Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°
Answer:
C. 0.403
Step-by-step explanation:
Binomial distribution has two parameter n and p. Here, n=15 and p=0.60.
We have to find the probability of 10 or more will show that the hamburger, French fries and a drink were ordered. P(X≥10)=?
The binomial probability distribution function for random variable X is

where q=1-p=1-0.6=0.4,n=15 and p=0.6.
P(X≥10)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)
=0.185938
=0.126776
=0.063388
=0.021942
=0.004702
=0.000470
P(X≥10)= 0.185938
+0.126776
+0.063388
+0.021942
+0.004702
+0.000470
P(X≥10)=0.403216
So, the probability of 10 or more will show that the hamburger, French fries and a drink were ordered is 0.403.
The third option is how you find the average
Answer:
The dryer costs $350
Step-by-step explanation:
<u>Step 1: Make a system of equations</u>
<em>w + d = 652</em>
<em>w = d - 48</em>
<em />
<u>Step 2: Plug in the know w into the first equation</u>
d - 48 + d = 652
2d - 48 + 48 = 652 + 48
2d / 2 = 700 / 2
<em>d = 350</em>
<em />
Answer: The dryer costs $350
Answer:
17
Step-by-step explanation:
first write the equation:
twice a number x is 2x
six less is -6
so equation is 2x - 6 = 38
solve for x:
2x = 34
x = 17
