A bag contains ten tiles labeled B, C, D, E, F, G, H, I, J, and K. One tile will be randomly picked.
What is the probability of picking a letter that is not a vowel?

The correlation coefficient of the health research institute data measures the relationship between the age and the years of the smokers

The correlation coefficient is 0.53

The correlation coefficient (r) is calculated as:

[tex]r = \frac{n(\sum xy) - \sum x \sum y}{\sqrt{[n \sum x^2 - (\sum x)^2][n\sum y^2 - (\sum y)^2}}[/tex]

Using the given parameters, we have:

[tex]r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1257^2][20 * 836 - 116^2}}[/tex]

Evaluate the exponents

[tex]r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1580049][20 * 836 - 13456}}[/tex]

Evaluate the products

[tex]r = \frac{164980 - 145812}{\sqrt{[1976460 - 1580049][16720 - 13456}}[/tex]

Evaluate the differences

[tex]r = \frac{19168}{\sqrt{[396411*3264}}[/tex]

Evaluate the product

[tex]r = \frac{19168}{\sqrt{1293885504}}[/tex]

Evaluate the root

[tex]r = \frac{19168}{35970.6}[/tex]

Evaluate the quotient

[tex]r = 0.53[/tex]

Hence, the correlation coefficient is 0.53

answer will be 3x+4 = 3x+4 i.e, 0=0 ,so

but if 3x+4 = 0 , x= -4/3 . Its a linear equation and has only one solution

Answer:

Infinitely many solutions.

Step-by-step explanation:

3x + 4 = 3x + 4

3x = 3x

Divide 3 from both sides.

x = x

Therefore, this equation has infinitely many solutions.

Answer:

6.25 & 8.25

Step-by-step explanation:

im probably wrong lol-

29/2 = x+x+2

14.5=2x+2

12.5=2x

therefore x = 6.25 but to fin the other x add 2

so then the longer piece would be 8.25

[tex]\red\leadsto[/tex]Let one piece of glass tubing be of length x in ,

[tex]\green\leadsto[/tex]then other piece will be of length(x+2) in since it is 2 in longer than other piece

[tex]\\[/tex]

>>>Total length of both the piece

= 29 in _ _ _ (1)

>>>Total length of both pieces = length of shorter piece + length of longer piece

[tex]\:\implies[/tex] Total length of both pieces = x+(x+2) _ _ _(2)

[tex]\\[/tex]

Equating (1) and (2)

[tex]\:\implies[/tex]x+(x+2) = 29

[tex]\:\implies[/tex]x+x+2= 29

[tex]\:\implies[/tex]2x+2 = 29

[tex]\:\implies[/tex]2x= 29-2

[tex]\:\implies[/tex]x= 27/2

[tex]\\[/tex]

>>Length of smaller piece =

[tex]\:\implies[/tex]x = 27/2 in

>>> Length of larger piece =

[tex]\:\implies[/tex](x+2) = 27/2 + 2 = 31/2 in

[tex]\\[/tex]

[tex]\longrightarrow[/tex]Thus, The pieces are 27/2 in and 31/2 in long

Answer:

A, C, E

Step-by-step explanation:

under the same denominator r(r-4)

[6(r-4)] / (r(r-4)) + (4r) / (r(r-4)) = 1

(6r - 24 + 4r) / (r(r-4)) = 1

10r - 24 = r (r-4)

10r - 24 = r² - 4r

r² - 14r + 24 = 0

Δ = (-14)² - 4*1*24 = 100 = 10²

x' = (14 + 10) / 2 = 12

x" = (14 - 10) / 2 = 2

Answer:

In order from left to right: [tex]-\frac{4}{3}, -\frac{4}{5}, -\frac{2}{3}, \frac{7}{10}, \frac{7}{8}[/tex]

Step-by-step explanation:

[tex]-\frac{4}{3}[/tex] is the only improper fraction because the numerator is greater than the denominator and since it is negative, that means that it is the least.

[tex]-\frac{4}{5}[/tex] as the decimal -0.8 is closer to -1 than [tex]-\frac{2}{3}[/tex] as the decimal -0.666...

[tex]\frac{7}{8}[/tex] as the decimal 0.875 is closer to one than [tex]\frac{7}{10}[/tex] as the decimal 0.7...

Vectors are elements of the vector space, and they can be illustrated by diagrams.

The vector expression is given as:

2u - 1/3 v

Split the vector expressions, as follows:

[tex]y_1 = 2u[/tex]

[tex]y_2 = -\frac13v[/tex]

See attachment for the graphs of y1 and y2.

Next, we have:

[tex]y = 2u - \frac13v[/tex]

So, we have:

[tex]y = y_1 + y_2[/tex]

The above expression means that, we add the vectors y1 and y2 to get vector y

See attachment for the graph of 2u - 1/3 v

Answer:

2B / (mx) = y

Step-by-step explanation:

B = 1/2 mxy

Multiply each side by 2

2B = 2* 1/2 mxy

2B = mxy

Divide each side by mx

2B / (mx) = mxy / (mx)

2B / (mx) = y

Answer:

[tex] \huge y = \frac{2B}{mx} \\ [/tex]

Step-by-step explanation:

[tex]B = \frac{1}{2} mxy \\ [/tex]

Multiply through by 2 to eliminate the fraction

That's

[tex]mxy = 2B[/tex]

Divide both sides by mx to make y stand alone

We have

[tex] \frac{mxy}{mx} = \frac{2B}{mx} \\ [/tex]

We have the final answer as

[tex]y = \frac{2B}{mx} \\ [/tex]
