Answer:

See below.

Step-by-step explanation:

The standard deviation  =  √  (∑(x - 10)^2 / 8 )  must be approximately = 1 if we take the mean to be 10.

This requires ∑ (x - 10)^2 to be approximately equal to 8.

The following  data set would fit the bill:

8.6  9  9  10 10  11  11  11.5.

The values of (x - 10)^2  could be 1.96, 1, 1, 0,0, 1, 1, 2.25 = 8.21

This would give a mean of about 10 and standard deviation of about 1.

KATRIN_1 [288]

Answer:

$5,500

Step-by-step explanation:

Since Landen Company uses a single overhead rate of $100 per direct labor hour, the total amount allocated to the deluxe and basic chairs is given by the sum of the DLH used up for both products multiplied by the overhead rate:

A =(20+35)*\$100\\A=\$5,500

The total amount allocated to these products is $5,500.

Cassie is a half pound of sugar in her cabinet her cake recipe calls for two tenths of a pound of sugar how many cakes can she m
mamaluj [8]
The information's given in the question should be very minutely checked. Based on those given information's the answer to the question can easily be deduced.
Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
                                                                                                   = 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
                                                                        = 5/2
                                                                        = 2 1/2
So from the above deduction we can easily conclude that Cassie can make a total of 2 cakes with the sugar she has and there will still be some sugar left.

Which set of numbers best describes the possible values of x in the equation below?[x-1]=[x] all integer values of x all real nu
SCORPION-xisa [38]

[x] represents floor function also called as Greatest integer function.

Floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to.

like [1.5]=1

[0.7]=0

[-0.3]=-1

Now we have to find set of x-values which satisfies equation [x-1]=[x]

Due to -1 in [x-1], it always produces output value one less than value of [x]

for example when x=0.5 then [x]=[0.5]=0, [x-1]=[0.5-1]=[-0.5]=-1

when x=1.5 then [x]=[1.5]=1, [x-1]=[1.5-1]=[0.5]=0

when x=3 then [x]=[3]=3, [x-1]=[3-1]=[2]=2

From above results we can see that there is no value of x which satisfies the given equation [x-1]=[x]

Hence there is NO solution.

The lengths of the sides of a rectangle are consecutive prime numbers. The area of the rectangle is represented by a three-digit
PIT_PIT [208]

Answer:

Perimeter = 72

Step-by-step explanation:

<u>Mathematics Puzzle</u>

The area of a rectangle is the product of the base and the height

A=b.h

We know the base and the height are two consecutive prime numbers, not much of useful information so far.

We also know the area is composed only of the two smallest prime digits. Those digits are 2 and 3. If the number is reversed and it's not changed, then we only have two possible values for the area: 232 and 323.

We only need to find two consecutive prime numbers which product is one of the above. The number 232 has no prime factors: 232 = 8*29.

The number 323 is the product of 17 and 19, two consecutive prime numbers, thus the dimensions of the rectangle are 17 and 19.

The perimeter of that rectangle is 2*17+2*19= 72
