Ed buys a box of eggs costing £2.10, two packs of bacon for £2.90 each and two tins of baked beans. He pays with a £10 note and gets 70p change. How much does a tin of beans cost in pounds, £?

Answer: Actually, you must use the Pythagorean Theorem!

a squared plus b squared equals c squared. So if you substitute in the values, a is 2 units and b is three units. 2 squared is 4 and 3 squared is 9.

4 + 9 = 13 so the answer is the square root of 13. (√13)

Answer:

We conclude that:

[tex]25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex]

Step-by-step explanation:

Given the expression

[tex]25a^2-0.01b^{10}[/tex]

Rewrite [tex]25a^2-0.01b^{10}[/tex] as [tex]\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2[/tex]

so

[tex]25a^2-0.01b^{10}=\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2[/tex]

Apply difference of two squares formulas:

[tex]x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]

so

[tex]\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2=\left(5a+\sqrt{0.01}b^5\right)\left(5a-\sqrt{0.01}b^5\right)[/tex]

                               [tex]=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex]    ∵ [tex]\sqrt{0.01}=0.1[/tex],

Therefore, we conclude that:

[tex]25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex]

Answer:

840 ways

Step-by-step explanation:

From the above question, we are told that order matters, hence, to solve the above question, we use the Permutation formula.

P(n, r) = nPr = n!/(n -r)!

From the above question,

Since Jose is included in the 8 people and he takes the first seat

n = 8 - 1 = 7 people

r = 5 - 1 = 4 seats

This is because, once Jose takes the first seat, there are 4 seats left with 7 people waiting to be seated

Hence,

7P4 = 7!/(7 - 4)!

7P4 = 7!/3!

7P4 = 5040/6

7P4 = 840 ways

The correct factorization would be equal to [tex](a^2 - 3)(a^2 - 3)[/tex].

To express the expression [tex]a^4 - 3a^2 + 9[/tex] as a product of two monic quadratics with integer coefficients, we can start by factoring it using the difference of squares formula. Let's break it down step by step:

[tex]a^4 - 3a^2 + 9[/tex]

We can rewrite the expression as:

[tex](a^2)^2 - 3(a^2) + 3^2[/tex]

Now, the difference of squares formula:

[tex](a^2 - 3)^2[/tex]

So, the expression can be factored as the square of the binomial [tex](a^2 - 3)[/tex].

Therefore, the correct factorization is [tex](a^2 - 3)(a^2 - 3)[/tex].

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

Using the formula  to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

For example, let the points be

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 4)

Determining the slope between

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 1]

               = 2 / 2

               = 1

Thus,

The slope of the line between the points (1, 2)  and (3, 4)  will be: m = 1

Answer:

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

(-0.1740 , 0.1672)

Step-by-step explanation:

Step(i):-

Given A survey found that 31 of 60 randomly selected women

First sample proportion

                [tex]p_{1} = \frac{x_{1} }{n_{1} } = \frac{31}{60} = 0.5166[/tex]

Second sample proportion

               [tex]p_{2} = \frac{x_{2} }{n_{2} } = \frac{38}{73} = 0.520[/tex]

Level of significance = 0.05

Z₀.₀₅ = 1.96

Step(ii):-

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

[tex]((p_{1} ^{-}-p^{-} _{2} - Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ), (p_{1} ^{-}-p^{-} _{2} +Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ))[/tex]

where

[tex]Se(p_{1} - p_{2} ) = \sqrt{\frac{p_{1} (1-p_{1} )}{n_{1} }+\frac{p_{2}(1-p_{2} }{n_{2} } }[/tex]

[tex]Se(p_{1} - p_{2} ) = \sqrt{\frac{0.5166 (1-0.5166 )}{60 }+\frac{0.520(1-0.520 }{73 } } = 0.08706[/tex]

95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program

Juan and Ari went to the farmers market to buy fruit. Juan’s bag of apples that he bought weighed 31/7 pounds. Ari’s bag of oranges that she bought weighed 19/3 pounds. Using compatible fractions, estimate how much heavier Ari's bag is compared to Juan's bag.

A) 1 and one-half pounds

B) 2 pounds

C) 6 pounds

D) 10 and one-half pounds

Answer:

B: approximately 2 pounds

Step-by-step explanation:

Juan’s bag weighed 31/7 pounds

Ari's bag weighed 19/3 pounds.

We are told to use compatible fractions to determine the difference. Thus we have to make sure the denominator is the same;

For Juan, let's multiply both numerator and denominator by 3 to get; 93/21 pounds

For Ari, let's multiply both numerator and denominator by 7 to get; 133/21

Thus, difference is;

(133/21) - (93/21) = 40/21

This gives;

1.9 pounds heavier

This is approximately 2 pounds

B. 2 pounds

Answer:

P( 7 doughnuts or hot chocolate)=0.40

Step-by-step explanation:

From the question we are told that

Total number of plates [tex]n=10[/tex]

1)Generally the probability that you get 7 doughnuts and hot chocolate is mathematically given as

7 doughnuts and hot chocolate= 1 slot

Therefore

P( 7 doughnuts and hot chocolate)= 1/10

P( 7 doughnuts and hot chocolate)= 0.10

2)Generally the probability that you get 7 doughnuts or hot chocolate is mathematically given as

P( 7 doughnuts or hot chocolate)=P(7 doughnuts)+P(hot chocolate)-P( 7 doughnuts and hot chocolate)

1 plates contains 7 doughnuts

P(7 doughnuts)=1/10

P(7 doughnuts)=0.10

4 plates contain hot chocolate

P(hot chocolate)=4/10

P(hot chocolate)=0.4

7 doughnuts and hot chocolate= 1 slot

P( 7 doughnuts and hot chocolate)= 1/10

P( 7 doughnuts and hot chocolate)= 0.10

Therefore

P( 7 doughnuts or hot chocolate)=0.10+0.4-0.10

Therefore

P( 7 doughnuts or hot chocolate)=0.40

The probability of getting 7 doughnuts or hot chocolate is 0.4

Step-by-step explanation:

[tex](x + 40) \degree = (150 - x) \degree \\ (vertical \: \angle s) \\ \\ x + 40 = 150 - x \\ \\ x + x = 150 - 40 \\ \\ 2x = 110 \\ \\ x = \frac{110}{2} \\ \\ x = 55[/tex]

Answer:

x = 55°

Answer:

6.5%

Step-by-step explanation:

Percentage error formula =

|Estimated value - Real value|/Real value × 100

From the above question,

Estimated value = 17,466

Real value = 16,400

Percentage error = |17,466 - 16,400|/16,400 × 100

= 1066/16,400 × 100

= 0.065 × 100

= 6.5%

Therefore, the percent error = 6.5%

Answer: 6.5%

Step-by-step explanation: 17,466 - 16,400 = 1,066 (the difference)

16,400 / 16,400 = 1 • 100 = 100

1,066 / 16,400 = 0.065 • 100 = 6.5
