Answer:
105/8 = 13 1/8 = 13.125
Step-by-step explanation:
The first step is to turn the (-5 5/8) into a mixed number. The mixed number you should be getting is - 45/8. The second step is to convert the (-2 1/3) into a mixed number as well, your second mixed number should be -7/3. Next multiply the two fractions, - 45/8 x (-7/3) = 315/24.
We can simplify 315/24 by dividing by 3, so you'll divide 315 divided by 3 and 24 divided by 3 and you should get ... 105/8. So 105/ 8 is equal to
13 1/8. If you need this fraction in decimal form it is 13.125.
Let w be the vector with initial point (2,0) and terminal point (3,2). Let v be the vector with initial point (2,2) and terminal point (0,I). Find the sum of these vectors: w+v. A. (3.5) B. (5.3 С. (-1,1 D. (LI) F. None of these
The vectors combined sum is equal to (-1, 1)
Given data;
Let 'w' be the vector with an initial point (2,0) and terminal point (3,2).
Let 'v' be the vector with the initial point (2,2) and terminal point (0,1).
To find the sum of two vectors, firstly;
For 'w';
w = (3 - 2)i + (2 - 0)j
w = i + 2j → (I)
For 'v';
v = (0 - 2)i + (1 - 2)j
v = -2i + j → (II)
Now,
From (I) & (II);
w + v = (i + 2j) + (-2i + j)
= -1, 1
Hence, the sum of the vectors w + v = (-1, 1)

2 1/4+2/5÷(−1/2)−1/4
Answer:
i believe its 1.2
Step-by-step explanation:
hopethishelpsya:)
The answer is 6/5.
When the numerator is always higher than or equal to the denominator, the fraction is said to be an improper fraction. When a fraction contains a whole number and a proper fraction is said to be a mixed fraction.
Write the given equation with mixed fraction to an improper fraction,
[tex]2\frac{1}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}=\frac{9}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}[/tex]
When we divide a fraction, we convert division into multiplication by turning the fraction upside down. Here, we convert the division sign before (-1/2) into multiplication by changing this fraction upside down as (-2/1).
Therefore,
[tex]2\frac{1}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}=\frac{9}{4}+\left(\frac{2}{5}\times\left(\frac{-2}{1}\right)\right)-\frac{1}{4}[/tex]
Now using the BODMAS rule, solve the bracket first. Followed by multiplication, addition, and subtraction.
[tex]\begin{aligned}2\frac{1}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}&=\frac{9}{4}-{\frac{4}{5}-\frac{1}{4}\\&=\frac{8}{4}-\frac{4}{5}\\&=\frac{40-16}{20}\\&=\frac{24}{20}\\&=\frac{6}{5}\end{aligned}[/tex]

What are the statistical measures in this problem?There are four statistical measures used in this problem, which are:
Median.Mode.Range.The mode is the observation that appears the most times, hence one of the remaining observations is of 80.
The median is the middle value of the data-set, which is the value of which 50% of the measures are less than and 50% of the measures are greater than.
In this problem, the data-set has an even cardinality, hence the median is the mean of the 4th and of the 5th element, hence, considering the median of 74, the missing element is given as follows:
(x + 75)/2 = 74.
x + 75 = 148
x = 73.
The range is the difference between the largest value and the smallest value in the data-set.
Considering the range of 16 and the highest value of 80, the remaining value is given as follows:

experimental probability = 0.6
What is experimental probability ?
Actual experiments and sufficient documentation of the occurrence of occurrences serve as the foundation for experimental probability, sometimes referred to as empirical probability. A number of real experiments are carried out in order to ascertain the likelihood of any event. Random experiments are studies that don't have a predetermined outcome. The results of such experiments are unpredictable. The likelihood of random experiments is calculated repeatedly. A trial is a repeating of an experiment that is performed a certain number of times. The experimental probability's mathematical formula is denoted by;
Probability of an Event P(E) = Number of Trials / Total Number of Occurrences of an Event
15 times were used in the experiment by Kendra.
According to the table, out of the 15 instances, we receive a blonde class leader 9 times.
Therefore, the experimental likelihood that the class leader for this week has blonde hair is = [tex]\frac{n(blonde)}{n(all trails)} =\frac{9}{15} =\frac{3}{5} = 0.6[/tex]
0.6 will be the experimental probability that this week's class leader will

A vehicle factory manufactures cars. The unit cost C (the cost in dollars to make each car) depends on the number of cars made. If cars are made, then the unit cost is given by the function C(x)=0.9x^2 - 414x + 59,366. What is the minimum unit cost? Do not round your answer.
The minimum unit cost of the car is $12232.1
How to determine the minimum unit cost?Given: cost function C(x)=0.9x² - 414x + 59,366
In order to find the minimum point, take the derivative of the cost function:
dC/dx = 2x - 414 (equate to zero and solve for x)
2x - 414 = 0
2x = 414
x = 414/2 = 207
Thus, the minimum point is at x =207
The minimum unit cost can be obtained by substituting x = 207 into the cost equation:
C(x) = 0.9x² - 414x + 59,366
C(207) = 0.9(207)² - 414(207) + 59,366
= 38564.1 - 85698 + 59,366
= $12232.1
