.00  and 11.02 , the critical regions at alpha 0.05 and 0.01

Therefore it falls in the critical region and the result is insignificant.

This probability is represented with [tex]P(x = 1)[/tex]

From the table:

When x = 1; P(x) = 0.10

Hence:

[tex]P(x = 1) = 0.10[/tex]

In other words, the probability of selling exactly 1 is 0.10

[tex]Expression = x + 18x\%[/tex]

[tex]Expression = 1.18x[/tex]

Step-by-step explanation:

Given

Represent their goal with x

Additional = 18%

Required

Write two expressions to describe the total percentage

The expression is derived using:

[tex]Expression = Goal + Additional[/tex]

This gives:

[tex]Expression = x + 18\% * x[/tex]

[tex]Expression = x + 18x\%[/tex]

Solving further (Express percentage as decimal)

[tex]Expression = x + 0.18x[/tex]

[tex]Expression = 1.18x[/tex]

Answer:

x ≈ 2.4

Step-by-step explanation:

Area of the triangle = 1/2 absin theta

Find the diagram of the triangle attached

a = 2x-3

b =x+2

theta = 45°

Substitute and find x

4√2 = 1/2(2x-3)(x+2)sin45

8/√2 = (2x-3)(x+2)(1/√2)

8 = (2x-3)(x+2)

Expand

8 = 2x²+4x-3x-6

2x²+x-6-8=0

2x²+x-14 = 0

x = -1±√1²-4(14)(2)/2(2)

x = -1±√1+112/4

x = -1±√113/4

x = -1+10.63/4

x = 9.63/4

x = 2.4

The value of x is 3.075.

Given that,

The area of the triangle is [tex]4\sqrt{2}[/tex] square meter,

and [tex]\theta[/tex] is 45 degrees.

The one side of the triangle is (2x-3) and the other side of the triangle is (x+2).

We have to determine

The value of x.

According to the question

The area of the triangle is determined by the following formula,

[tex]\rm Area \ of \ triangle = \dfrac{1}{2} sin\theta[/tex]

Substitute all the values in the formula

[tex]\rm Area \ of \ triangle = \dfrac{1}{2} absin\theta\\\\4\sqrt{2} = \dfrac{1}{2} (2x-3)(x+2) sin45\\\\2\times4\sqrt{2} = (2x^2+4x-3x-6)\dfrac{1}{\sqrt{2} }\\\\\sqrt{2} \times8\sqrt{2} = (2x^2+x-6)\\\\8\times2 = (2x^2+x-6)\\\\16 = 2x^2+x-6\\\\2x^2+x-6-16=0\\\\2x^2+x-22=0\\\\x = \dfrac{-b\pm\sqrt{b^2-4ac} }{2a}\\\\x = \dfrac{-1\pm\sqrt{(-1)^2-4\times2\times(-22)} }{2\times2}\\\\x = \dfrac{-1\pm \sqrt{177} }{4}\\\\x = \dfrac{-`1\pm13.30 }{4}\\\\[/tex]

[tex]\rm x = \dfrac{-1+13.30}{4} \ and \ x = \dfrac{-1-13.30}{4} \\\\x = \dfrac{12.30}{4} \ and \ x= \dfrac{-14.30}{4}\\\\x = 3.075 \ and \ x = -3.575[/tex]

The value of x can not be negative so the value of x is 3.075.

Hence, The required value of x is 3.075.

Given

Without using a synthetic division, we can use easier method to find the quotient.

We know the formula:

Rewrite the given as:

This expression, when divided by (x - 1) leave the quotient (x² + x + 1) and a remainder of 2

The quotient of the equation is A = x³ + x + 1 + ( 2/x + 1 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the first equation be p = x³ + 1

Let the second equation be q = x - 1

A = p / q

On simplifying , we get

A = x³ + 1 / ( x - 1 )

On dividing , we get the quotient as

A = x² + ( x² + 1 ) / ( x - 1 )

A = x³ + x + 1 + ( 2/x + 1 )

Hence , the quotient is A = x³ + x + 1 + ( 2/x + 1 )

Answer:

The median is 6

Step-by-step explanation:

First put the numbers in order: 3,4,4,4,5,7,7,8,9,12

Here, the 5th & 6th terms are 5 &7

So, median = 5+7/2

=12/2

=6

Answer:

6

Step-by-step explanation:

For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,

The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,

=> Median = x₁ + x₂ / 2

=> Median = 5 + 7/2

=> Median = 12/2

=> Median = 6

D. 3:00 p.m.

Step-by-step explanation:

d = Distance = 320 miles

s = Speed = [tex]60\ \text{mph}=\dfrac{60}{3600}=\dfrac{1}{60}\ \text{miles/s}[/tex]

Time taken is given by

[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{320}{\dfrac{1}{60}}\\\Rightarrow t=19200\ \text{s}[/tex]

40 minutes break is [tex]40\times 60=2400\ \text{s}[/tex]

Total time taken is [tex]19200+2400=21600\ \text{s}=\dfrac{21600}{60\times 60}=6\ \text{hours}[/tex].

So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.

Answer:

x = √146 = 12.1 (nearest tenth)

Step-by-step explanation:

Apply pythagorean theorem, c² = a² + b², where,

c = x

a = √82 km

b = 8 km

Plug in the values

x² = (√82)² + 8²

x² = 82 + 64

x² = 146

x = √146 = 12.1 (nearest tenth)

Answer:

45 minutes

Step-by-step explanation:

so  1 hr= 60 minutes  so you do 3/4 x 60min which is  45 minutes. Feel Free to mark Brainliest and have a great day!

3/4 of an hour is equal to 45 minutes.

To find 3/4 of an hour, we need to multiply the value of one hour by 3/4.

One hour is equal to 60 minutes.

To calculate 3/4 of an hour:

= 3/4 x 60 minutes

= (3/4) x 60

= 45 minutes.

Therefore, 3/4 of an hour is equal to 45 minutes.
