Answer: The  experimental probability that she will roll an even number= \frac{1}{2}


Step-by-step explanation:

We know that the probability for any event is given by6;-

\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}

In a dice, the total even numbers (2,4,6)= 3

Therefore, the probability that she will roll an even number will be given by:-

\text{Probability}=\frac{\text{3}}{\text{6}}=\frac{1}{2}

Hence, The  experimental probability that she will roll an even number= \frac{1}{2}

Answer:  C) exactly one triangle

<u>Step-by-step explanation:</u>

Given: ∠A = 45°, ∠B = 65°, side c = 4 cm

By the Triangle Sum Theorem, ∠C = 70°

Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.

\dfrac{\sin\angle A}{a}=\dfrac{\sin\angle B}{b}=\dfrac{\sin\angle C}{c}\\\\\\\dfrac{\sin 45^o}{a}=\dfrac{\sin65^o}{b}=\dfrac{\sin70^o}{4}

Thus, there is exactly one triangle.

Skydiver is falling about 176 feet per second how many feet per minute
svlad2 [7]
1 minute has 60 seconds. So, we'll multiply the numerator and the denominator by 60.

176 feet/1 second = 10,560 feet/1 minute

You deposit $1,200.00 into an account and in three years of simple interest you have $1,380. What interest rate are you receivin
Tcecarenko [31]
Since simple interest doesn't involve compounding, the same amount gets added on every year. So, the equation for the simple interest received is I = Prt, where I is the total interest, P is the original deposit (or "principal"), r is the interest rate, and t is the time passed in years.

Plugging in our values, we can solve for the interest rate:

I = Prt
\$1380 - \$1200 = (\$1200)(r)(3 years)
\$180 = (\$1200)(r)(3 years)
r = .05 = \bf 5 \%

The value of x and the value of y
egoroff_w [7]

Answer:

x= 60 y=50

Step-by-step explanation:

First to find x, all the degrees in a triangle add up to 180 degrees. So 50+70+x=180 which is also 120+x=180 which means x=60. Y is the exterior angle of x and a missing angle. Let's substitute the missing angle with the variable z. 60+50+z=180 which is 110+z=180 which means z is 70. So 180-x+z=y. 180-60+70=y which means y is equal to 50. Hope this helps!
