Answer:

0.425

Step-by-step explanation:

Given that there are 4 mint biscuits and 1 toffee biscuit in a tin and 5 mint sweets and 3 strawberry sweets in a packet.

So, the total number of biscuit in tin = 4+1= 5 and

Number of mint biscuit in tin = 4

Number of toffee biscuit in tin = 1

So, the probability of picking 1 mint biscuit from tin,

[tex]p_1[/tex]=(Number of mint biscuit in tin)/(Total number of biscuit in the tin)

[tex]\Rightarrow p_1 =4/5 = 0.8[/tex]

The probability of picking 1 toffee biscuit from tin,

[tex]p_2[/tex] =(Number of toffee biscuit in tin)/(Total number of biscuit in the tin)

[tex]\Rightarrow p_2=1/5 = 0.2[/tex]

Similarly, the total number of sweets in the basket = 5+3=8 and

Number of mint sweets  in the basket = 5

Number of strawberry sweets  in the basket = 3

So, the probability of picking 1 mint sweets from the basket,

[tex]p_3[/tex] =(Number of mint sweets  in the basket)/(Total number of sweets  in the basket)

[tex]\Rightarrow p_3=5/8 = 0.625[/tex]

The probability of picking 1 strawberry sweets from the basket

[tex]p_4[/tex] =(Number of strawberry sweets  in the basket)/(Total number of sweets  in the basket)

[tex]\Rightarrow p_4=3/8 = 0.375[/tex]

As Michael takes a biscuit from the tin as well as a sweet from the packet randomly, so the possible combinations can be

A) 1 mint biscuit and 1 mint sweets,

B) 1 toffee biscuit and 1 strawberry sweets,

C) 1 mint biscuit and 1 strawberry sweets, and

D) 1 mint sweets and 1 toffee biscuit.

Here, (C) and (D) are the desired case of either the biscuit is mint, but not both.

So, the probability of either the biscuit is mint, but not both

= Probability of ( 1 mint biscuit and 1 strawberry sweets) or (1 mint sweets and 1 toffee biscuit)

[tex]=p_1 \times p_4 + p_2\times p_3 \\\\=0.8 \times 0.375 + 0.2\times 0.625 \\\\=0.425[/tex]

Hence, the probability of either the biscuit is mint, but not both is 0.425

Answer:

m < 4

Step-by-step explanation:

Given

2m + 6 > 7(m - 2) ← distribute

2m + 6 > 7m - 14 ( subtract 2m from both sides )

6 > 5m - 14 ( add 14 to both sides )

20 > 5m ( divide both sides by 5 )

4 > m , thus

m < 4

Answer:

For number 2, its A. For number 1, its C.

Step-by-step explanation:

For both equations, you just set it equal to to each other because alternate interior angles are equivalent.

2) The equation would be

     7x+3=6x+12

   Then solve.

1) The equation would be

     14x-3=95

   Then solve.

Using compound interest, it is found that it would take 11 years for the value of the account to reach $70,900.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

Hence, the parameters are given as follows:

[tex]A(t) = 70900, P = 37000, n = 365, r = 0.057[/tex]

We have to solve for t, then:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]70900 = 37000\left(1 + \frac{0.057}{365}\right)^{365t}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = \frac{70900}{37000}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = 1.91621622[/tex]

[tex](1.00015616)^{365t} = 1.91621622[/tex]

[tex]\log{(1.00015616)^{365t}} = \log{1.91621622}[/tex]

[tex]365t\log{1.00015616} = \log{1.91621622}[/tex]

[tex]t = \frac{\log{1.91621622}}{365\log{1.00015616}}[/tex]

t = 11.41

Rounding to the nearest year, it would take 11 years for the value of the account to reach $70,900.

Step-by-step explanation:

8 books

If melissa's table holds up to 200 pounds, and she has books weighing 24.5 pounds, we need to know how many times 24.5 can go into 200

200/24.4 ≈ 8.196...

However, because we aren't going to cut up the books into that remaining fraction all we care about is the whole number 8 and not the decimal of .196...

So, melissa can fit 8 books on that table. However, I wonder if the book's binding is made of metal because those are some heavy books.

Hope this helps :)

The number of books Melissa's table can hold is 8 books

Number of books Melissa's table can hold = Pounds of books Melissa's table can hold ÷ Pounds of each book

= 200 / 24.5

= 8.16326530612244

Approximately,

8 books

Answer:

(1, 3 )

Step-by-step explanation:

To find a solution choose a value for x, substitute into the equation and solve for y.

let x = 1 , then

- 7(1) + 3y = 2 , that is

- 7 + 3y = 2 ( add 7 to both sides )

3y = 9 ( divide both sides by 3 )

y = 3

One possible solution is therefore (1, 3 )
