The spinner is equally likely to land on any of the six sections. a spinner contains 6 equal sections: 1, 2, 3, 4, 5, 6. section

tangare [24]

The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt

<h3>What is probability?</h3>

Probability is the likelihood or chance that an event will occur. Mathematically;

Probability = Expected/Total

If the spinner is spinned, the total outcome is 1/6

Pr(greater than 4) = 2/6 = 1/3

Pr(shaded section) = 3/6 = 1/2

Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section) = 5/6

Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths

28. sylvia researched changes in the deer population in her state's parks during her lifetime

kifflom [539]

Using an exponential function, it is found that it will take 24 years for the current population of 4800 deer to reduce to 600.

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change, as a decimal.

In this problem, considering the initial value of 4800, and that the population halves every 8 years, the equation is given by:

$A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}$

The population will be of 600 when A(t) = 600, hence:

$A(t) = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}$

$600 = 4800\left(\frac{1}{2}\right)^{\frac{t}{8}}$

$\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{600}{4800}$

$\left(\frac{1}{2}\right)^{\frac{t}{8}} = \frac{1}{8}$

$\left(\frac{1}{2}\right)^{\frac{t}{8}} = \left(\frac{1}{2}\right)^3$

Hence:

t/8 = 3.

t = 24.

It will take 24 years for the current population of 4800 deer to reduce to 600.

A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,

Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle so, it will follow the Pythagoras theorem:

$hypotenuse^2=side^2+side^2$ (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

$x^2=3^2+4^2$

$x^2=9+25$

$\Rightarrow x=5$

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.

use the leading coefficient and degree of the polynomial function f(x)=x^3-7x^2+10x to determine the end behaviour of its graph.

Masja [62]

Answer:

The domain is all real numbers and the range is all real numbers as-well.

As x approaches infinity, so does y.

As x approaches -infinity, so does y.
