What percent is the shaded portion of the entire diagram? A bar diagram with 9 shaded squares and 11 unshaded squares. 9% 40% 45% 90%
Answer:45%
Step-by-step explanation: Here you have 9 shades out of 20 .and to write any number as a percent you must put the denominator as 100.. so multiply both numerator and denominator by 5 .. so it will be 45 out of 100 instead if 9 out of 20

A food-protection agency counts the number of insect heads found per 100-gram batch of wheat flour. The researchers have 500 batches, and they want to know whether the frequency of insect heads in batches follows a distribution called a Poisson distribution. To generate the expected frequencies of batches with different numbers of insect heads under a Poisson distribution, they had to estimate the mean number of insect heads per batch from the data. The 500 batches included at least 5 batches having 0, 1, 2, 3, or 4 insect heads. No batches had more than four heads. Given this information, there are_____classes (k).
Answer:
The correct answer is k = 5.
Step-by-step explanation:
The Chi-square goodness of fit test would be used to determine whether the frequency of insect heads in batches follows a distribution called a Poisson distribution.
The hypothesis for the test can be defined as follows:
H₀: The frequency of insect heads in batches does not follows a Poisson distribution.
Hₐ: The frequency of insect heads in batches follows a Poisson distribution.
Assume that the significance level of the test is, α = 0.05.
The Chi-square test statistic is given by:
[tex]\chi^{2}=\sum\limits^{k}_{i=1}\frac{(O_{i}-E_{i})^{2}}{E_{i}}[/tex]
It is provided that the 500 batches included at least 5 batches having 0, 1, 2, 3, or 4 insect heads. No batches had more than four heads.
So, the number of classes or categories are, k = 5.
Thus, the correct answer is k = 5.
Suppose A is a 5x7 matrix. How many pivot columns must A have if its columns span R^5? Why?
a. The matrix must have nothing pivot columns. If A had fewer pivot columns, then the equation A would have only the trivial solution.
b. The matrix must have nothing pivot columns. The statements "A has a pivot position in every row" and "the columns of A span " are logically equivalent.
c. The matrix must have nothing pivot columns. Otherwise, the equation A would have a free variable, in which case the columns of A would not span .
d. The columns of a 57 matrix cannot span because having more columns than rows makes the columns of the matrix dependent
Answer:
The answer is "Option B".
Step-by-step explanation:
In the given choices there is some mistake so, the correct choice can be defined in the attached file. please find it.
In the given question, If the column of [tex]5 \times 7[/tex] matrix, and the A span is equal to [tex]R^5[/tex], and then the value of A has a pivot in each row, that's why in each pivot its position in the different columns of A has the five pivot columns, that's why the choice B is correct.

l------- l l_____. l l. ____ l
l. l. l_____. l_____ l
Answer:
780
Step-by-step explanation:
17 is the divisor, while 2635 is the dividend. So that,
[tex]\frac{2635}{17}[/tex] = 155
The quotient = 155 = 1 hundreds, 5 tens and 5 units
Also,
2635 - 1700 = 935
Hence, let the unknown value be represented by x. Then;
935 - x
The answer of the subtraction should be equal to the quotient of the division.
935 - x = 155
935 - 155 = x
780 = x
Therefore the unknown value represented by a box is 780.

Find the point P that is 2/5 of the way from A to B on the directed line segment AB if A (-8, -2) and B (6, 19).
The location of the point P that is 2/5 of the way from A to B on the directed line segment AB if A(x, y) = (- 8, -2) and B(x, y) = (6, 19) is P(x, y) = (- 12/5, 32/5).
How to determine the location of a point within a line segment
By geometry we know that a line segment is generated from two distinct points set on a plane. The location of the point P within the line segment can be found by means of the following vectorial formula:
P(x, y) = A(x, y) + k · [B(x, y) - A(x, y)], 0 < k < 1 (1)
Where:
A(x, y) - Initial pointB(x, y) - Final pointk - Distance factorIf we know that A(x, y) = (- 8, - 2), B(x, y) = (6, 19) and k = 2/5, then the location of the point P is:
P(x, y) = (- 8, -2) + (2/5) · [(6, 19) - (- 8, -2)]
P(x, y) = (- 8, -2) + (2/5) · (14, 21)
P(x, y) = (- 12/5, 32/5)
The location of the point P that is 2/5 of the way from A to B on the directed line segment AB if A(x, y) = (- 8, -2) and B(x, y) = (6, 19) is P(x, y) = (- 12/5, 32/5).

Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0, 1) The equation ex = 3 − 2x is equivalent to the equation f(x) = ex − 3 + 2x = 0. f(x) is continuous on the interval [0, 1], f(0) = _____, and f(1) = _____. Since f(0) < 0 < f(1) , there is a number c in (0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation ex = 3 − 2x, in the interval (0, 1)
Answer:

According to intermediate value theorem, if a function is continuous on an interval [tex][a,b][/tex], and if [tex]k[/tex] is any number between [tex]f(a)[/tex] and [tex]f(b)[/tex], then there exists a value, [tex]x=m[/tex], where [tex]a<m<b[/tex], such that [tex]f(m)=k[/tex]

Given the probability that "she's up all night 'til the sun" OR "she's up all night for good fun" is 0.36, the probability that "she's up all night for good fun" is 0.41, and the probability that "she's up all night 'til the sun" is 0.36, what's the probability that "she's up all night 'til the sun" AND "she's up all night for good fun"?
Answer:
0.41
Step-by-step explanation:
S = "she's up all night 'til the sun"
F = "she's up all night for good fun"
P(S or F) = P(S) + P(F) − P(S and F)
0.36 = 0.36 + 0.41 − P(S and F)
P(S and F) = 0.41

m∠3 = 57. Find m∠1. (I'm just typing here to meet the 20 character min.)
Answer:
The correct answer is 57 degrees.
Step-by-step explanation:
To solve this problem, we must remember that vertical angles (angles that are across from each other) are congruent, which means that they have the same measure.
In the diagram, angle 3 and angle 1 are vertical angles, so we can conclude that they have the same measure.
Therefore, m<1 = m<3 = 57 degrees.
