Answer:

The number of different possible values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

Step-by-step explanation:

Given : For an integer n, the inequality $x^2 + nx + 15 < 0$ has no real solutions in x.

To find : The number of different possible values of n ?

Solution :

The given inequality is $x^2 + nx + 15 < 0$ have no solution then the discriminant must be less than zero.

i.e. $b^2-4ac$

Here, a=1, b=n and c=15

${n}^{2} - 4 \times 1 \times 15 \: < \: 0$

${n}^{2} - 60 \: < \: 0$

$n^2$

$n$

i.e. $- 7.75 \: < \: n \: < \: 7.75$

The integer values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

these polygons are similar. find the similar ratio. any help ? please? ( also how do I ask a question ok here without typing 20

Answer: Choice B) 3/5

==================================================

Explanation:

The smaller horizontal side is JM = 15
The larger horizontal side is NQ = 25

The ratio of these corresponding sides is:
small/large = 15/25 = (5*3)/(5*5) = 3/5

----------------

Alternatively,

The smaller vertical side is ML = 18
The larger vertical side is QP = 30

The ratio of these corresponding sides is:
small/large = 18/30 = (6*3)/(6*5) = 3/5

----------------

Either way, the answer is 3/5

This probability distribution shows

Charra [1.4K]

Answer:

The probability that a student earns a grade of A is 1/7.

Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:

P(E) = n(E) / n(S)

As the total number of students = n(S) = 35

Students getting the grade A = n(E) = 5

So, the probability that a student earns a grade of A:

P(E) = n(E) / n(S)

= 5/35

= 1/7

Hence, the probability that a student earns a grade of A is 1/7.
