The answer is -8
when you put in -3 for x, you have to first multiply 2 and -3, and you get 6, then you subtract 2 and you get -8. There you go =)
Answer:
0
Step-by-step explanation:
Let X to be a random variable that looks a binomial distribution which denoted the number of employees out of the 281 who earn the prevailing minimum wage or less
The sample size n = 281
The population parameter p = 5% = 0.05
Using normal approximation for the mean.
The standard deviation is:
By using continuity correction; the sample mean x is:
x = 30 - 0.5
x = 29.5
The z statistic test can now be as follows:
Z = 4.23
Thus, the probability that company A will get a discount is
P(X ≥ 30) = P(Z >4.23)
= 1 - P(Z < 4.23)
By using the Excel function for the z score 4.23 i.e. "=1 - NORMSDIST(4.23)" we get;
= 0.0000
Answer:
The correct option is A) 13 to 3.
Step-by-step explanation:
Consider the provided information.
The pet store had 6 puppies selling for $104 each and 12 kittens selling for $24 each. Today, only 2 puppies and 8 kittens were left.
6-2 = 4 puppies sale
12-8 = 4 kittens sale
The cost of each puppies is $104.
Cost of 4 puppies:
4×$104=$416
The cost of each kittens is $24.
Cost of 4 kittens :
4×$24=$96
The ratio of sales of puppies to kittens is:
Hence, the ration of sales of puppies to kittens is 13/3.
Thus, the correct option is A) 13 to 3.
Answer:
302 cm²
Step-by-step explanation:
To find the surface area of the figure, find the area of each face and add them together.
<u>The cube</u>
There are 9 faces for the 2 cubes on top of the blue prism. Each face measures as 2cm by 2 cm. The area of one face is A = 2*2 = 4 cm². Since there are 9 faces, the surface area of the cubes is 9*4 = 36 cm².
<u>The rectangular prism</u>
There are 6 faces for the blue prism. Four of the faces measure 11 cm by 5 cm. Two of the faces measure 5cm by 5 cm. Find the area by multiplying each face's measurements.
11*5 = 55
Four faces: 4*55 = 220 cm²
5*5 = 25
Two faces: 2*25 = 50 cm²
All together the surface area of the figure is 36 + 220 + 50 = 306.
However notice that the cube sits on top of the blue prism and covers up a portion of the face. The area it covers is 4 cm². Subtract 306 - 4 = 302.
