Evaluate bd/a+c if a=−2 , b=3 , c=−12 , and d=−4
Answer:
6/7
Step-by-step explanation:
First you just have to plug the numbers in so you get 3*-4/-2+(-12) which simplifies to -12/-14 which can be simplified to 6/7
The value of expression bd/a+c will be 6/7.
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The expression is ,
bd / a+c
And, The values are a=−2 , b=3 , c=−12 , and d=−4.
Now, Find the value of the expression we can substitute all the given values in the expression;
⇒ bd / a+c
⇒ 3 × (-4) / -2+(-12)
⇒ -12/-2-12
⇒ -12/-14
⇒ 12/14
⇒ 6/7
Thus, The value of expression bd/a+c will be 6/7.

Square both sides:
F^2 (2pi)^2 = g/l

Suppose approximately 75% of all marketing personnel are extroverts, whereas about 55% of all computer programmers are introverts. (For each answer, enter a number. Round your answers to the three decimal places.)
A. At the meeting of 15 marketing personnel, what is the probability that 10 or more are extroverts?
What is the probability that 5 or more are extroverts?
What is the probability that all are extroverts?
B. In a group of 5 computer programmers, what is the probability that none are introverts?
What is the probability that 3 or more are introverts?
What is the probability that all are introverts?
Answer:
A.)
0.852 ; 0.999 ; 0.013
B.)
0.018 ; 0.593 ; 0.050
Step-by-step explanation:
Given :
Proportion of marketing personnel that are extrovert, p = 0.75
1 - p = 1 - 0.75 = 0.25
Proportion of computer programmers that are introverts, p = 0.55
1 - p = 1 - 0.55 = 0.45
According to binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
A.) n = 15
Probability that 10 or more are extrovert
P(x ≥ 10) = p(x = 10) + p(x = 11) +... p(x = 15)
To save computation time, we can use a binomial probability calculator ;
P(x ≥ 10) = 0.8516 = 0.852
Probability that 5 or more are extrovert :
P(x ≥ 5) = p(x = 5) + p(x = 6) +... p(x = 15)
To save computation time, we can use a binomial probability calculator ;
P(x ≥ 5) = 0.9999 = 0.999
Probability that all are extrovert :
P(x = 15) = 15C15 * 0.75^15 * 0.25^0
P(x = 15) = 1 * 0.75^15 * 0.25^0
P(x = 15) = 0.01336 = 0.013
B.
What is the probability that all are introverts?
n = 5
None are introvert :
P(x = 0) = 5C0 * 0.55^0 * 0.45^5
P(x = 0) = 1 * 1 * 0.0184528125
P(x = 0) = 0.01845 = 0.018
P(x ≥ 3) = p(3) + p(4) + p(5)
To save computation time, we can use a binomial probability calculator ;
P(x ≥ 3) = 0.5931 = 0.593
Probability that all are introvert
P(x = 5) = 5C5 * 0.55^5 * 0.45^0
P(x = 5) = 1 * 0.55^5 * 0.45^0
P(x = 5) = 0.0503 = 0.050

write. (0.25)³ as a multiplication
A number raised to an exponent is the number multiplied by itself the number of times the exponent is.
The exponent is 3, so this means 0.25 is multiplied by itself 3 times.
0.25^3 = 0.25 x 0.25 x 0.25
Answer:0.100
Step-by-step explanation:
If you sed the rule of counting decimal places in the equation to find the number of decimal places in the answer you must not discard zeros too early. For example to multiply 0.25 by 0.4 you need 2+1 decimal places and the multiplication without a decimal point gives 0100. The answer is therefore 0.100.

What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Bowl A contains three red and two white chips, and bowl B contains four red and three white chips. A chip is drawn at random from bowl A and transferred to bowl B.
The probability will be calculated as:-
[tex]\rm P_B(r)=P_A(r)P_B(r)+P_A(w)P_B(r)\\\\P_B(r) = (\dfrac{3}{5})(\dfrac{5}{8})+(\dfrac{2}{5}(\dfrac{4}{8})\\\\P_B(r)=\dfrac{23}{40}[/tex]

Answer:
$27.14
Step-by-step explanation:
Price of 1 DVD: $9.10
Price of 4 DVDs: 4 * $9.10 = $36.40
Discount: 25%
Now we find 25% of $36.40.
25% of $36.40 =
= 0.25 * $36.40
= $9.10
The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.
$36.40 - $9.10 = $27.30
Now we need to apply the 6.75% tax to $27.30.
6.75% of $27.30 =
= 0.0675 * $27.30
= $1.84
The sales tax is $1.84.
Now we add the sales tax amount to the total discounted price.
$27.30 + $1.84 = $29.14

What is the range of y = -5sin(x)?

Answer:
[-5, 5] the Y value has a minimum of -5 and max of 5 so that is what your range is!
Step-by-step explanation:
[tex]\boxed{\boxed{\pink{\bf \leadsto The \ range \ of \ y \ is \ y \ \in \ [-5,5] .}}}[/tex]
Step-by-step explanation:A function is given to us and we need to find its range. So the given function is ,
[tex]\bf\implies y = -5\:sin(x) [/tex]
The lower bound of the range for sine is found by substituting the negative magnitude of the coefficient into the equation.
[tex]\bf \implies y = (-5) [/tex]
The upper bound of the range for sine is found by substituting the positive magnitude of the coefficient into the equation.
[tex]\bf \implies y = (5) [/tex]
Hence the range is ,
[tex]\boxed{\red{\bf -5 \leq y \leq 5 }}[/tex]
Interval Notation :-
[tex]\boxed{\red{\bf y \in [-5,5] }}[/tex]
Set builder Notation :-

[tex](a)[/tex] Find the relative growth rate.
[tex]P=Ae^{rt}[/tex] where given [tex]A=71, P(t)=120\;\;and \;\; t=\frac{1}{3}[/tex]

[tex]\Rightarrow \frac{120}{71} =e^{\frac{r}{3} }[/tex]
[tex]\Rightarrow 1.69=e^{\frac{r}{3} }[/tex]
[tex]\Rightarrow \ln1.69=\frac{r}{3}[/tex]
[tex]\Rightarrow 3\ln1.69=r \;\;\; or \;\;\; r=1.57[/tex]

Answer:
No
Step-by-step explanation:
SD=8+2+5+4+11+9÷6
13=10+9+20÷6
13=19+20÷6
13=39÷6
13=6.5-False=No
13 is not a usual number. A further solution of the given query is provided below.
Given:
Number of observations = 6
Series 8, 2, 5, 4, 11, 9
The Mean will be:
= [tex]\frac{Sum \ of \ observation}{Total \ number \ of \ observations}[/tex]
By substituting the values, we get
= [tex]\frac{8+2+5+4+11+9}{6}[/tex]
= [tex]\frac{32}{6}[/tex]
= [tex]6.5[/tex]
Now,
The Standard deviation will be:

= [tex]\sqrt{\frac{(1.5)^2+(4.5)^2+(1.5)^2+(2.5)^2+(4.5)^2+(2.5)^2}{6} }[/tex]

13 is not within the range of standard deviation. Thus it is not a usual number.

3x + y = -3
y = x + 5
Substitution pls show solving
Answer:
( -2, 3 )
Step-by-step explanation:
3x + y = -3
y = x + 5
Since "y" has been given to us, all we need to do is substitute.
3x + x + 5 = -3
Combine like terms
4x + 5 = -3
Subtract 5 onto both sides
4x + 5 - 5 = -3 - 5
4x = -8
Divide by 4 into both sides to isolate the variable
4x/4 = -8/4
x = -2
Now that we have x ( -2 ), we can substitute that to get what y is.
y = x + 5
y = -2 + 5
y = 3
( x, y ) ---> ( -2, 3 )
