is 20 9/10 equal to 18

Answer:

The size of the sample is 840.

The probability that the first three letters of the four-letter code are vowels is=\frac{1}{35}=

35

1

Step-by-step explanation:

Th total number of letters given to form code of 4 letters = 7

Since, the order of the letters in the code matters, which means there is no repetition.

The total number of ways to form the code size =7*6*5*4=8407∗6∗5∗4=840

Therefore, The size of the sample is 840.

Since, there are 3 vowels and rest of 4 letters are consonant.

The number of ways to form code such that the first three letters of the four-letter code are vowels =3\times2\times1\times4=243×2×1×4=24

The probability that the first three letters of the four-letter code are vowels is

=\frac{24}{840}=\frac{1}{35}

840

Answer:

m<R = 22.62°

Step-by-step explanation:

Reference angle = R

Opposite = 5 cm

Hypotenuse = 13 cm

Apply the trigonometric function SOH:

Sin R = Opp/Hyp

[tex] Sin (R) = \frac{5}{13} [/tex]

[tex] R = sin^{-1}(\frac{5}{13}) [/tex]

R = 22.6198649°

m<R = 22.62° (nearest hundredth)

For an isosceles triangle, the area can be easily calculated if the height (i.e. the altitude) and the base are known. Multiplying the height with the base and dividing it by 2, results in the area of the isosceles triangle.

====================================================

Explanation:

The equation is in the form y = a*(b)^x

The 'a' is the initial or starting value. In this case, a = 15.

The b is the base of the exponent which is tied to growth or decay. If 0 < b < 1, then we have decay. If b > 1, then we have growth.

Since b = 1.35, and 1.35 > 1, this means b > 1 and the given equation represents exponential growth.

Solving 1+r = 1.35 leads to r = 0.35. This means the growth rate is 35%

Answer:

K = - 6

Step-by-step explanation:

Let's solve your equation step-by-step.

2(4k+5)+3(3−3k)=25

Step 1: Simplify both sides of the equation.

2(4k+5)+3(3−3k)=25

(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)

8k+10+9+−9k=25

(8k+−9k)+(10+9)=25(Combine Like Terms)

−k+19=25

−k+19=25

Step 2: Subtract 19 from both sides.

−k+19−19=25−19

−k=6

Step 3: Divide both sides by -1.

Answer:

32

Step-by-step explanation:

Given the algebraic expression;

[tex] 3x^{2} + 2(x + 4x) = 0 [/tex]

When x = 2

It simply means that we would substitute the value of x into the equation.

[tex] 3*2^{2} + 2(2 + 4*2) [/tex]

[tex] 3*4 + 2(2 + 8) [/tex]

[tex] 12 + 2(10) [/tex]

[tex] 12 + 20 [/tex]

[tex] 12 + 20 = 32 [/tex]

Step-by-step explanation:

< AEB + < BEC = 180° {BEING LINEAR PAIR }

26° + < BEC = 180°

< BEC = 180° - 26°

< BEC = 154°

ARC BC = < BEC ( relation between arc and central angle)

Arc BC = 154°

Answer:

25

Step-by-step explanation:

ok so you need to find out how much each game is sold for

First 37.50 divided by 3 and that will equal 12.5

second, you need to find out how much 2 games cost so you  eithermultiply

12.5 by 2 or add 12.5 two times and you will get 25

hope this helped;)

Answer:

120 ft

Step-by-step explanation:

60/360 or 1/6 of circle = 20 ft

full circle = 20 x 6 = 120 ft

diameter = 120/3.14 = 38.22 ft

radius = 38.22/2 = 19.11 ft

Answer:

Step-by-step explanation:

60° = ⅙ of 360°, so length of arc LM = ⅙ of 2πr.

20 = 2πr/6

r = 60/π ft

Answer:

3

Step-by-step explanation:

Answer:

a) clusters: none, gaps: 99, and 100, peaks: 101, outliers: none.

b) center of distribution:

median: 101, mean: 99.9090.

(a)

The outliers are the values that are far from the middle.

In this case, the outliers are 97, 98, 98, 98.

A cluster occurs when the data occurs within a small interval.

In this case, there's a cluster between 100 and 102.

According to the dot plot, there's a gap from 98 to 101.

At last, the peak is at 101, which is the value with the highest frequency.

(b)

The given data set doesn't form a normal distribution because there's no data in the middle of the data set, instead, there's a gap. Additionally, the spread or range of the data set is 5, where the majority of the data is not in the middle which mean the dispersion of the data is important.

Answer:

(3x - 5)(2x - 1)

Step-by-step explanation:

6x² - 13x + 5

6x² - (10 + 3)x + 5

6x² - 10x - 3x + 5

2x(3x - 5) - (3x - 5)

(3x - 5)(2x - 1)

Which means, 6x² - 13x + 5 is equivalent to (3x - 5)(2x - 1) or vice versa
