Question 1 1.1 Jane wants to make Spaghetti Bolognese for her family of 5 people, including herself. The following is a list of

Lelechka [254]

Answer:

$\begin{gathered} 1.1.1.300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg} \\ 1.1.2.400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg} \\ 1.1.3.500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt} \\ 1.1.4.769.69\cdot0.001=0.769\text{ liters} \end{gathered}$

Step by step explanation:

1.1.1 We know that 1kg is equivalent to 1000g, then we can convert:

$300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg}$

1.1.2 For 400g of tomatoes:

$400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg}$

1.1.3. For 500ml of water, convert this into liters. We know that a 1ml is 0.001 lt

$500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt}$

1.1.4. Since capacity is represented by the following expression:

$\begin{gathered} C=\pi\cdot\text{radius}\cdot\text{radius}\cdot\text{height} \\ C=\pi\cdot7\cdot7\cdot5=769.69cm^3 \end{gathered}$

We know that 1 cubic centimeter is equal to 0.001 liters.

$769.69\cdot0.001=0.769\text{ liters}$

The data below show the wins (W) and losses (L) for a basketball team over 25 consecutive games.

kotykmax [81]

Answer:

0.48 or 48%

Step-by-step explanation:

The relative frequency of wins for the basketball team in question is given by the number of wins over the course of the 25 games, divided by the total number of games.

Observing the given data, 12 'Ws' can be counted, which means that the relative frequency of wins is:

$F_W=\frac{12}{25}\\F_W=0.48$

The relative frequency of wins is 0.48 or 48%.

Consider the cubic function f(x) = x^3 + ax^2 + bx + 4 where (a) and (b) are constants. When f(x) is divided by x-3, the remaind

Debora [2.8K]

Answer:

see explanation

Step-by-step explanation:

Using the Remainder theorem

If f(x) is divided by (x - h) then f(h) = remainder, thus

f(3) = 3³ + a(3)² + b(3) + 4 = 10, that is

27 + 9a + 3b + 4 = 10

9a + 3b + 31 = 10 ( subtract 31 from both sides )

9a + 3b = - 21 → (1)

f(- 1) = (- 1)³ + a(- 1)² + b(- 1) + 4 = 6, that is

- 1 + a - b + 4 = 6

a - b + 3 = 6 ( subtract 3 from both sides )

a - b = 3 → (2)

Rearrange (2) expressing a in terms of b

a = 3 + b → (3)

Substitute a = 3 + b into (1)

9(3 + b) + 3b = - 21 ← distribute and simplify left side

27 + 9b + 3b = - 21

12b + 27 = - 21 ( subtract 27 from both sides )

12b = - 48 ( divide both sides by 12 )

b = - 4

Substitute b = - 4 into (3)

a = 3 - 4 = - 1

Hence a = - 1 and b = - 4
