5 0

Answer:

f(3)=11

Step-by-step explanation:

f(x) = 2x + 5

to find f(3) we simply plug in 3 where ever x is

So f(3) = 2(3) + 5

==> multiply 2 and 3

f(3) = 6 + 5

==> add 6 and 6

f(3) = 11

how do you write a linear equation when given a graph or table? and how do you analyze key features of a function when given its
Agata [3.3K]
When given a graph or table, you first want to figure out the slope. Look at the graph or table, and see how much does y change when x change in a certain amount? You want it as a rise/run so if x increases 2 when y increases 3 then the slope would be 3/2.

Next, you want to find the y intercept.
Look at the y value when x is 0. If the y is -2 when x=0, then b=-2.

When given its graph, find a y value when x is 0. If the y is 4 when x=0 then b=4

Identify two additional values for x and y in a direct variation relationship where y =11 when x=18
Ann [662]
In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.

So, you can find multiple values that meet this:

y = kx => k = y / x = 11 / 18

=> y = (11/18)x

Now you can give any value to x and fint the value of x that satisfy the relationship:

x           y = (11/18)x

1           11/18

2           11/18 * 2 = 11/9

18          11/18 * 18 = 11

36           11/18 * 36 = 22

So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x

Ivan

Answer:

Test statistic = 2.8965

Step-by-step explanation:

The test statistic is given by the formula

z = (x - μ)/σₓ

μ = mean = 0.799

x = proportion of literate people in Tamil Nadu = (983/1185) = 0.8295

σₓ = standard error of this calculated proportion = √[p(1-p)/n]

= √(0.8295 × 0.1705/1185) = 0.01093

z = (x - μ)/σₓ

z = (0.8295 - 0.799)/0.01093 = 2.8965

z = 2.8965

Hope this Helps!!!
