95+(3x+23)+(7x-4)+(9x-6)+90 = (5-2) x 180
x = 18

9)
41+(3x+6)+(7x-11)+62+(4x+7)+(6x-5) = 360
x = 13

Select the correct symbol to make 22/7 √17 a true statement Options: <, >, or =

siniylev [52]

Among the given numbers, $\sqrt{17} > \frac{22}{7}$

We have two numbers, which are 22/7 and $\sqrt{17}$

Both of the numbers are irrational numbers, they are nonrepeating and nonterminating.

A fraction written in a particular way is called decimal form.

Now, evaluating both the given numbers in decimal form, we get,

22/7 = 3.14

and $\sqrt{17} = 4.12$

Now, Clearly, 4.12 > 3.14

Thus, $\sqrt{17} > \frac{22}{7}$

Solve the system by substitution. y = 3x + 14 y = X

lys-0071 [83]

Answer:

$\boxed{x = -7~~and~~ y =-7}$

Step-by-step explanation:

y = 3x + 14

y = x

x = 3x + 14

3x - x = -14

2x = -14

$x = \frac{-14}{2}$

x = -7

y = x

y = -7

When Mrs. JHixson gave a test, the scores were normally distributed with a mean of 78 and a standard deviation of 6. This means

Sergio039 [100]

For normal distribution 95% lie in the range mean-2*standard deviation for lower bound and mean+2*standard deviation for upper bound.

Upper bound is 78+2*6=78+12=90
Lower bound is 78-2*6=78-12=66

The world population was 2560 million people in 1950 and 3040 million in 1960 and can be modeled by the function p(t) 2560e0.017

almond37 [142]

Answer:

Step-by-step explanation:

The average rate of change is the slope. However, since this is not a linear function but an exponential one, we cannot determine the slope of the function, only the slope of the secant line that connects the x-values of 4 and 8. In order to do that we need to find the corresponding y-coordinate that goes with each of those x-values and plug them into the slope function. What we will get is a very loose interpretation of the rate of change of population, but that's all we have short of using calculus. It would be a closer estimation if we looked at x values of 4 and 5, or eve 4 ad 4.5. But that's not what we're being asked. So let's get to it.

Sub first 4 in for x and then 8, to get each y value:

$P(4)=2560e^{(.017185)(4)}$ to get that P(4) = 2742.16

$P(8)=2560e^{(.017185)(8)}$ to get that P(8) = 2937.29

The coordinates for these are (4, 2742.16) and (8, 2937.29)

Plug into the slope formula:

$m=\frac{2937.29-2742.16}{8-4}$ which gives you, in decimal form rounded to the nearest hundredth,

48.78 million.

The interpretation of this value in our situation is that between 1954 and 1958 the population increased 48.78 million people per year.
