Answer:

(-4/3), 0.4, 0.8, √2, √11

Step-by-step explanation:

√11=3.316624790355399849114932736670686683927088545589353597058

0.4

(-4/3) = -1.33333333333333333333333333333333333333333333333333333333

0.8

√2=1.414213562373095048801688724209698078569671875376948073176

Thus :

(-4/3)

0.4

0.8

√2

Circle P has a radius of 14 feet. Circle Q has a diameter of 14 feet. What is the ratio of the circumference of P to the circumf

Salsk061 [2.6K]

Answer:

2:1

Step-by-step explanation:

Circle P has radius 14 feet.

The circumference of this circle is given by:

$C=2 \pi \: r$

We plug in the radius to get:

$C=2\pi \: \times 14 = 28\pi$

Circle Q has diameter 14 feet.

The circumference of this circle is given by

$C=\pi \: d$

We substitute the diameter d=14 to get,

$C=\pi \: \times 14$

$C=14\pi$

The ratio of the circumference of P to the circumference of Q is

$28 \pi: 14\pi = 2:1$

A person x inches tall has a pulse rate of y beats per minute, as given approximately by yequals600 x Superscript negative 1 di

tankabanditka [31]

Answer:

a) 5.13beats/min

b) 2.82 beats/min

Step-by-step explanation:

Given the pulse rate of a person modelled by the equation y = 600x^-1/3 for 30≤x≤75

If the height is 39inches, the instantaneous rate of change of pulse rate for the heights will be expressed as;

y = 600(39)^-1/3

y = {600(1/39)}/3

y = 600/39×3

y = 600/117

y ≈ 5.13beats/min

The instantaneous rate for a 39 inches tall person is 5.13 beats per min

b) For a 71inches tall person, the beat rate will be expressed as;

y = 600(71)^-1/3

y = {600(1/71)}/3

y = 600/71×3

y = 600/213

y ≈ 2.82 beats per minute

The instantaneous rate for a 71 inches tall person is 2.82 beats per min

Use the Central Limit Theorem to find a mean given a probability Question A video game company sells an average of 132 games a m

aev [14]

Answer:

The number of games must a store sell in order to be eligible for a reward is 135.

Step-by-step explanation:

Let the random variable X represent the number of video games sold in a month by the sores.

The random variable X has a mean of, μ = 132 and a standard deviation of, σ = 9.

It is provided that the company is looking to reward stores that are selling in the top 7%.

That is, $P (\bar X > \bar x) = 0.07$ .

The z-score related to this probability is, z = 1.48.

Compute the number of games must a store sell in order to be eligible for a reward as follows:

$z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}$

$\bar x=\mu+z\cdot \sigma/\sqrt{n}$

$=132+1.48\times (9/\sqrt{36})\\\\=132+2.22\\\\=134.22\\\\\approx 135$

Thus, the number of games must a store sell in order to be eligible for a reward is 135.
