Answer:
[tex]\frac{29}{8}[/tex]
Step-by-step explanation:
3[tex]\frac{3}{8}[/tex] equals to [tex]\frac{27}{8}[/tex], then we can write out the equation:
[tex]\frac{27}{8} + x = 7[/tex]
then subtract [tex]\frac{27}{8}[/tex]on both sides of the equal sign,
[tex]x = 7 - \frac{27}{8}[/tex]
and then we calculate x
[tex]x=\frac{56-27}{8}[/tex]
[tex]x=\frac{29}{8}[/tex]
Thus the answer is [tex]\frac{29}{8}[/tex]

work out (7.3 x 10^5) + (4x 10^5) in standard index form
The sum written in standard index form is 1.13*10^6
How to add numbers in scientific notation?
So here we want to add two numbers that are written in scientific notation, these are:
(7.3*10^5) + (4*10^5)
Now we can take the factor "10^5" as a common factor, so we can write:
(7.3*10^5) + (4*10^5) = (7.3 + 4)*10^5 = 11.3*10^5
Now we want to write this in standard index form (this is scientific notation), so we can have only one decimal on the left side of the decimal point, then we can write this as:
11.3*10^5 = 1.13*10^6

Answer:
x = 30, and the measure of NMO is 64°
Step-by-step explanation:
Since MO bisects LMN, it follows that LMO is congruent to NMO, and the measure of LMN is twice the measure of LMO and of NMO. So we have:
[tex]5x - 22 = 2(x + 34)[/tex]
[tex]5x - 22 = 2x + 68[/tex]
[tex]3x = 90[/tex]
[tex]x = 30[/tex]
So the measure of NMO is equal to the measure of LMO:
[tex]30 + 34 = 64[/tex]
LMO and NMO are 64°.
Answer:
x=30
MO bisects LMN
so LMO = NMO
then LMO+NMO=LMN

The correct option is (D) △ABC and △FED are not similar because the corresponding sides of the triangles are not in proportion.
What is the congruency of triangles?Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, rotate, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved.So, the two given triangles are:
△ABC and △DEF with no sides identical to the other.
Then, we can conclude that no congruency condition with a side statement is true.So, options (A) is (C) are incorrect.
∠B and ∠E do not seem to be identical.So, option (B) is also incorrect.
Since no sides are identical to each other then we can say that the given two triangles are not congruent when concluding that the answer to this problem is an option (D).
Therefore, the correct option is (D) △ABC and △FED are not similar because the corresponding sides of the triangles are not in proportion.

The probabilities of randomly picking a green counter from three different bags are given below.
Order these bags from the lowest probability to the highest probability.
Answer:
Lowest to highest
7/10 , 11/15, 4/5
Step-by-step explanation:
Probably the easiest way to do this is to convert each of the fractions to decimals which will clearly indicate which is the highest and which the lowest etc.
4/5 = 0.80
11/15 = 0.73
7/10 = 0.7
0.7 is less than 0.73 is less than 0.80
So 7/10, 11/15, 4/5
However, I am assuming they want you to work with fractions
To compare fractions you have to get all the denominators equal and then compare the numerator
To get a common denominator find the Least Common Multiple of the denominators. This is the lowest number that can be divided by all three denominators
Looking at 5, 15 and 10 we can see that 30 is divisible by each denominator. So that becomes our common denominator
Now multiply each fraction denominator by a factor to make the denominator equal to the common denominator. At the same time multiply the numerator by the same factor
4/5 = (4 x 6) / (5 x 6) = 24/30 Highest
11/15 = (11 x 2) / (15 x 2) = 22/30
7/10 = (7 x 3) / (10 x 3) = 21/30 Lowest
Looking at the numerator alone we can see that 7/10 is the lowest, 11/15 is next lowest and 4/5 the highest

two cards are selected without replacement from a standard deck of 52 cards. what is the probability that both cards are the same color (either both black or both red)? round to three decimal places.
The probability of getting both the card with same color is 0.245
Total No. of cards in a deck = 52
The cards having the same color (either black or red ) = 26 out of 52
which is 26/52
The probability of finding a card having the same color without a replacement
P = 26/52 x 25/51
[∵ After taking one card, the total no . of cards will be 51 and the card having the same color is 25]
= 1/2 x 25/51
= 0.5 x 0.49
P = 0.245098
Therefore, the probability that both cards are the same color is 0.245098
We need to round off it to three decimals, Thus
The probability that both cards are the same color is 0.245

How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value. This also works for multi-variable functions or expressions, as each instance of each variable will be replaced by their attributed values.
For this problem, the expression is given by:
16 + 4(3q + p)
The attributed values are given by:
q = 6, p = 2.
Hence the numeric value of the expression is found as follows:
16 + 4(3 x 6 + 2) = 16 + 4(18 + 2) = 16 + 4 x 20 = 16 + 80 = 96.

what is the best way to describe the term monomials
According to the definition of proportion, two ratios are in proportion when they are equal.
A monomial is an expression consisting of a single term.
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. Two ratios or fractions are equal when an equation or a declaration to that effect is utilized.
A polynomial with only one term is called a monomial. An algebraic expression known as a monomial typically has one term, but it can also have several variables and a higher degree. When 9 is the coefficient, x, y, and z are the variables, and 3 is the degree of the monomial, for instance, 9x³yz is a single term.

The transformations that maps polygon jklm to polygon nopq are described as follows:
C. Reflection across the y-axis, translation 2 units left and 6 units up, dilation with center (0,0) and scale factor 1/2.
What are the transformations that map jklm to nopq?The first transformation was a reflection, changing the orientation of the polygon.
Due to the orientation assumed with the equivalent vertices, NL, KO, PJ and MQ, the reflection was over the y-axis, with vertex O assuming coordinates (2,-2).
Since vertex O is at the y-axis, the polygon was translated 2 units left and 6 units up, with O assuming coordinates (0, 4).
The final coordinates of O are (0,2), hence the polygon was dilated with a scale factor of 1/2, as 4 x 1/2 = 2, which is the final y-coordinate of O.

4.66 let x represent the number that occurs when a green die is tossed and y the number that occurs when a red die is tossed. find the variance of the random variable (a) 2x − y ; (b) x 3y − 5.
The variance of each random variable is given as follows:
a) Var(2x - y) = 10.4165.
b) Var(x + 3y - 5) = 20.833.
What is the variance of random variable?The number that occurs when each dice is thrown is represented by an uniform variable, with bounds a = 1 and b = 6, hence the variance of each variable is calculated as follows:
Var(x) = Var(y) = (6 - 1)²/12 = 2.0833.
When two variables are added, the variance is calculated as follows:
Var(aX + bY) = a²Var(X) + b²Var(Y)
Hence, for item a, the variance is calculated as follows:
Var(2x - y) = 2²Var(x) + (-1)²Var(y) = 4Var(x) + Var(y)
The variances were calculated before, which are both of 2.0833, hence:
4Var(x) + Var(y) = 4 x 2.0833 + 2.0833 = 10.4165.
For item b, the variance is calculated as follows:
Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5).
The variance of a constant is of zero, hence Var(-5) = 0, and then:
Var(x + 3y - 5) = Var(x) + 3²Var(y) + (-1)²Var(-5) = 2.0833 + 9(2.0833) = 20.833.
