Answers
Answer:
-3u-4v
Step-by-step explanation:
5u+6v-(8u+10v)
=5u+6v+-1(8u+10v)
=5u+6v+-1(8u)+-1(10v)
=5u+6v+-8u+-10v
(combine like terms)

The value of the subtraction will be equal to -3u-4v.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two expressions are (5u + 6v) and (8u + 10v). The subtraction will be calculated as,
5u+6v-(8u+10v)
S =5u+6v+-1(8u+10v)
S =5u+6v+-1(8u)+-1(10v)
S =5u+6v+-8u+-10v
(combine like terms)
S =5u+6v+-8u+-10v
S =(5u+-8u)+(6v+-10v)
S =-3u-4v
Therefore, the value of the subtraction will be equal to -3u-4v.

Answer:
89 degrees
Step-by-step explanation:
Since these angles make up a triangle, we know that the total of these angles will make 180 degrees. So, we need to set the equations up appropriately, and solve for x:
[tex]180=(4x+1)+(2x-6)+(6x-7)\\180=12x-12\\192=12x\\x=16\\[/tex]
Then, you plug 16 back into the equation for angle J, and simplify:
[tex](6(16)-7)\\(96-7)\\(89)[/tex]
Therefore, the answer is 89 degrees.

LA = [ ? ]7 cm2
Answers
The lateral surface area of the cone will be 65π square cm.
What is the lateral surface area of a cone?Let d be the diameter of the base circle, l be the slant height, and h be the height of the cone.
Then the lateral surface area of the cone will be
LSA = πrl
Then the slant height is given as
l² = r² + h²
l² = 5² + 12²
l² = 25 + 144
l² = 169
l = 13 cm
Then the lateral surface area will be
LSA = π × 5 × 13
LSA = 65π cm²

Answers
Answer: 6 possible outcomes
Step-by-step explanation:

white shirt - black pants
6 outcomes
The total number of outcomes is given by the equation A = 6 outcomes
What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the number of outcomes be represented as set A
Now , the shirts be represented as set 1
The value of set 1 = { blue shirt , black shirt , white shirt }
The number of elements in set 1 = 3
The pair of pants be represented as set 2
The value of set 2 = { blue pair , black pair }
The number of elements in set 2 = 2
Now , the total number of possible outcomes A = number of elements in set 1 x number of elements in set 2
Substituting the values in the equation , we get
The total number of possible outcomes A = 3 x 2
The total number of possible outcomes A = 6 outcomes
Therefore , the value of A is 6 outcomes
Hence , the number of outcomes is 6

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval
Answers
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.
Camden needs to lease out a music studio to record his new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The studio charges $50 per hour of use and the total cost charged for 5 hours is $700. Write an equation for the function P ( t ) , P(t), representing the amount of money Camden would have to pay to use the studio for t t hours.
Answers
Answer: [tex]P(t)=450+50t[/tex]
Step-by-step explanation:
Given
Studio charge $50 per hour and fixed charge for initial use
For 5 hours, it charges $700
Suppose x is the fixed charge
[tex]\therefore 700=x+50\times 5\\\Rightarrow x=700-250\\\Rightarrow x=\$450[/tex]
For t hours, studio charges
[tex]\Rightarrow P(t)=450+50t[/tex]
