Answer: 7 miles
Step-by-step explanation:
The points for Tom's house (4, 2) and the store (-3, 2) are on the same level; they are on the same horizontal line 2 units above the x-axis.
The distance between the points is therefor the difference between the x coordinates.
4 - (-3) = 7
You can also just count the spaces between the points!

Question:
A number cube with faces labeled from 1 to 6 will be rolled once. The number rolled will be recorded as the outcome.
Give the sample space describing all possible outcomes. Then give all of the outcomes for the event of rolling a number greater than 2.
If there is more than one element in the set, separate them with commas.
Answer:
[tex]S = \{1,2,3,4,5,6\}[/tex]
[tex]Greater2 = \{3,4,5,6\}[/tex]
Step-by-step explanation:
Given
A roll of a 6 sided number cube
Solving (a): The sample space
This implies that we list out all number on the number cube.
So:
[tex]S = \{1,2,3,4,5,6\}[/tex]
Solving (b): Outcomes greater than 2
This implies that we list out all number on the number cube greater than 2 i.e. 3 to 6.
So:
[tex]Greater2 = \{3,4,5,6\}[/tex]
Write in slope form : -5x+15y=-30
Answer:
hope this helps
Step-by-step explanation:
y=1/3x-2 is the slope form of -5x+15y=-30.
What is straight line?a line is an infinitely long object with no width, depth, or curvature.
The given equation is -5x+15y=-30
minus five x plus fifteen y equal to minus thirty.
The standard form or slope form of a line is
y=mx+c
Where m is the slope and c is y intercept.
We need to convert -5x+15y=-30 to standard form or slope intercept form of a line.
-5x+15y=-30
15y=-30+5x
15y=5x-30
Divide both sides by 15
y=5/15 x-30/15
y=1/3x-2
Hence y=1/3x-2 is the slope form of -5x+15y=-30.

use Euler's formula to find the missing number
faces: 25
verticies: 17
edges: ?
answer choice-
a. 43
b. 41
c. 39
d. 40
Answer:
d. 40
Step-by-step explanation:
The number of faces, edges and vertices is related by the following formula:
[tex]V - E + F = 2[/tex]
In which V is the number of vertices, E is the number of edges and F is the number of faces.
In this question:
[tex]F = 25, V = 17[/tex]
We want to find E. So
[tex]V - E + F = 2[/tex]
[tex]17 - E + 25 = 2[/tex]
[tex]E = 42 - 2 = 40[/tex]

If a ball is dropped on the ground from a height of h meters, then the ball reaches the ground with the velocity 4.43h m/sec.
Find the velocity with which a ball reaches the ground when it is dropped from a height of 32 m.
Answer:
v = 141.76 m/s
Step-by-step explanation:
Given that,
The ball reaches the ground with a velocity of 4.43h m/sec.
We need to find the velocity of the ball at a height of 32 m.
Since, v = 4.43h
Put h = 32 m in the above expression.
v = 4.43(32)
v = 141.76 m/s
So, the velocity of the ball is equal to 141.76 m/s.

A contractor is required by a county planning department to submit 1, 2, 3, 4, or 5 forms (depending on the nature of the project) when applying for a building permit. Let y denote the number of forms required for an application, and suppose the mass function is given by p(y) 5 cy for y 5 1, 2, 3, 4, or 5. Determine the value of c, as well as the long-run proportion of applications that require at most three forms and the long-run proportion that require between two and four forms, inclusive.
Answer:
[tex](a)\ c = \frac{1}{15}[/tex]
[tex](b)\ 40\%[/tex]
[tex](c)\ 60\%[/tex]
Step-by-step explanation:
The given parameters can be represented as:
[tex]P_Y(y) \ge 0, y =1,2,3,4,5[/tex]
[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]
Solving (a): The value of c
To do this, we make use of the following rule;
[tex]\sum\limit^5_{y=1}P_Y(y_i) = 1[/tex]
Given that:
[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]
This is translated to:
[tex]c*1 + c * 2 + c * 3 + c * 4 + c * 5 = 1[/tex]
[tex]c + 2c + 3c + 4c + 5c = 1[/tex]
[tex]15c = 1[/tex]
Solve for c
[tex]c = \frac{1}{15}[/tex]
(b) The proportions of applications that requires at most 3 forms
This implies that: y = 1,2,3
So, we make use of:
[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]
Recall that:
[tex]P_y(y) = cy, y=1,2,3,4,5[/tex]
Substitute [tex]c = \frac{1}{15}[/tex]
[tex]P_y(y) =\frac{1}{15}y[/tex]
So:
[tex]P(Y \le 3) = P(Y=1) + P(y=2) + P(Y=3)[/tex]
[tex]P(Y\le 3) = \frac{1}{15} * 1 +\frac{1}{15} * 2 +\frac{1}{15} * 3[/tex]
[tex]P(Y\le 3) = \frac{1}{15} +\frac{2}{15} +\frac{3}{15}[/tex]
Take LCM
[tex]P(Y\le 3) = \frac{1+2+3}{15}[/tex]
[tex]P(Y\le 3) = \frac{6}{15}[/tex]
[tex]P(Y\le 3) = 0.4[/tex]
Express as percentage
[tex]P(Y\le 3) = 0.4*100\%[/tex]
[tex]P(Y\le 3) = 40\%[/tex]
(c) The proportions of applications that requires between 2 and 4 forms (inclusive)
This implies that: y = 2,3,4
So, we make use of:
[tex]P(2 \le Y \le 4) = P(Y=2) + P(Y=3) + P(Y=4)[/tex]
[tex]P(2 \le Y \le 4) = 2 * \frac{1}{15} + 3 * \frac{1}{15} + 4 * \frac{1}{15}[/tex]
[tex]P(2 \le Y \le 4) = \frac{2}{15} + \frac{3}{15} + \frac{4}{15}[/tex]
Take LCM
[tex]P(2 \le Y \le 4) = \frac{2+3+4}{15}[/tex]
[tex]P(2 \le Y \le 4) = \frac{9}{15}[/tex]
[tex]P(2 \le Y \le 4) = 0.6[/tex]
Express as percentage
[tex]P(2 \le Y \le 4) = 0.6 * 100\%[/tex]
[tex]P(2 \le Y \le 4) = 60\%[/tex]

[tex] ?x^{3} + {?}x^{2} + ?x + ?[/tex]
Answer:
4x^3-6x^2-6x+9
Step-by-step explanation:
I would write out the solutions as expressions and expand them:
(x-2)(x-1/2)(x-3/2)
(x^2-1/2x-2x+1)(x-3/2)
(x^2-5/2x+1)(x-3/2)
x^3-(3/2)x^2-(5/2)x+15/4+x-3/2
x^3-(3/2)x^2-(3/2)x+9/4
Next, since the leading coefficient has to be 4x^3, I could just multiply the entire expression by 4:
4x^3-(12/2)x^2-(12/2)x+36/4
4x^3-6x^2-6x+9
