I used a tutor for this and the answer I was given is 17.5. Which is incorrect. I am trying to understand how to solve.​

Answer:

He made 36 free throws out of 180

Given:

The given equation is

[tex]x^2-8x+16=0[/tex]

To find:

The correct statement for the given equation.

Solution:

We have,

[tex]x^2-8x+16=0[/tex]

It can be written as

[tex]x^2-2(x)(4)+(4)^2=0[/tex]

Using the identity of perfect square trinomial, we get

[tex](x-4)^2=0[/tex]            [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex](x-4)=0[/tex]

[tex]x=4[/tex]

Here, x=4 has multiplicity two because the power of factor (x-4) is 2.

x=4 is a double root and the equation is a perfect trinomial.

Therefore, the correct options are C and E.

Answer:

B) Factor to solve.

C) x = 4 is a double root.

E) The equation is a perfect square trinomial.

Step-by-step explanation:

Factor to solve.<

By inspection, the equation is a perfect square trinomial.

x = 4 is a double root

By inspection, the middle term's coefficient 8 is twice the square root of 16, the constant; therefore, it is a perfect square trinomial.

x2 − 8x + 16 = 0 → (x − 4)(x − 4) = 0 → x = 4 is a double root.

Answer:

Small bag: £7.20 for 3 kg

Medium bag: £7.80 for 3 kg

Best value: small bag

Step-by-step explanation:

3 kg = 3000 g

Small bag: 60p/250 g = 0.24p/g

For 3000 g: 0.24p/g * 3000 g = £7.20

Medium bag: £1.30/500 g = 0.0026 £/g

For 3000 g: 0.0026 £/g * 3000 g = £7.80

Large bag:

For 3000 g: £7.50

Best value: small bag

Answer:

If they won 90 out of 162, they won 55.(5)% of their games.

Step-by-step explanation:

I assume they WON 90 of the 162 games.

90/162 = 45/81 = 15/27 = 5/9

5/9 = 55.(5)%; (because 1/9 = 11.(1)%)

Answer:

55.56%

Step-by-step explanation:

1. Put into a fraction = 90/162

2. Simplify = 5/9

3. Calculate the fractions value by dividing the numerator by the denominator.

4. Multiply the answer by 100

5. Simplify

Answer: D, C, A

Step-by-step explanation:

An exterior angle is an angle that is supplementary to an interior angle.

The angle between the extended side and its adjacent side is called the exterior angle so the option (D), (C), and (A) will be the correct answers.

Exterior angles become by a side of that figure and its extended adjacent side.

The exterior angle has been attached.

Since in the graph angle, ∠3 become by two extended lines but for exterior angle, there should be only one extended line which is ∠6, ∠5, and ∠2.

Hence angles ∠6, ∠5, and ∠2 will be the exterior angles.

Answer:

The number of people who like winter season is 1000.

Step-by-step explanation:

Event event correspond to a set in the Venn diagram, and we use it to find the percentages.

I am going to say that:

Event A: Like summer season

Event B: Like winter season.

55% like summer season

This means that [tex]P(A) = 0.55[/tex]

20% like winter season

This means that [tex]P(B) = 0.2[/tex]

40% don't like both seasons

This means that 100% - 40% = 60% like at least one, which means that [tex]P(A \cup B) = 0.6[/tex]

Proportion who like both:

This is [tex]P(A \cap B)[/tex]. The measures are related by the following equation:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

Using what we have

[tex]P(A \cap B) = 0.55 + 0.2 - 0.6 = 0.15[/tex]

750 like both seasons.

This is 15% of the sample. So the total number of people is t, for which:

[tex]0.15t = 750[/tex]

[tex]t = \frac{750}{0.15}[/tex]

[tex]t = 5000[/tex]

20% like winter season

Out of 5000. So

0.2*5000 = 1000

The number of people who like winter season is 1000.

Remark

The diagonal is found by using the Pythagorean Theorem: a^2 + b^2 = c^2. This only works for certain figures. The rectangle is one of them.

Givens

a = 10

b = 8

c = ?   This is the length of the diagonal.

Solution

a^2 + b^2 = c^2

10^2 + 8^  = c^2

100 + 64 = c^2

c^2 = 164

√c^2 = √164

c = 12.806
