The functions have complex roots from the image are

Functions (b) and (d). This is further explained below.

<h3>What is Function?</h3>

Generally, Function is simply defined as a connection between two or more variables that may be expressed mathematically.

In conclusion, Functions with graphs that never touch or cross the x-axis are said to have complicated roots, not real ones.

X + (x + 10) = 154
2 x + 10 = 154
2 x = 154-10 = 144
x = 72 (ans)
Not sure if it’s right

A cell phone store sells the basic model of a phone for $30 and the upgraded model for $100 when a customer signs a two-year agr

mixer [17]

<span>You need to set up 2 equations for this, a system to be exact let x represent the cheaper phone and y represent the upgraded phone for store costs you will have 5x+25y=200 for selling prices you will have 30x+100y=900 set these two equations together 5x+25y=200 30x+100y=900 multiply the first one by -4 and add them -20x-100y=-800 30x+100y=900 10x=100 x=10 10 cheaper phones, plug into any equation again 5(10)+25(y)=200 y=6<<<6 upgraded phones</span>

Suppose you have the following information. 12% of all drivers do not have a valid driver’s license, 6% of all drivers have no i

lubasha [3.4K]

Answer:

e) 0.14

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a driver does not have a valid driver's license.

B is the probability that a driver does not have insurance.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a driver does not have a valid driver's license but has insurance and $A \cap B$ is the probability that a driver does not have any of these things.

By the same logic, we have that:

$B = b + (A \cap B)$

We start finding these values from the intersection.

4% have neither

This means that $(A \cap B) = 0.04$

6% of all drivers have no insurance

This means that $B = 0.06$ . So

$B = b + (A \cap B)$

$0.06 = b + 0.04$

$b = 0.02$

12% of all drivers do not have a valid driver’s license

This means that $A = 0.12$

$A = a + (A \cap B)$

$0.12 = a + 0.04$

$a = 0.08$

The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

$P = a + b + (A \cap B) = 0.08 + 0.02 + 0.04 = 0.14$

So the correct answer is:

e) 0.14

Which of the following is the estimated amount of salt that will dissolve at 47 degrees?

Nina [5.8K]

Ths solubility curve can be used to obtain the amount of salt dissolved (solubility).

<h3>What is the solubility curve?</h3>

The solubility curve is a plot of the solubility of a substance against the temperature. It serves the purpose of being used to show the solubility of a susbtance at different temperatures. This question is incomplete hence we can not be able to deduce the solubility of the salt at this temperature.

If the solubility curve has been ploted, then we can be able to estimate the solubility of the salt from the graph.
