Answer:

The dependent variable is h and the independent variable is t

Step-by-step explanation:

Given

h(t) = 4t + 5

Required

The dependent and the independent variable

The dependent variableis the variable whose value depends on another.

In the above equation, the height (h) depends on time (t) for its value

Hence,

The depe ndent variable is h and the indep endent variable is t

Jim drove 204 miles in 4 hours. If he can keep the same pace how long will it take him to drive 918 miles
SSSSS [86.1K]
18 hours.

Proportions and stuff.

\frac{204}{4} = \frac{918}{x}

Cross multiply,

204x = 918 * 4

204x = 3672
/204      /204
x = 18

18 hours.

Juliette [100K]

Answer:

12x^2+9x

Step-by-step explanation:

The formula of the area of a triangle is \frac{bh}{2}. Plugging in the given base and height values, you get \frac{(4x+3)(6x)}{2}=\frac{24x^2+18x}{2}=12x^2+9x. Hope this helps!

A survey finds that 55 people out of 170 favor increasing property taxes to help pay for a new library. If this data is used to
Aloiza [94]

Answer: B. 0.036

Step-by-step explanation:

Formula for standard error :

SE=\sqrt{\dfrac{p(1-p)}{n}}

, where p = Population proportion and n= sample size.

Let p be the population proportion of the people who favor new taxes.

As per given , we have

n= 170

p=\dfrac{55}{170}\approx0.324

Substitute these values in the formula, we get

SE=\sqrt{\dfrac{0.324(1-0.324)}{170}}\\\\=\sqrt{0.00129}\\\\=0.0359165699921\approx0.036

Hence, the standard error of the estimate is 0.036.

∴ The correct answer is OPTION B. 0.036
