The solution is, 600g of pasta cost £ 0.9.
Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
given that,
Pasta costs £1.50 per kg.
now we have to find,
How much does 600g of pasta cost
we know,
1 kg = 1000 grm.
so, we get,
1000 g Pasta costs £1.50
so, 1 g Pasta costs £1.50/1000
so, 600 g Pasta costs £1.50/1000 * 600
= £ 0.9
Hence, The solution is, 600g of pasta cost £ 0.9.

Answer:
y=6x-8
Step-by-step explanation:
10-4/3-2
m=6/1
y=mx+b
y=6x+b
4=6(2)+b
4=12+b
-8=b
y=6x-8
Let's organize our given information.
What I'd like to do is solve for first, it'll help later.
Now, we can differentiate our formula for the volume of a cylinder to find the rate of change of the radius.
Use the product rule of differentiation.
Plug in the information we are given.
Solve for .
The rate of change of the radius is -0.866 centimeters per minute.
Hope this helps!

Answer:
Step-by-step explanation:
Assuming this info from R
hist(gifted$count)
## Min. 1st Qu. Median Mean 3rd Qu. Max.
## 21.00 28.00 31.00 30.69 34.25 39.00
## Sd
## [1] 4.314887
Data given and notation
represent the mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the mean is different than 32, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
If we analyze the size for the sample is > 30 but we don't know the population deviation so is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
P-value
The first step is calculate the degrees of freedom, on this case:
Since is a two sided test the p value would be:
Order is operation is PEMDAS which means Parentheses, Exponents Mulitiplication,division,Addition and Subtraction so you follow the order whether they exist or not.
So (41-3^2)-(4+4)=
41-9-8 = 32-8 = 24
