3.2x-1.7x+5.5=10
How dI yoI solve this
The value of x is 0.918 for the equation 3.2x - 1.7x + 5.5 = 10.
To determine this equation 3.2x - 1.7x + 5.5 = 10,
3.2x - 1.7x + 5.5 = 10
Subtract 10 on both side,
3.2x - 1.7x + 5.5 - 10 = 10 - 10
3.2x - 1.7x + 4.5 = 0
Subtract 4.5 on both side,
3.2x - 1.7x = -4.5.
4.9x = -4.5
x = 0.918.
Therefore, the value of x is 0.918.

find the standard deviation
Answer:
d. 7.3
Step-by-step explanation:
To get the standard deviation of a population of data, first take the sum of all the values, and divide it by the count to get the mean (average).
75 [1] + 90 [2] + 75 [3] + 80 [4] + 90 [5] + 80 [6] + 100 [7] + 85 [8] + 80 [9] + 85 [10] = 840.
Then divide by the count which is 10.
840/10 = 84 [This is the mean of the data.]
Then subtract every point of data from the mean and square it:
(75-84)^2 + (90-84)^2 + (75-84)^2 + (80-84)^2 + (90-84)^2 + (80-84)^2 + (100-84)^2 + (85-84)^2 + (80-84)^2 + (85-84)^2 = 81 + 36 + 81 + 16 + 36 + 16 + 256 + 1 + 16 + 1 = 540.
Then to get the variance, divide this all by the count.
540/10 = 54 [This is the variance of the data.]
Then all you have to do to get the standard deviation is take the square root of the variance.
√54 = 3√6 ≈ 7.3 [This is the standard deviation of the data.]

Answer:
[tex]\displaystyle \frac{199}{18}[/tex]
Step-by-step explanation:
Fraction Operations
Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.
[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]
[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]
Now for the sum of the last two fractions:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]
Make both denominators equal by multiplying by 2 both parts of the first fraction:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]
[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]
Now multiply by 7/9:
[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]
Convert 9 3/4 to an improper fraction.
Answer:
39/4
Step-by-step explanation:
Because I multiplied 4 x 9 + 3
9 3/4 may be expressed as an improper fraction as 39/4 or 9.75.
What is Fraction?
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.
9¾ is a mixed fraction. 9 is the whole number whereas ¾ is the fractional part. 9¾ is also 9+¾.
Fractions that have a numerator greater than a denominator, such as 8/7 or 123/112, are considered improper fractions.
Thus, to convert 9 3/4 into an improper fraction, multiply the whole number component—in this case, 9, by the denominator (4 in this case). The multiple of 9 and 4 you just discovered is added to the numerator (3), which is then used as the numerator. The numerator (four) stays the same.
Therefore, 9 3/4 can be written as 39/4 or 9.75 in the terms of the improper fraction.

What is rounding up numbers?
There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Given data ,
Let the number be = A
Let the rounded number be = B
The value of A is given by
A = 531.775197122
Now , the number A can be rounded of to the nearest ten thousandth place by rounding to the nearest 0.0001 or the Ten Thousandths Place
So , the number will be
The 1 in the ten thousandths place rounds up to 2 because the digit to the right in the hundred thousandths place is 9
When the digit to the right is 5 or greater we round away from 0
Therefore , the number 531.775197122 is rounded to 531.7752
Therefore , the value of B is 531.7752 after rounding up
Hence , The number 531.775197122 is rounded to the nearest ten thousandth place by 531.7752
