Answer:

[tex]Sum = 832[/tex]

Step-by-step explanation:

Given

See attachment

Required

Evaluate

The expression can be expressed as:

[tex]Sum = 2n + 5;\ n=1...26[/tex]

To do this, we  make use of sum of n terms of an AP.

When n = 1

[tex]2n + 5 = 2 * 1 + 5 = 7[/tex] --- T1

When n = 2

[tex]2n + 5 = 2 * 2 + 5 = 9[/tex] --- T2

When n - 26

[tex]2n + 5 = 2 * 26 + 5 = 57[/tex] --- T26

Next, we calculate d (common difference)

[tex]d = T_2 - T_1[/tex]

[tex]d = 9 - 7 = 2[/tex]

So, the sum is:

[tex]Sum = \frac{n}{2}(T_1 + T_n)[/tex]

Let n = 26

So, we have:

[tex]Sum = \frac{26}{2}(T_1 + T_{26})[/tex]

Substitute values for T1 and T26

[tex]Sum = \frac{26}{2}(7+57)[/tex]

[tex]Sum = \frac{26}{2}(64)[/tex]

[tex]Sum = 13*64[/tex]

[tex]Sum = 832[/tex]

What is the image of (-10,-6) after dilation by a scale factor of 1/2 ​centered at the origin?

Answers

The coordinate of resulting image after dilation is (-5, -3)

Dilation and scale factors

Given the coordinate of an image (-10,-6), dilating the coordinate by 1/2 means reducing the image by multiplying each coordinate by the factor of 1/2.

Image = (1/2(-10), 1/2(-6))

Image = (-5, -3)

From the calculation above, you can see that the coordinate of resulting image after dilation is (-5, -3)

The explicit formula for the geometric progression is f ( x ) = 3 ( 4 )ˣ⁻¹

What is Geometric Progression?

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric progression be represented as A

Now , the value of A is

f ( x + 1 ) = 4 f ( x )

where the second term is a₂ = 12

Now , the explicit formula is given by

f ( x ) = 3 ( 4 )ˣ⁻¹

when x = 2

f ( 2 ) = 3 ( 4 )²⁻¹

f ( 2 ) = 3 ( 4 )

f ( 2 ) = 12

Hence , the GP is f ( x ) = 3 ( 4 )ˣ⁻¹

Let x be the height of the tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2. Let us represent this information in an equation.

5/8*x=2 and 1/2

Let us convert our given mixed fraction into an improper fraction.

5/8*x=5/2

Let us multiply both sides of our equation by 8/5.

8/5*5/8*x=5/2*8/5

x=8/2

Which of these equations are true when the value of y is 27?
I. −9 + y = 18
II. −18 + y = −45
III. 5y = 135
IV. 2y = 29

Answers

Answer:

I. -9 + y = 18

Step-by-step explanation:

Double-check to see if I was correct

The equations I. and III. satisfies the condition when y = 27

What is an Equation?

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 ,

The value of y = 27

So , substituting the value of y in all of the given equations , we get

I.  

-9 + y = 18

when y = 27

Substituting the value of y , we get

-9 + 27 = 18

18 = 18

So , I. satisfies the condition and the equation is TRUE

II.

-18 + y = 45

when y = 27

Substituting the value of y , we get

-18 + 27 = 45

9 ≠ 45

So , II. does not satisfy the condition and the equation is FALSE

III.

5y = 135

when y = 27

Substituting the value of y , we get

5 x 27 = 135

135 = 135

So , III. satisfies the condition and the equation is TRUE

IV.

2y = 49

when y = 27

Substituting the value of y , we get

2 x 27 = 29

54 ≠ 29

So , IV. does not satisfy the condition and the equation is FALSE

Hence , the equations I. and III. are TRUE

Step 1: Find angle G

Since Sin(θ) = Opposite over Hypotenuse:

θ = 33.896°

Now repeat for just the smaller triangle:

Suppose that 11% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). Consider a random sample of 200 shafts, and let X denote the number among these that are nonconforming and can be reworked. (Round your answers to four decimal places.) (a) What is the (approximate) probability that X is at most 30

Answers

Answer:

0.9726 = 97.26% approximate probability that X is at most 30

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Normal probability distribution

Problems of normally distributed 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.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].

11% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).

This means that [tex]p = 0.11[/tex]

Random sample of 200 shafts

This means that [tex]n = 200[/tex]

Mean and Standard deviation:

[tex]\mu = E(x) = np = 200*0.11 = 22[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{200*0.11*0.89} = 4.42[/tex]

(a) What is the (approximate) probability that X is at most 30

Using continuity correction, this is [tex]P(X \leq 30 + 0.5) = P(X \leq 30.5)[/tex], which is the pvalue of Z when X = 30.5. So

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

[tex]Z = \frac{30.5 - 22}{4.42}[/tex]

[tex]Z = 1.92[/tex]

[tex]Z = 1.92[/tex] has a pvalue of 0.9726.

0.9726 = 97.26% approximate probability that X is at most 30

In 1777, Boyrereau Brinch, an enslaved African, joined the Continental Army. In 1783, he was honorably discharged and, because of his military service, freed from slavery. I also entered the banners of freedom. Alas! Poor African Slave, to liberate these freemen, my own tyrants. I went into Capt. [Samuel] Grangers company. We marched to Frog Plain, from there to Second Hill between Reading and Ridgold. General Worcester commanded the British under the command of General Howe, who attacked us. We beat them back; the fight was continued all day, and the victory was sometimes doubtful.

All of which are battles the reader can obtain a more perfect account of from history than I can give. At last we returned to West Point and were discharged, as the war was over. Thus was I, a slave for five years fighting for liberty. After we were disbanded, I returned to my old master at Woodbury [Connecticut], with whom I lived one year, my services in the American war having emancipated me from further slavery and from being bartered or sold.
