Answer:

230

Step-by-step explanation:

This year: 319 total; 33 unpopular

Last year: 394 total; 197 unpopular

Total songs over both years 319 + 394 = 713

Total unpopular over both years 713 - 483 = 230

(a) The 2nd letter to be a vowel (a, e, i, o, u) = 69000

(b) Exactly one vowel = 159600

An open sound is represented by a vowel, which is a letter. The English language has six vowels: a, e, I o, u, and occasionally y. Y can function as a consonant or a vowel depending on the context, as in the word story or yes. Vowels are a representation of open, frictionless vocal sounds.

4 letter word to be formed

Total Alphabets = 26

Repeated letters are not allowed

(a) 4 letter word, Consonant - C, vowel - V

Second letter to be a vowel

C or V = 25, V = 5, C or V = 24, C or V = 23

Number of word can form = 25 × 5 × 24 × 23 = 69000

(b) 4 letter word, in this exactly one vowel.

Number of words

V(5) × C(21) × C(20) × C(19)

C(21) × V(5) × C(20) × C(19)

C(21) × C(20) × V(5) × C(19)

C(21) × C(20) × C(19) × V(5)

Total number of words formed = 4 [5×21×20×19] = 159600

The answer to this question is:

Ratio 344:109 represents the ratio of the total votes to Jocelyn's votes.

A ratio in mathematics shows how frequently one number is contained in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of orange to lemon is eight to six (that is, 8:6, which is equal to the ratio of 4:3).

According to the question,

No. of votes Rosalia got = 124

No. of votes Jocelyn got = 109

No. of votes Danny got = 111

No. of votes received by all candidates =

= 124 + 109 + 111

= 344

So, the ratio 344:109 is the ratio of the total votes to Jocelyn's votes.

Therefore, Ratio 344:109 represents the ratio of the total votes to Jocelyn's votes.

The 14th term of the arithmetic sequence x-1x−1, 7x-77x−7, 13x-13, ...13x−13,... is  -79.

The nth term of a particular arithmetic sequence can be found by,  an = a + (n – 1)d. So in order to find the nth term, substitute the given values [tex]a_{1}[/tex] and d  into the formula. So to find the 14th term, substitute n = 14 into the equation which is the nth term.

Given,

 [tex]a_{1}[/tex]= x-1x-1

 [tex]a_{2}[/tex]= 7x-77x−7

 [tex]a_{3}[/tex]= 13x-13

 n=  14

We have to find the common difference d from differences in adjacent terms [tex]a_{1}[/tex],[tex]a_{2}[/tex],[tex]a_{3}[/tex] . That is,

[tex]a_{2}-a_{1} =a_{3} -a_{2}[/tex]

[tex]7x-77x-7-(x-1x-1)=13x-13-(7x-77x-7)[/tex]

[tex]7x-77x-7-x+x+1=13x-13-7x+77x+7\\-70x-8x=-6+6\\-78x=0\\ x=0[/tex]

Put x=0 in x-1x-1, 7x-77x-7, 13x-13

Therefore,

[tex]a_{1}[/tex] = -1

[tex]a_{2}[/tex] = -7

[tex]a_{3}[/tex] = -13

Then,  d will be [tex]-7-(-1)[/tex] or [tex]-13-(-7)[/tex]

So, d= -6

Put  [tex]a_{1}[/tex], d, and n in the equation [tex]a_{n} =a+(n-1)d[/tex]  to find the 14th term.

Therefore,

[tex]a_{14}=-1+(14-1)-6\\ =-1-78\\=-79[/tex]

The 14th term of the given arithmetic sequence is -79

Irrational

Step-by-step explanation:

It can not be square rooted, the closest squared number to 35 is 36. The square root of 36 is 6 as 6x6= 3.

Therefore it is irrational.

Answer:

see below

Step-by-step explanation:

sqrt35 is irrational since by the definition of rational: able to be expressed as a whole number or a fraction.

sqrt35 is approximatly 5.91607978. which is not able to be a whole number or a fraction

thus sqrt35 is irrational

Answer:

x is equal to 15.

Step-by-step explanation:

In this problem, it is said that ΔABC ~ ΔXYZ. This means that the shapes are the same, however they are not the same size. Here the problem is asking for the value of x when the triangle is scaled up.

Look on the triangles for where there are values on both ABC and XYZ. Notice that the hypotenuse for both triangles have a value.

The hypotenuse of triangle XYZ is 10, while the hypotenuse of triangle ABC is 25. Dividing both of those results by 10 results in a 1:2.5 ratio, meaning that the values of triangle ABC are 2.5 times larger than the values of triangle XYZ.

Knowing this, take the value of XZ on triangle XYZ, and multiply it by 2.5 to get the value of AC on triangle ABC, or x.

6 * 2.5 = 15

The value of x is 15.

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar that means that the sides are proportional.  There are a couple of ways to find x.  One way is to find the scale factor.  We can use the two corresponding sides that we know.  25 and 10 are corresponding sides.  They are both the hypotenuse of their triangles or you can say that they are both the side across from the 90 degree angle.

There is some number that I can multiple 10 by to get 25.  This is my scale factor.  This is how I can find it.

Let s = the scale factor.

10s = 25  Divide both sides of the equation by 10

s = 2.5  This means that each side of the larger triangle is 2.5 times longer than each side of the original triangle.  

To find x.  Find is corresponding side on the right and take that length and multiple it by 2.5

6 x 2.5 = 15

Another way is to set up a proportion.

[tex]\frac{10}{6}[/tex] = [tex]\frac{25}{x}[/tex]    I could cross multiply and solve for x

10x = (6)(25)

10x = 150  Divide both sides by 10

x = 15

Average:

The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set

Given :

the number of hours worked per week for five of her employees is

30, 30, 38, 35, and 30.

the average work of 6 employees is  35 hours per week

Solution :

Let, Total work per week= S

sixth person work per week=x

Total work per week= Number of people x average working hour

S= 35(6) = 210..(1)

S = 30+30+38+35+30+x

S= 163+x..(2)

By equation 1 and equation 2

210= 163+x

210-163=x

An infant may have had birthing complications that reduced the amount of oxygen in her blood if her Apgar score ranges from 7 at 1 minute to 9 at 5 minutes. In this situation, the hospital nurses will most likely vigorously dry her with a towel while holding oxygen under her nose.

The Apgar score is a recognized and practical way to report on the newborn baby's condition right after birth and their reaction to resuscitation, if necessary. One's particular neonatal mortality or neurologic prognosis cannot be predicted by the Apgar score alone, nor can it be regarded as a result of suffocation. It should also not be utilized to do so. An infant's spontaneous breathing score and the Apgar score given after resuscitation are not the same thing. An enhanced Apgar score reporting form that takes into account concurrent resuscitative treatments is encouraged by both the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists.

A hypothesis is an explanation provided for a phenomena. The correct option is B.

A hypothesis is an explanation provided for a phenomena. The scientific method demands that a hypothesis be testable in order for it to be considered a scientific hypothesis. Scientists often establish scientific hypotheses on past data that cannot be adequately explained by existing scientific ideas.

The one that cannot be used to explain why a hypothesis is true is a postulate. This is because a postulate is a statement that is considered to be true but has no supporting evidence.
