Answer:

The correct option is;

D. The given measures create two triangles because bsinA < a < b.

Step-by-step explanation:

Here we have the law of sines given by

$\frac{sinA}{a} = \frac{sin B}{b} = \frac{sin C}{c}$

Let A = 50°

a = 14 units

b = 16 units

Since the b·sinA = 16··sin50 = 12.3 < 14 < a < b

Therefore either B < A or B < A are two possible triangles formed by the sides and the subtended angle to the short side

The short side can meet the base (the third side with no length dimension) at two points, forming two different triangles.

Answer:

1. $x=3$

2. $1$

3. $x=11$

Step-by-step explanation:

$1.\\\frac{x}{5}=\frac{12}{20}\\\\x=3\\\\\\2.\\-1\frac{3}{5}*(-\frac{5}{8})=\\\\-\frac{8}{5}*(-\frac{5}{8})=\\\\-(-\frac{40}{40})=\\\\-(-1)=\\\\1\\\\\\3.\\\frac{x}{14}=\frac{55}{70}\\\\x=11$

Help with this question(Will give brianlist and thanks)(Determine the area)

lana [24]

Answer:

The area of trapezium is (x+11) cm².

Step-by-step explanation:

Given that the formula of area of trapezium is :

$area = \frac{1}{2} \times (a + b) \times h$

In the formula, a and b represents the length of trapezium and h is the height. So you have to substitute the following expressions into the formula :

$let \: a = 5 \\ let \: b = x + 6 \\ let \: h = 2$

$area = \frac{1}{2} \times (5 + x + 6) \times 2$

$area = \frac{1}{2} \times 2 \times (x + 11)$

$area = 1 \times (x + 11)$

$area = (x + 11) \: {cm}^{2}$

avanturin [10]

Answer:

The result is significant.

Step-by-step explanation:

Here,

p = 30 ÷ 330 = 0.091

thus, q = 1 - p = 0.909

Also, $\sigma=\sqrt{\frac{pq}{n} }$

⇒ $\sigma=\sqrt{\frac{0.091\times0.909}{330} }=0.0158$

The z-score is:

$z=\frac{p-p_{0}}{\sigma}$

$z=\frac{0.091-0.05}{0.0158}=2.595$

Thus, at 95% confidence interval, p-value = 0.005

The result is significant at p < .05.

ch4aika [34]

To work this out, you have to figure out how much Salid paid. This equals $61.25 as you have to multiply the cost and how much he wanted. Next, you have to subtract this from $100. This equals $38.75 (answer)
I hope this helped!! :))
