Step-by-step explanation:

Because <2 and <4 are alternate angles

Answer:

∠2 = 35°

Step-by-step explanation:

∠4 and ∠2 are Alternate Interior Angles. This means that they will be congruent. As we know that ∠4 = 35°, ∠2 must also be 35°

How tall is the tower? 48° 16 ft -30 ft [?] ft Round to the nearest tenth.

Marina86 [1]

Answer:

49.3 ft

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan48° = $\frac{opposite}{adjacent}$ = $\frac{x}{30}$ ( multiply both sides by 30 )

30 × tan48° = x , then

x ≈ 33.3

Height of tower = 33.3 + 16 = 49.3 ft ( to the nearest tenth )

The hypotenuse of a right triangle is 15 inches. One of the legs is 3 inches more than the other. Find the length of the two leg

Crank

Let x = one of the legs.

Then, the other leg = x + 3.

Ed will use the Pythagorean Theorem to find the hypotenuse.

So, let a = x one leg. Let b= x + 3 the other leg. And, let c = 15 the hypotenuse.

The Pythagorean Theorem is:

c^2 = a^2 + b^2, where a and b are the legs and c is the hypotenuse.

We have:

15^2 = x^2 + (x + 3)^2

225 = x^2 + x^2 + 6x + 9

Rearranging:

2x^2 + 6x - 216 = 0

Divide by 2:

x^2 + 3x - 108 = 0

Solve by factoring:

(x - 9)(x + 12) = 0

So, x = 9 and x = -12. (x = -12 is not a valid answer.)

x = 9

x + 3 = 12

Conclusion: The legs of the right triangle are 9 inches and 12 inches.

Which decimal is equivalent to 8%

Nikitich [7]

Answer:

$0.08$

Step-by-step explanation:

Given : 8%

To find the decimal value of the percentage number

Remove the percentage symbol with 100 in the denominator

gives

$\frac{8}{100}\\$

Now taking the numerator to the decimal place equal to the number of zeros in the denominator or simply divide denominator with numerator.

Gives = $0.08$

So, the decimal equivalent of the given value is $0.08$

If we sample from a small finite population without replacement, the binomial distribution should not be used because the events

liraira [26]

Answer:

0.0008

Step-by-step explanation:

The formula for a hypergeometric probability is

$\frac{(_AC_x)(_BC_{n-x})}{_NC_n}$

where N is the population, A is the number of objects of type A, B is the number of objects of type B, n is the sample size and x is the number of successes.

In this problem, N is 13. A is 5, since there are 5 objects drawn, and B is 8, since there are 8 remaining objects.

The sample size, n, is 5, and x is 5:

$\frac{(_5C_5)(_8C_0)}{_{13}C_5}\\\\=\frac{1(1)}{1287}=\frac{1}{1287}\approx 0.0008$
