a(1) = -4(1)-3 = -4-3 = -7

a(2) = -4(2)-3 = -8-3 = -11

a(3) = -4(3)-3 = -12-3 = -15

a(4) = -4(4)-3 = -16-3 = -19

a(5) = -4(5)-3 = -20-3 = -23

So, sequence would be -7,-11,-15,-19,-23

Answer:

a. discrete random variable

Step-by-step explanation:

A discrete random variable is one which may take on only a countable number of distinct values such as 0, 1, 2, 3, 4, etc. Discrete random variables are usually countable.

From the question:

The experiment consist of making 80 telephone calls in order to sell a particular insurance policy. 80 here is the random variable; 80 is countable anf finite.

So, 80 is a discrete random variable

Which three lengths could be the lengths

Fed [463]

Given:

The three lengths in the options.

To find:

Which three lengths could be the lengths of the sides of a triangle?

Solution:

If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.

In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.

Sum of two smaller sides is:

$4+8=12$

$4+8$

So, the triangle is not possible.

In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.

Sum of two smaller sides is:

$13+11=24$

$13+11>23$

So, the triangle is possible.

In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.

Sum of two smaller sides is:

$5+12=17$

$5+12$

So, the triangle is not possible.

In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.

Sum of two smaller sides is:

$8+16=24$

$8+16$

So, the triangle is not possible.

Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

GIVE OUT BRAINLY 2) Kathleen is a sales associate in a jewelry store. She earns $560/wk plus an 8% commission on sales. How much

pashok25 [27]

Answer:

1750

Step-by-step explanation:

Earns per week: $560

Total sales per week: $x$

Weekly commission on sales: 0.08 $x$

Total Earning per week: $560 + 0.08x$

$560 + 0.08x \geqslant 700$

Simplifying this inequality:

$560 + 0.08x \geqslant 700\\0.08x \geqslant 700 - 560\\0.08x \geqslant 140\\\\x \geqslant \frac{140}{0.08}\\\\x \geqslant 1750$

Her sales must be at least $1750.
