Answer:

Z = -0.675.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

What z-score value separates the lowest 25% of the scores from the rest of the distribution

This is Z which has a pvalue of 0.75, so Z = -0.675.

Find areas of square and triangle separately

ABDC= l x l

= 9 x 9

=81

AED= l x h x 1/2

= 9 x 9 x 1/2

=40.5

Area = 81+40.5

= 121.5 cm2

Explanation:

Consider the attached diagram.

Arc RB is centered at O and has a radius of 1. Angle ROD is designated angle α. It is duplicated as angle DOB, meaning that OD is the perpendicular bisector of chord RB. Triangles DFB and RGD are congruent (by HA). They are similar to triangle RDO by AA similarity.

Now, we can use the definitions of sine and cosine to find some segment lengths. Since the circle is of radius 1, the length RD is sin(α). Then, in triangle RGD, the length DG is sin(α)·cos(α). As we said, BF is congruent to DG, so the length BH is 2·sin(α)·cos(α). Again, by the definition of sine, BH = sin(2α). So, we have ...

  sin(2α) = 2·sin(α)·cos(α) . . . . the desired relationship

Answer:

-a > -b

Step-by-step explanation:

On a number line, every number (except zero, the origin) has both a magnitude and a direction (left or right, negative or positive).

The magnitude is how far the number is from the origin. 10 is further from zero than 6 is. And -10 is alos further from zero than -6 is.

If a < b and a,b are both positive, that means a and b are both on the right-hand side of the number line, and a is closer to the origin than b. The magnitude of a is smaller than that of b.

So if we switch the sign son both a and b, they both become negative and go over to the left-hand side of the number line. But their magntidues do not change, so a is still closer to the origin than b. Since b is now a negative number, further to the left than a, it is smaller than a.

Example: let a = 3 and b =5.  

It is true that 3 < 5.

But it is NOT true that -3 < -5. It's the other way around!

-5 < -3

So, if a < b, then -a > -b.

Answer:

eggplant cost more/pound.

Step-by-step explanation:

ep= 7$/pound

br= 5.6$/pound

     That the Egg Plant costs more.

My reasoning for this is because if you do 21 divided by 3 it equals 7 which means each pound of Egg Plant is $7. But 28 divided by 5 is 5.60. Which means, Beetroot is $5.60 per pound! So, beetroot is less than the Egg Plant!

A trinomial is a polynomial with three terms.

For example, a²b - 3ab + 2b or x² - 5x + 6.

Answer:

In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.

The definition of a trinomial is a math equation that has three terms that are connected by plus or minus notations. An example of a trinomial is 6x squared + 3x + 5.

A polynomial with three terms is called a trinomial. Trinomials often (but not always!) have the form x2 + bx + c.

Answer:

a= -6

Step-by-step explanation:

Answer:

a=-6

Step-by-step explanation:

6a+7=13+7a

subtract 7 from both sides

6a=13+7a-7

subtract 7a from both sides

6a-7a=13-7

add like terms

-a=6

divide by -1

a=-6
