This question is incomplete, the complete question is;

You have two strains of mice, one is inbred and the other is genetically heterogeneous. You examine weight differences for the mice when they are raised in the same environment. If the total variance for the inbred strain is 0.5 square ounces and total variance for the heterogeneous strain is 0.7 square ounces, what is the relative amount of variance due to genetic variation ?

Multiple Choice

A. 0.2 square ounces

B. 0.5 square ounces

C. 0.7 square ounces

D. 1.2 square ounces

Answer:

Option  A) 0.2 square ounces  is the correct answer

Step-by-step explanation:

Given that;

two strains of mice where raised in the environment and while one is inbred, the other is genetically heterogeneous.

The total variance for the inbred strain =  0.5 square ounces

total variance for the heterogeneous strain = 0.7 square ounces

relative amount of variance due to genetic variation = ?

The relative amount of variance due to genetic variation can be gotten by taking the difference of the total variance of both mice

so;

relative amount of variance due to genetic variation = variance for the heterogeneous strain - total variance for the inbred strain

we substitute our values

relative amount of variance due to genetic variation = 0.7 - 0.5

relative amount of variance due to genetic variation = 0.2 square ounces.

Therefore Option  A) 0.2 square ounces  is the correct answer

The z-score for data item 56, with a mean of 60 and a standard deviation of 4, is -1.

Option B is the correct answer.

We have,

To convert a data item to a z-score, you can use the formula:

z = (x - μ) / σ

Where:

z = z-score

x = data item

μ = mean

σ = standard deviation

In this case, the data item (x) is 56, the mean (μ) is 60, and the standard deviation (σ) is 4.

Plugging these values into the formula.

z = (56 - 60) / 4

z = -4 / 4

z = -1

Therefore,

The z-score for data item 56, with a mean of 60 and a standard deviation of 4, is -1.

Answer:

C) 2x - 1

Step-by-step explanation:

12x² - 4x - 1 =  12x² - 6x + 2x - 1

                   = 6x(2x - 1) + (2x - 1)

                   = (2x - 1) (6x + 1)

Answer:

f(x) = 3x^2 - 15x + 12

Step-by-step explanation:

All of the second degree polynomials listed have a leading coefficient of 3.

Since we are asked which has roots 4 and 1, we know we need to find the polynomial where x is a negative number, then solve for x.

f(x) = 3x^2 - 15x + 12

= 3(x^2 - 5x + 4)  --- Here, I factored out the 3.

= 3((x-4)(x-1)) --- solve for the quadratic.

Therefore, solving for x, we have

x - 4 = 0    and  x - 1 = 0

x = 4                  x = 1

Thus, this polynomial has a lead coefficient of 3 and its roots are 4 and 1.

The angle according to the given data about the triangle will be equal to 7°.

An angle results from the intersection of two lines at a point. The term "angle" describes the width of the "gap" that exists between these two rays. It's represented by the symbol ∠.

Angles are most frequently measured in degrees and radians, a measurement of roundness or rotation. Angles are a part of everyday existence.

As per the given information in the question,

The length of the sides is given as:

l = 8.7 cm

m = 2.3 cm

n = 6.6 cm

Use the formula given below to find the angle,

a² = b² + c² - 2bc cos A

The formula modified to the information will be,

m² = n² + l² - 2nl cos M

2.3² = 6.6² + 8.7² - 2(6.6)(8.7)cos M

5.29 = 43.56 + 75.69 - 114.84 cos M

-119.25 + 5.29 = -114.84 cos M

cos M = 113.96/117.84

M = cos⁻¹ 0.992

M = 7.09 ≈ 7°.

Answer:

Step-by-step explanation:

If it is parallel with the line 2x-3y=9

Both of them have same slope so

2x-3y=9 turn this into slope intercept form first

-3y=9-2x

Y=9/-3 + -2x/-3

Y=2/3x - 3 the slope of this equation is ⅔

So our new equation will be

Y=⅔x +b

Since (6,7)

On the line

6=⅔(7)+b

b= 6-14/3=4/3

Y=⅔x+4/3 (slope intercept form)

3y-2x=4 ( general equation of line )

The equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19

The equation of a line in point slope form is expressed as

y-y0 = m(x-x0)

m is the slope of the line

(x0, y0) is the point on the line.

Given the equation 2x - 3y = 9

Rewrite in standard form y = mx + b

-3y = -2x + 9

y = 2/3 x - 3

Compared with the standard, the slope of the line is 2/3

Substitute the slope and the point into the point slope equation.

y - 7 = 2/3 (x - 6)

3(y-7) = 2(x-6)

3y - 21 = 2x - 2

3y - 2x = 19

Hence the equation of the line that passes through the point (6, 7) and is parallel to the line 2x - 3y = 9 is 3y -2x = 19

Answer:

X = 38° and w = 65°.

Step-by-step explanation:

Hey there!

Looking through figure, we get;

(3x + 1)° = (2x + 9)° + 30° { Exterior angle of triangle is equal to the sum of opposite adjacent interior angles}

(3x + 1)° = 2x + 9° +30°

or, 3x - 2x = 39° - 1°

x = 38°

X = 38°

Therefore, x = 38°

For w:

(3x + 1)° + w = 180° (being linear pair)

(3*38+1 )°+ w = 180°

115°+ w = 180°

w = 180° -115°

Therefore, w = 65°

Answer:

-840

Step-by-step explanation:

"Product" means to multiply, so you multiply -24 by 35. Since -24 has a negative, negative times a positive will equal a negative number.

(Negative times negative is positive.)

(Negative times positive is negative.)

(Positive times positive is obviously positive.)

Using these simple rules, we can do this:

Simply multiply -24 by 35, or you can multiply 24 by 35 which is 840, but DON'T forget to put a negative symbol!
