1 answer:

7 0

Problem
What number represents a 300% increase of 25?

Result
75.

Solution
100% of 25 is 25, so 300% of 25 would be 75, because:
25 · 3 = 75

Classify the quadrilateral Then, find x and y.

jeka57 [31]

Answer:

Square

x = 2

y = 1

Step-by-step explanation:

All sides of the given quadrilateral are marked with identical signs so all sides are equal.
Also, each angle is right angle.
So it is a square.

Measures of all ll sides of a square are equal.

Therefore,

5x - 4 = 3x

5x - 3x = 4

2x = 4

x = 4/2

x = 2

5y + 1 = 2y + 4

5y - 2y = 4 - 1

3y = 3

y = 3/3

y = 1

<h3>What is geometric progression GP?</h3>

A sort of sequence known as geometric progression (GP) is one in which each following phrase is created by multiplying every preceding term by such a fixed number, or "common ratio."

The general form of GP is

a, ar, ar², ar³ ... arⁿ⁻¹

where, a is the initial term.

r is the common ratio.

According to the question,

The initial term is; a = 2.

The common ratio r = 2.

The threshold value beyond which person start feeling pain is 127.

Thus, last term; arⁿ⁻¹ = 128 (1 feet beyond 127 person start feeling pain)

Last second value is arⁿ⁻².

As, the common ratio is same in GP.

Thus, arⁿ⁻¹ / arⁿ⁻² = ar/a

==> 128/arⁿ⁻² = r

==> 128/arⁿ⁻² = 2

==> 2×2ⁿ⁻² = 64

==> 2ⁿ⁻² = 32

==> n = 7

As, i step is of 2 feet, the total steps taken by the person is 2×7 = 14.

Therefore, the total number of steps beyond which person will feel pain is 14.

The attendance at baseball games at a certain stadium is normally distributed, with a mean of 30,000 and a standard deviation of

lakkis [162]

Answer:

a) 0.964

b) 0.500

c) 0.885

d) $x \geq 32467.5$

e) 0.997

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 30000

Standard Deviation, σ = 1500

We are given that the distribution of attendance at stadium is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(attendance is greater than 27,300)

P(x > 27300)

$P( x > 27300) = P( z > \displaystyle\frac{27300 - 30000}{1500}) = P(z > -1.8)$

$= 1 - P(z \leq -1.8)$

Calculation the value from standard normal z table, we have,

$P(x > 27300) = 1 - 0.036 = 0.964 = 96.4\%$

b) P(attendance greater than or equal to 30000)

$P(x > 30000) = P(z > \displaystyle\frac{30000-30000}{1500}) = P(z \geq 0)\\\\P( z \geq 0) = 1 - P(z \leq 0)$

Calculating the value from the standard normal table we have,

$1 - 0.500 = 0.500 = 50\%$

c) P(attendance between 27000 and 32000)

$P(27000 \leq x \leq 32000) = P(\displaystyle\frac{27000 - 30000}{1500} \leq z \leq \displaystyle\frac{32000-30000}{1500}) = P(-2 \leq z \leq 1.33)\\\\= P(z \leq 1.33) - P(z < -2)\\= 0.908 - 0.023 = 0.885 = 88.5\%$
