Step-by-step explanation:
when it is divided by 5 we easily know the last digit is 0 or 5
it os odd it can't divided to 2
the some of each digit is 17
so the answer will be 170
170÷5=34
170<400
1+7+0=17 true
485÷5=97
4+8+5=17
but 485>17 false

The following are the Pulse Rates of the 12 students in a Math Class
76 60 59 60
81 72 91 80
80 68 73 77
If we create Classes for a relative frequency distribution.
For the Class 50-59 , find the frequency
Answer:
1
Step-by-step explanation:
Given the pulse rate for 12 students :
76 60 59 60 81 72 91 80 80 68 73 77
Creating class intervals ::
Width = 10
59, 60, 60, 68, 72, 73, 76, 77, 80, 80, 81, 91
Interval ____ Frequency
50 - 59 ______ 1
60 - 69 ______ 3
70 - 79 ______ 4
80 - 89 ______ 3
90 - 99 ______ 1
Frequebcy if the 50 - 59 class interval is 1
3.(8 points)Consider the following experiment:Experiment: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3yellow balls. Two balls are drawn from the bag without replacing the ballafter the first draw.(a)(2 points)Specify the sample space (set of outcomes) and probability distributionof the outcomes.(b)(3 points)If you draw two balls from the bag without replacing them, what isthe probability of drawing two red balls
Answer:
3 / 91
Step-by-step explanation:
Given :
Red balls = 3
Blue balls = 4
Green balls = 4
Yellow balls = 3
Total number of balls = (3+4+4+3) = 14
Sample space :
RR, BB, GG, YY, RB, BR, BG, GB, YG, GY, YR, RY, BY, YB, GR, RG
Probability of drawing two red balls without replacement :
1st draw :
P(red) = number of red balls / total number of balls
P(red) = 3/14
2nd draw :
P(red) = 2 / 13
Hence,
P(RR) = 3/14 * 2/13 = 6 / 182 = 3 / 91
Which statements are correct? Check all that apply.

About 5% of the population has a particular genetic mutation. 200 people are randomly selected.
Find the mean for the number of people with the genetic mutation in such groups of 200.
Answer:
ok 200 we have to find 5% of 200 so since 200 is doable 100 we just multiply 5 by 2 to get 10
so out of the 200 people 10 of them have the mutation

Joseph has 22 gallons of fertilizer. He uses 7 quarts to fertilize his plants.
How many quarts of fertilizer are left?
Answer:
81
Step-by-step explanation:
4 quarts = 1 gallon
there are 22 gallons so multiply 4 by 22
that equals 88 quarts then subtract 7
leaving you with 81 quarts

Rectangle ABCD is transformed to A’B’C’D’ by a dilation. What is the scale factor used for the dilation?
Answer:
Scale factor = 3
Step-by-step explanation:
Scale factor used for the dilation = the ratio of the corresponding side length of the new figure to the side length of the original figure
Scale factor = B'C'/BC
B'C' = 9 units
BC = 3 units
Scale factor = 9/3 = 3
what are the principle and symmetric solutions to the equation 2cos(x)=-1
Answer:
Assuming that x is in degrees (you could generalize this to any unit)
For an equation like:
sin(a*x) = K
The principle solutions are the values of x in the range:
0° ≤ x < 360°
And the symmetric ones are the solutions:
xₙ = x + n*360°
where n is an integer.
Ok, first let's solve:
2*cos(x) = -1
isolating the cosine part, we get:
cos(x) = -1/2
Now we can use the inverse cosine function, Acos(x)
If we apply this function to both sides, we get:
Acos (cos(x)) = Acos(-1/2)
x = Acos(-1/2) = 120°
x = 120° is the princpiple solution.
And the symmetric solutions are:
xₙ = 120° + n*360°
So for example:
x₁ = 120° + 1*360° = 480°
x₃ = 120° + 3*360° = 1200°
etc...

Find the measurement of the numbered angles
Answer:
m<1 = 60
m<2 = 30
m<3 = 80
Step-by-step explanation:
1. Solve for angle (1)
The sum of angles in any triangle is (180) degrees. As one can see, there is a (30) degree angle in this triangle, and a (90) degree angle. Bear in mind that the box around an angle indicates that it is a (90) degree angle. One can form an equation and solve for the unknown angle using this given information;
(30) + (m<1) + (90) = 180
Simplify,
120 + m<1 = 180
Inverse operations,
m<1 = 60
2. Solve for angle (2)
The vertical angles theorem states that when two lines intersect, the angles opposite each other are congruent. One can apply this theorem here by stating the following,
m<2 = 30
Thus one gets their answer, the measure of angle (2) must be (30) degrees by the vertical angles theorem.
3. Solve for angle (3)
As states above, the sum of angles in a triangle is (180) degrees. Since one has found the measure of angle (2), one can form an equation and solve for the measure of angle (3) using the given information, combined with the information found.
(m<2) + (70) + (m<3) = 180
Susbtitute,
30 + 70 + (m<3) = 180
Simplify,
100 + m<3 = 180
Invers eoperations,
m<3 = 80

C. 2+2 > z>b-a
D. z> a +b-2>Z
E. 2+b>z< 2-a
F. None of the above
Answer:
[tex]2 + b >z > 2 -a[/tex]
Step-by-step explanation:
Given
[tex]z - b < 2 < a + z[/tex]

Solve for z
Split the inequality
[tex]z - b < 2[/tex] or [tex]2< a + z[/tex]
Make z the subject
[tex]z < 2 + b[/tex] or [tex]2 - a < z[/tex]
Rewrite as:

a total of 10000 was invested in two business ventures A and B .at the of the first year A and B yielded returns of 6% and 23÷4 respective on the original investment how was the original amount allocated if the total amount earned was 588.75?
Answer:
(1)
compound amount = 802.5 $
invest earned = 52.5 $
Step-by-step explanation:
total amount = 10000 $
let amount x invested in ventures A and remaining (1000-x) on ventures B
now,
6x/100 +23/400(1000-x ) = 588.75
{24x+23(1000-x)}/400 =588.75
x=235500-230000
x=5500
Amount invested on A = 5500$
Amount invested on B = 4500$
(2)
principle=750$
time= 1 year
effective invest rate = 7%
a) compound amount = p(1+(r/w)^t
=750{1+(7/100)}^1
=802.5$
b) invest earned = 802.5-700 = 52.5$
15. PLZ HELP For each part below, use the figure to fill in the blank. If necessary, you may learn what the markings on a figure indicate. (a) Find Q (b)Find m < M.
Answer:
a. m<Q = 75°
b. m<M = 60°
Step-by-step explanation:
a. The triangle has two equal sides, therefore it is an isosceles triangle. Thus, its base angles would be equal also. m<Q = m<S
Therefore:
m<Q = ½(180 - 30)
m<Q = 75°
b. All sides of the triangle are equal. Therefore, it is an equilateral triangle with equal angles measuring 60° each.
m<M = 60°

x^ 3 + 3 x ^ 2 - 9 x - 27 draw the graph of the first derivative and the second derivative on the same set
Answer:
The graph is in the second attached image.
Step-by-step explanation:
In the first attached image, you have three equation graphed, the first is in red color, it's the original equation:
x^3 + 3x^2 - 9x - 27I graphed this to obtain a clear relation between the equation and its derivatives, the second graphed equation is in blue color and it's the first derivative:
First derivative = 3x^2 + 6x - 9 (It's a parabola)And at last, we have in green color the second derivative:
Second derivative = 6x + 6 (It's a line)As you can see, you only need the first and the second derivatives in the exercise, by this reason, in the second attached image you have the graph as you need to show in this exercise.

what is equivalent to 7w +7w
Answer:
14w
Step-by-step explanation:
I don't know how to explain it any simpler than just to give you the answer which is 14w.
There is a more mathematical way of getting the 14w, but I'm guessing you won't like it. Use the distributive property. Put brackets around the given expression
7w + 7w = (7w + 7w)
On each side of the plus sign there is a common factor and that common factor is w
w(7 + 7) Now add the two 7s together.
14w
You could say to me, why didn't you take out the 7 to start with. You could
7 ( w + w) but w and w add up to 2w
7*2w
14 w
