Answer:
4/5
Step-by-step explanation:
There are 10 tiles total, and E and I are vowels. This makes 2/10 of the tiles tiles. The other 8/10 are not vowels.
8/10 can be simplified down to 4/5.
There is a 4/5 probability of picking a letter that is not a vowel.

solve the literal equation for y.
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]

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

Sarah works two jobs over the summer. She is a waitress, earning $11 per hour, and she is also a babysitter for three kids, earning $18 per hour. Sarah currently waitresses 16 hours and babysits 3 hours a week. She would like to increase her babysitting hours and decrease her waitressing hours by the same number of hours. Write an expression to represent how this change would affect her weekly income.
HELP PLZ
Answer:
Step-by-step explanation:
Before the change she made $230 a week because 11x16=176 + 18x3= 54
but after the change she would make $321 a week because 18x16= 233 + 11x3= 33

We multiply from 1.25 because to get from 3 euros. 4 pounds is 1.25
A health research institute collects information from 20 individuals on the number of years they have spent smoking cigarettes, and their age of death. The data is summarized below:
∑x=1257
∑y^2=836
∑x^2=98823
∑y=116
∑(xy)=8249
Find the correlation coefficient (r):
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
How to calculate the correlation coefficientThe 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

3x+4 = 3x+4
Answer:
it has no solution.......
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.

Use vector operations to draw the resultant vector.
b) Draw 2u – 1 /3 v.
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe 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

lab technician cuts a 29 in piece of glass tubing into two pieces. One piece is 2 in longer than the other. How long are the pieces?
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
