Jenny is taking a vacation from Florida. She travels 70 kilometers per hour for 2 hours, and 63 kilometers per hour for 5 hours. Over the 7 hours time period what was Jenny's average speed?
Answer: 65 kmh
Step-by-step explanation:
70 kmh for 2 hours = 140 km.
63 kmh for 5 hours = 315 km
140 + 315 = 455/7 total hours = 65 kmh
A person had $17,000 invested in to accounts One paying 7% simple interest And one paying 8% simple interest. How much was invested In each account if the interest rate after one year is $1356?
Answer:
A1 7% = $400 & A2 8% = $16,600
Step-by-step explanation:
A1 * 7% + A2 * 8% = 1356
A1 + A2 = 17000
A1 = 17000 - A2
(17000 - A2) * 0.07 + A2 * 0.08 = 1356
1190 - 0.07 A2 + 0.08 A2 = 1356
1190 + 0.01 A2 = 1356
0.01 A2 = 166
A2 = 16600
A1 = 17000 - A2
A1 = 17000 - 16600
A1 = 400

Determine whether each ordered pair is a solution to the inequality x+y>−2.
(10,−1)
(−8,9)
(−1,−9)
(6,−3)
(7,−9)
===================================
Explanation:
If we plug the coordinates of point A into the inequality, then we get
x+y > -2
10 + (-1) > -2
9 > -2
That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers
Choices B and D are also answers for similar reasons.
Something like choice C is not a solution because
x+y > -2
-1+(-9) > -2
-10 > -2
which is false
You should find that choice E is false as well.
---------------------
If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.
The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.
What’s the slope and equation
Answer:
slope = -5 equation= y=-5x+100
Step-by-step explanation:
pick the x and y intercepts as your points to find the gradient that is
(20,0) and (0,100)
slope =∆y/∆x
=100/-20
= -5
take point(20,0) and (x,y) to find equation using the slope
equation becomes y= -5x+100

The quotient obtained by dividing 4x²+3x+2 will be 4x + 15 hence option (A) will be correct.
What is the equation?An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraint.
Given that
dividend = 4x²+3x+2
divider = x -3
⇒ (x - 3) / 4x²+3x+2
⇒ (x - 3) / 4x²+3x+2
→ First it will goes for 4x time so 4x × (x - 3) = 4x² - 12x
Quotient = 4x
so (4x²+3x+2) - ( 4x² - 12x ) = 15x + 2
(x - 3) / 4x²+3x+2
→ Second time it goes for 15 so 15 × (x - 3) = 15x -45
Quotient = 15
so (15x + 2 ) - ( 15x -45 ) = 47
Hence, 47 will be the remainder and the quotient will be (4x + 15).

3 3/8- 9/8 give your answer as a mixed number
Answer:
2 1/4
Step-by-step explanation:
We have to make the first value into an improper fraction, which makes 3 3/8 into 27/8. Now we subtract 9 from 27, giving us 18. This 18 is still over the common denominator of 8. 8 goes into 18 twice with 2 left over. So we have our mixed number as 2 2/8, which can be simplified to 2 1/4.

find the y-cordinates of the points that are 10 units away from the point (7,6) that have a x-cordinate of -1
Answer:
y = {0 , 12}, x = -1
point 1 (-1, 0)
point 2 (-1, 12)
Step-by-step explanation:
use the distance formula
d² = (∆x)² + (∆y)²
-----------------------------
10 units away from the point (7,6)
x-cordinate of -1
10² = (-1 - 7)² + (y - 6)²
100 = 64 + (y - 6)²
Subtract 64 from both sides
36 = (y - 6)²
Take the square root of both sides
±6 = y - 6
Add 6 to both sides
y = {0 , 12}

suppose a hole of radius 1 is bored through a sphere of radius 2. what is the volume of the resulting shape
Answer:
21.77
Step-by-step explanation:
Applying,
V = (4/3)π(R²-r²)³/²................. Equation 1
Where V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie
From the question,
Given: R = 2, r = 1
Constant: π = 3.14
Substitute these values into equation 1
V = 4/3(3.14)(2²-1²)³/²
V = (12.56/3)(3)³/²
V = 4.19(5.196)
V = 21.77

In ΔGHI, h = 9.6 cm, g = 9.3 cm and ∠G=109°. Find all possible values of ∠H, to the nearest 10th of a degree.
The possible values of ∠H, to the nearest 10th of a degree 77.4 degrees
To get the possible values of m<H, we will use the sine rule as shown:
g/sin∠G = h/∠H
Given the following parameters:
h = 9.6 cm, g = 9.3 cm and:∠G=109°Substitute the given parameters into the formula to have:
9.3/sin109 = 9.6/sin∠H
9.3sin∠H = 9.6sin109

Jane Peterson has taken Amtrak to travel from New York to Washington, DC, on six occasions, of which three times the train was late. Therefore, Jane tells her friends that the probability that this train will arrive on time is 0.50. Would you label this probability as empirical or classical? Why would this probability not be accurate?
Answer:
a) This probability as empirical Probability.
b) This probability is not accurate because this experiment must be repeated a large number of times for empirical probabilities should be accurate.
Step-by-step explanation:
On 6 occasions, of which three times the train was late. that means 3 times the train is on time.
Empirical probability = Number of outcomes satisfying event / No.of trails
= 3/6 = 0.5.
a) This probability as empirical Probability.
b) This probability is not accurate because this experiment should be repeated a large number of times for empirical probabilities should be accurate.

What is the distance between the points (2, -3) and (-6, 4) on the coordinate
plane?
A. 4.12 units
B. 3.87 units
C. 10.63 units
D. 8.06 units
Answer:
C) 10.63 units.
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have the two points (2, -3) and (-6, 4). Let (2, -3) be (x₁, y₁) and let (-6, 4) be (x₂, y₂). Substitute:
[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]
Simplify:
[tex]d=\sqrt{(-8)^2+(7)^2}[/tex]
Evaluate:
[tex]d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}[/tex]
Our answer is C.
Consider an urn containing 4 white balls and 1 black ball, and suppose that balls will be sequentially drawn (without replacement) from the urn until the black ball is obtained. Letting X denote the number of white balls drawn before the black one is selected, give the pmf of X.
Answer:
[tex]P(X = 0) = 0.2[/tex]
[tex]P(X = 1) = 0.2[/tex]
[tex]P(X = 2) = 0.2[/tex]
[tex]P(X = 3) = 0.2[/tex]
[tex]P(X = 4) = 0.2[/tex]
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
pmf of X.
Probability of each outcome, 0, 1, 2, 3 or 4 white balls drawn.
Before the trials, you are equally as likely to get the black ball in the 1st trial(0 white balls drawn) to the 5th trial(4 white balls drawn). So this is an uniform distribution with [tex]P(X = x) = \frac{1}{5} = 0.2[/tex]
Thus, the pmf is:
[tex]P(X = 0) = 0.2[/tex]
[tex]P(X = 1) = 0.2[/tex]
[tex]P(X = 2) = 0.2[/tex]
[tex]P(X = 3) = 0.2[/tex]
[tex]P(X = 4) = 0.2[/tex]
