Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is y2-y1/x2-x1
= 10/1/ 3-0
= 9/3
= 3.
Using the point-slope form for a straight line:
y-y1 = m(x-x1) (m = slope)
y - 10 = 3(x - 3)
y - 10 = 3x - 9
y = 3x - 9 + 10
y = 3x + 1 is the required equation.

An A grade will be given to students having at least 370 total test points. There is one more test to take before the semester is over. Lesha wants to know what she needs to score on the next test to finish with an A. Write and solve an equation to determine what score she needs to get. Explain your reasoning.
Answer:
95 points
Step-by-step explanation:
Given
[tex]n = 370[/tex] --- expected point
See attachment for points
Required
An inequality to determine the points needed
First, we calculate the points (p) Lesha has already accumulated.
[tex]p = Test\ 1 + Test\ 2 + Test\ 3[/tex]
[tex]p = 75 + 100 + 100[/tex]
[tex]p = 275[/tex]
Let the number of points needed be t.
So:
[tex]p + t = 370[/tex] ---- i.e. She must score a total of 370
Make t the subject
[tex]t = 370 -p[/tex]
Substitute 275 for p
[tex]t = 370 -275[/tex]
[tex]t = 95[/tex]

Aaron, Bonny and Connor are playing a game with cards.
Aaron has some cards.
Bonny has twice as many cards as Aaron.
Connor has 6 cards more than Bonny.
They have a total of 101 cards.
Work out how many cards Aaron has.
Let the number of cards Aaron has : A
Given :
⊕ Bonny has twice as many cards as Aaron
⊕ Connor has 6 cards more than Bonny
⊕ Total cards : 101
⇒ Number of cards Bonny has : 2A
⇒ Number of cards Connor has : 2A + 6
⇒ Aaron cards + Bonny cards + Connor cards = 101
⇒ A + 2A + 2A + 6 = 101
⇒ 5A = 101 - 6
⇒ 5A = 95
⇒ A = 19
Answer : Aaron has 19 Cards

Round 8.157 to the nearest hundredth.
Answer:
I believe the answer is 8.16 pardon me if it's wrong.
Answer:
8.18
Step-by-step explanation:
First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 8
Fractional Part: 175
To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.
We use the following rules to round 8.175 to the nearest hundredth:
A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.
B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

Caculate the temperature change if 3456 J of thermal energy was transferred into 3.0 kg of lead? The specific heat of lead is 128 J/kgo C.
Answer:
9°C
Step-by-step explanation:
quantity of heat energy absorbed is expressed as;
Q = mcΔt
m is the mass
c is the specific heat capacity
Δt is the change in temperature
Substitute the given values
3456 = 3 * 128 Δt
3456 = 384Δt
Δt = 3456/384
Δt = 9°C
Hence the temperature change is 9°C

A sphere fits inside a cube with the sphere's diameter equal to the width of the cube, 20 centimeters. What is the volume of the cube not filled by the sphere? Round to the nearest cm³
A) 3813cm³
B) 3225cm³
C) 4079cm³
D) 3546cm³
The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.
What is volume?The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.
The volume of sphere is found as;;
[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]
The volume of cube is found as;
Volume of cube = Length x width x height
Volume of cube =20 x 20 x 20
Volume of cube = 8000
The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.
V=8000 - 4188.790205
V = 3811.209
The volume of the cube not filled by the sphere is 3811.209.
Hence, option A is the correct.

Answer:126m2
Step-by-step explanation:
Since they are both rectangles, use the area of a rectangle equation to find it which is length times width. What I would do first is find the area of the big rectangle which is 10*15 which is 150. Then I would find the area of the white space which is 6*4 which is 24. Since the white space is not part of the question, subtract 24 from 150 which gets you 126m2. Hope this helps :)

A drug company conducts trials of a new vaccine for a rare but usually fatal disease. The company creates a
geometric model for this trial and establishes p=0.2 as the probability of success.
What can be said about this model?
Select all that apply.
1)The company predicts 4 failures before a success.
2)Each trial is independent.
3)The probability is the same for each trial.
4)The probability that the vaccine will be effective is p = 0.8.
5)Success is defined as preventing the disease.
6)The company predicts 8 failures before a success.
7)Success is defined as p = 0.2.
Answer:
What can be said about the model are;
1) The company predicts 4 failures before success
2) Each trial is independent
3) The probability is the same for each trial
4) Success is defined as preventing the disease
Step-by-step explanation:
The probability of success for the vaccine, p = 0.2
Therefore, the probability that the vaccine is effective and prevents the disease = 0.2
A geometric distribution probability of success is given by the following formula;
P(X = x) = p × q⁽ˣ⁻¹⁾
The expected value, E(Y) = 1/p
The number of failures before success, E(Y) = (1 - p)/p = (1 - 0.2)/0.2 = 4
Where;
q = The probability of a trial failing = 1 - p = 1 - 0.2 = 0.8
q = 1 - p
∴ The e
The geometric model criteria are;
a) Each trial can only have one of two outcomes success or failure
b) The probability of success for each trial is fixed
c) The geometric distribution is concerned with finding how many trials are required to get one success
d) The trials are independent
Therefore, we have;
The number of failures the company predicts before a success = 4 failures
2) The trials are independent
3) Each trial has an equal probability
4) Success is defined by the effectiveness of the vaccine in the prevention of the disease
