A right triangle is displayed.

Mazyrski [523]

Answer:

You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

The trapezoid below has an area of 475 square meters.

OLga [1]

Data:
B (Larger base) = 28 m
b (Minor base) = 18 m
h (height) = ?
A (area) = 475 m²

Formula:
$A = \frac{(B+b)*h}{2}$

Substitute:
$475 = \frac{(28+18)*h}{2}$
$475 = \frac{\diagup\!\!\!\!\!46^{23}*h}{\diagup\!\!\!\!2^1}\:\:\to\:\:\:475 = 23*h\:\:or\:\:\boxed{\boxed{23h = 475}}$

Answer:
$\textcircled{ A } 23h = 475$

The length of a text message is conversation is normally distributed with a mean of 2 min and a standard deviation of 0.5 min.

Dmitry_Shevchenko [17]

$\mathbb P(X>3)=\mathbb P\left(\dfrac{X-2}{0.5}>\dfrac{3-2}{0.5}\right)=\mathbb P(Z>2)$

About 95% of a normal distribution lies within two standard deviations of the mean, so 5% lies without, and since the distribution is symmetric, 2.5% lies to either side. This means

$\mathbb P(X>3)=\mathbb P(Z>2)\approx0.025$
