Answer:

d) $b = \sqrt{105}$ ≈ 10.24

Step-by-step explanation:

$a^2+b^2=c^2$

$(4)^2+b^2=(11)^2$

$16+b^2=121$

subtract 16 from both sides

$b^2=105$

$b=\sqrt{105$

b = 10.24695...

b ≈ 10.24

A student placement center has requests from five students for interviews regarding employment with a particular consulting firm

bagirrra123 [75]

Answer: a) 1 / 10

b) 3 / 10

c) 1 / 5

d) 3 / 5

Step-by-step explanation:

Total number of requests five students for interviews regarding employment with the consulting firm = 5

Number of students that are maths majors = 3

Probability of selecting a maths student is 3 / 5

Number of students that are statistics majors = 2

Probability of selecting a statistics student is 2 / 5

a) the probability that both selected students are statistics majors

= 2 / 5 × 1 / 4 = 2 / 20 = 1 / 10

b) the probability that both students are math majors

= 3 / 5 × 2 / 4 = 6 / 20 = 3 / 10

c) the probability that at least one of the students selected is a statistics major will be p( one statistics and the other, maths) + p( one maths and the other, statistic) - p( both are mathematics)

= (2 / 5 × 1 / 4 ) + ( 2 / 5 × 3 / 4 ) - (3 / 5 × 2 / 4)

= 2 / 10 + 6 / 20 - 6 / 20

= 1 / 5 + 3 / 10 - 3 / 10

= 1 / 5

d) the probability that the selected students have different majors is p(one is maths and the other is statistics) + p(one is statistics and the other is maths)

(3 / 5 × 2 / 4) + (2 /5 × 3 / 4)

= 6 / 20 + 6 / 20 = 12 / 20

= 3 / 5

The sum of four consecutive numbers equals b+6. What are the numbers?

jarptica [38.1K]

let the first number be b

therefore the second,third and fourth numbers are b+1,b+2 and b+3

b+b+1+b+2+b+3=b+6

4b+6=b+6

4b-b=6-6

A function is shown f=(x)=x^2+ 2X-3

Brut [27]

Answer:

x intercepts at (-3,0), and (1,0)

there is a minimum at (-1,-4)

Step-by-step explanation:

Please see attached image for the requested graph of the function $f(x) = x^2+2x-3$ , and observe that the crossings of the x-axis are at the points (-3,0), and (1,0) , marked in red in the image.

We can also see that there is no maximum, but a minimum value, and located at the point (-1,-4) [marked in green in the image]
