Answer:
It took 6 days for Victor to read a full book.
Step-by-step explanation:
Given that Victor read 2 1/3 books in 14 days, and that it took him the same time to read each book completely, to determine the number of days it took him to read a complete book it is necessary to perform the following calculation:
1/3 = 0.333
14 / (2 + 1/3) = X
14 / 2.333 = X
6 = X
So, it took Victor 6 days to read a full book.
estimate the answer 102.3 × 4.7
Answer:
500
Step-by-step explanation:
First of, multiply all of the number by 10 to remove the decimal place ( this will make it less confusing)
So 102.3 x 10= 1023
4.7 x 10 = 47
You will have to round each of the numbers to 1 significant figure (sf) :
1023 round to 1 sf will be 1000
47 rounded to 1 sf will be 50
Then multiply these numbers:
1000 x 50 = 50000
Finally divide by 100 to get back the decimal places
(You divide by 100 because you multiplied by 10 twice, 10 x 10= 100)
You get 500
Given segment AB with points (-4, 8) and (6,3) respectively. Find the
coordinates of point P that partitions Segment AB in the ratio 3:2. The answer should be entered in the form (x,y) with out any spaces between characters.
Answer:
The answer is "Coordinates of point P= (2,5)"
Step-by-step explanation:
We are familiar with the internal division of AB by point P, i.e. 3:2, [tex]\frac{AP}{PB}= \frac{3}{2}[/tex]
Therefore, we use the internal division formula.
Points:
[tex]\to (-4,8) \ and \ (6,3)\\\\ x_1 = -4\\y_1 = 8\\x_2= 6\\y_2 =3 \\[/tex]
Formula:
[tex]\to x = \frac{(mx_2 + nx_1)}{(m + n)}\\\to y = \frac{(my_2 + ny_1)}{(m + n)}\\\\where,\\\\\to m = 3 \\ \to n = 2[/tex]
Replacing the x coordinate representations of A and B with x, we have
[tex]x = \frac{(3 \times 6 + 2 \times (-4))}{(3 + 2)}\\\\[/tex]
[tex]= \frac{(18 - 8)}{5}\\\\ = \frac{10}{5}\\\\ = 2[/tex]
Replacing the, y coordinate representations of A and B with y, we have
[tex]y = \frac{(3 \times 3 + 2 \times 8)}{(3 + 2)}\\\\[/tex]
[tex]= \frac{( 9 +16)}{(5)}\\\\= \frac{25}{5}\\\\=5[/tex]
The coordinates of point P= (2,5).

Get ready for takeoff. Change one number in the equation below to safely land the plane. 01 Press "Submit" to see if the plane lands safely. y = 2x - 7 Submit 0 5 10 -5 (8.891, -3.578) --10
Answer:
Step-by-step explanation:
Since we don't know x, let's come up with our own.
Lets chose 6 for x.
Now, let's plug in 6: y = 2 * 6 - 7
Multiply: y = 12 - 7
Subtract: y = 5
So our first point is (6, 5)
Now lets choose a second x: 5
Plug it in: y = 2 * 5 - 7
Multiply: y = 10 - 7
Subtract: y = 3
So our second point is (5, 3)
Find both of these points and your answer should look like the attached image.

Answer:
x = 9
Step-by-step explanation:
84 + (7x + 5) + (180 - (17x-1)) = 180
84 + 7x + 5 + (181 - 17x) = 180
270 + (-10x) = 180
90 = 10x
x = 9

Slope is 2, and (5, 3) is on the line.
Answer:
3 = 2(5) + b
Step-by-step explanation:
Equation for a slope is y=mx+b.
Y = Y-value on the graph
M = The slope
X = X-value on the graph
B = Y-intercept
If the coordinates are ( x, y )
Then that must mean that x = 5 and y = 3 because the numbers would replace the variables in the same order
The B-value is unknown for now but you are able to find it by solving this algebraically.
3=2(5) + b
3 = 10 + b
-10 = -10 + b
-7 = b
Because the 10 and the -10 would cancel each other. Leaving you with only -10 on the other side.

. Let X denote the wing length in millimeters of a male gallinule and Y the wing length in millimeters of a female gallinule. Assume that X is N(184.09, 39.37) and Y is N(171.93, 50.88) and that X and Y are independent. If a male and a female gallinule are captured, what is the probability that X is greater than Y
Answer:
The probability that X is greater than Y is 0.5754.
Step-by-step explanation:
It is provided that,
[tex]X\sim N(184.09, 39.37)\\\\Y\sim N(171.93, 50.88)[/tex]
It is also provided that X and Y are independent.
We need to compute the value of:
P (X > Y) = P (X - Y > 0)
Compute the mean and standard deviation of (X - Y) as follows:
[tex]E(X-Y)=E(X)-E(Y)=184.09-171.93=12.16\\\\SD(X-Y)=\sqrt{V(X-Y)}=\sqrt{V(X)+V(Y)}=\sqrt{39.37^{2}+50.88^{2}}=64.33[/tex]
Compute the the value of P (X > Y) as follows:
[tex]P(X>Y)=P(X-Y>0)\\\\=P(\frac{(X-Y)-E(X-Y)}{SD(X-Y)}>\frac{0-12.16}{64.33})\\\\=P(Z>-0.19)\\\\=P(Z<0.19)\\\\=0.57535\\\\\approx 0.5754[/tex]
Thus, the probability that X is greater than Y is 0.5754.

Answer:
Equation: x + 2 = 7/8x - 15
Solution: x = -136
Explanation:
x + 2 = 7/8x - 15
2 + 15 = 7/8x - x
17 = 7/8x - 8/8x
17 = -1/8x
17 × -8 = x
-136 = x

1. ........................
a*(1 + 0.03) = 1.03a2. ........................
a + 0.03a =1.03aWhich of the following statements best describes the value of the expression 7x + 6 when x = 5? A. The result is a fraction. B. The result is a prime number. C. The result is a composite number. D. The result is a whole number that is neither prime nor composite.
Answer: B) The result is a prime number
==================================================
Explanation:
Replace x with 5. Then use PEMDAS to simplify.
7x+6
7*5+6
35+6
41
The expression 7x+6 is equal to 41 when x = 5.
The value 41 is prime because its factors are only 1 and 41.

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.
Answer:
First, these angles are alternate interior angles.
[tex] 10x - 5 = 9x + 1 [/tex]
[tex] x = 6 [/tex]
Step-by-step explanation:
(10x - 5)° and (9x + 1)° are alternate interior angles. Thus, they are congruent to each other.
Thus, to find x, we will set each angle equal to the other.
[tex] 10x - 5 = 9x + 1 [/tex]
Solve for x. Collect like terms
[tex] 10x - 9x = 5 + 1 [/tex]
[tex] x = 6 [/tex]
