9: 1/36 chance of getting the same number on both dice
10: a) 5 b) 4/25
Explanation:
9: a die has 6 sides with each number. So the chance of getting a number on a dice once is 1/6. The second dice is the same with 1/6 chance. But to have them both be the same number means you have to multiply the probability. (1/6)/(1/6)=1/36
10:
a) 1/4 of the discs are blue, meaning you have multiply 1/4 by 20 which equals 5
b) the probability of getting a red is 12/20. So the probability of not getting red is 8/20. But both simultaneously, would mean for multiplying them. 8/20 •8/20=64/400 Then simplified to 4/50.

On her first day in a hospital, Kiri receives u1 milligrams (mg) of a therapeutic drug. The amount of the drug Kiri receives increases by the same amount, d, each day. On the seventh day, she receives 21 mg of the drug, and on the eleventh day she receives 29 mg.
a. write down an equation, in the terms u1 and d, for the amount of the drug that she receives on the seventh day.
b. write down an equation, in terms of u1 and d, for the drug that she receives on the eleventh day.
c. write down the value of d and the value of u1.
Answers
Answer:
a. 21 = u1 + 6·d
b. 29 = u1 + 10·d
c. d = 2, u1 = 9
Step-by-step explanation:
a. The given parameters are;
The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams
The amount of drug increase received by Kiri each day = d
The amount of drug Kiri received on the seventh day = 21 mg
The amount of drug she received on the eleventh day = 29 mg
Therefore, we have an arithmetic progression with the formula for the nth term given as follows;
aₙ = a₁ + (n - 1)·d
Where;
a₁ = u1
n = The number of terms
Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;
a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21
The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;
21 = u1 + 6·d
b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;
a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29
Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the eleventh day is given as follows;
29 = u1 + 10·d
c. Therefore, we have two equations which are given as follows;
21 = u1 + 6·d................(1)
29 = u1 + 10·d..............(2)
Subtracting equation (1) from equation (2) gives;
29 - 21 = (u1 + 10·d) - (u1 + 6·d)
8 = 4·d
d = 8/4 = 2
d = 2
From equation (1), we have;
21 = u1 + 6·d = u1 + 6×2 = u1 + 12
21 = u1 + 12
21 - 12 = u1
∴ u1 = 9
d = 2, u1 = 9.

Step-by-step explanation: this is correct, pls mark brainliest. take -4 and add it to the other side(+4). 6x=3x+8. subtract 3x from 6x. 3x=8. take 3x and devide it on bolth sides. x=2.666 repeated
Answer:
x = 3/8
Step-by-step explanation:
6x -4 = 3x + 4
Step 1 - Add 4 on both sides
6x -4 = 3x + 4
+ 4 + 4
6x = 3x + 8
Step 2 - Subtract 3x on both sides
6x = 3x + 8
-3x -3x
3x = 8
Step 3 - Divide 3 on both sides

What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2,1)?
Answers
Answer:
y=5x+11
Step-by-step explanation:
You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.
First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.
Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.
y-(1)=5(x+2)
y-1=5x+10
y=5x+11
Check:
(1)=5(-2)+11
1=-10+11
1=1

The ratio of books
to magazines in the
children's section at the
library is 5-2. If there
are 225 books, calculate
the number of
magazines.
Answers
50 magazines
because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50
There are 64 magazines in the library.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
The ratio of books to magazines in the children's section at the library is 5: 2.
Let number of books = 5x
And, Number of magazines = 2x
Here, There are 225 books in the library.
Hence, We can formulate;
⇒ 5x + 2x = 225
⇒ 7x = 225
⇒ x = 32
Hence, Number of magazines = 2x
= 2 × 32
= 64

It costs a flat rate of $35 for you to rent the ovens for as many hours as you want. You charge $29 per birthday cake. Your total costs is $470. Write and solve an equation to find how many birthday cakes were made.
Answers
470 = 29x+35
(x is number of birthday cakes)
subtract 35 from both sides,
435 = 29x
divide both sides by 29 to get x by itself,
15 = x
15 birthday cakes were made!
Answer:
35+29x=470 x=15 cakes
