Answers

Answer 1

Answer:

A

Step-by-step explanation:

We are given that:

[tex]\tan(\theta)=1.3[/tex]

And we want to find:

[tex]\cot(90^\circ -\theta)[/tex]

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:

[tex]\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)[/tex]

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.

Our answer is A.

16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean

Answers

Answer:

70.06

Mean score = 70

Step-by-step explanation:

16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean

For a normal distribution :

Zscore = (x - mean) / standard deviation

x = score

P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)

Therefore ;

0.994 = (80 - mean) / 10

0.994 * 10 = 80 - mean

9.94 = 80 - mean

Mean = 80 - 9.94

Mean = 70.06

Hence, the mean score = 70.06 = 70

Work out the size of angle x.

Answers

Answer:

x = 66

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 79 + 35 = 180

x + 114 = 180

x = 180 - 114

x = 66

Answer:

66°

Step-by-step explanation:

Since the sum off all the angles of a triangle is 180°,

x + 79° + 35° = 180°

x + 114° = 180°

x = 180° - 114° = 66°

Therefore, x = 66°

Moe painted the lid of the barrel. The circumference of the barrel is 32*3.14 inches. What is the area of the lid in square inches?

Answers

Answer: 803.84 inch²

Step-by-step explanation:

The lid will take the appearance of a circle so the area of the lid is the same as the area of a circle:

Area of a circle = π * radius²

The circumference of a circle is:

= π * diameter

Looking at the above, the diameter is 32inches because this is the figure to be multiplied with π = 3.14 to find the circumference.

Since diameter is 32, radius will be:

= 32 / 2

= 16 inches

Area = 3.14 * 16 * 16

= 803.84 inch²

Answer: 37/12

Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.
