Answer:

100 numbers

Step-by-step explanation:

There are 100 numbers with 5 as the hundreds digit. (500-599)

There are 100 numbers with 6 as the hundreds digit. (600-699)

There are 50 even numbers with 5 as the hundreds digit.

(500, 502, 504, ... , 598)

There are 50 even numbers with 6 as the hundreds digit.

(600, 602, 604, ... , 698)

50+50=100 numbers

A random two -digit number (10-99)is drawn find each probability
son4ous [18]

Answer:

Step-by-step explanation:

Given that two digit numbers are used and one digit is drawn randomly.

Sample space = {10,11,...99}

n(S) = 90

32 is only one number favourable

Hence P(32) = 1/90

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

Odd numbers are exactly 45.

Hence prob (odd number) = 45/90 = 1/2

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

Multiples of 5 are 10,15,.....95

There are exactly 18 numbers.

Hence P(a multiple of 5) = 18/90 =1/5

Answer: hope this helps love.

Step-by-step explanation:

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

My quadrilateral has no lines of symmetry but it does have rotation symmetry. what is it?”
Elina [12.6K]

We have to identify the quadrilateral with no line of symmetry and have rotational symmetry.

Line of symmetry  is the imaginary line which divide the given quadrilateral in two equal halves.

Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Parallelogram is a quadrilateral which has no line of symmetry as we can not draw any imaginary line which divides the parallelogram in two equal halves.

But Parallelogram has rotational symmetry as when a parallelogram is rotated around a center point (turned) a number of degrees and parallelogram appear the same.

Hence, Parallelogram is the quadrilateral.
