Answer:

C) $5(2)(6.25)+2.5t$ ≥ 85

Step-by-step explanation:

$5(2)(6.25)+2.5t$ ≥ 85

Jessamine wants to ride her bike at least 85 miles per week.

t must make the whole equation AT LEAST 85 miles. So t MUST be larger than or equal to 85.

Answer:

Step-by-step explanation:

If I'm not mistaken, she wants to ride atleast 85 miles per week. If you add up all of the values from going to and from the school, you would get 62.5 miles. So for it to add up to 85 miles, she would have to atleast do 9 trips around the park.

These numbers I believe do not matter however, all you need to do is put in C for greater than or equal to 85.

Write an equation in slope-intercept form: (1,6) and (2,3) are on the line

s344n2d4d5 [400]

Step-by-step explanation:

eqn of line : y = mx+ c

m = slope or gradient

c = y-intercept.

Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

$m \: = \frac{y1 - y2}{x1 - x2} \\ = \frac{6 - 3}{1 - 2} \\ = \frac{3}{ - 1} \\ = - 3$

Substitute x = 1 and y = 6 into equation,

$6 = ( - 3)(1) + c \\ 6 = - 3 + c \\ c = 6 + 3 \\ = 9$

Therefore substituting m and c value, equation of line is

$y = - 3x + 9$

Answer:

E (Y) = 3

Step-by-step explanation:

If a 4-sided die is being rolled repeatedly; and the odd-numbered rolls (1st 3rd,5th, etc.)

The probability of odd number roll will be, p(T) = $\frac{1}{2}$

However, on your even-numbered rolls, you are victorious if you get a 3 or 4. Also, the probability of even number roll, p(U) = $\frac{1}{2}$

In order to calculate: E (Y); We can say Y to be the number of times you roll.

We know that;

E (Y) = E ( Y|T ) p(T) + E ( Y|U ) p(U)

Let us calculate E ( Y|T ) and E ( Y|U )

Y|T ≅ geometric = $\frac{1}{4}$

Y|U ≅ geometric = $\frac{1}{2}$

also; x ≅ geometric (p)

∴ E (x) = $\frac{1}{p}$

⇒ $\frac{Y}{T}$ = 4 ; also $\frac{Y}{U}$ = 2

E (Y) = 4 × $\frac{1}{2}$ + 2 ×

= 2+1

E (Y) = 3

Answer:

circle question: 69.66

the other question: 66.8

Step-by-step explanation:

For the circle question:

the circle is inscribed in the square, so the diameter of the circle = side of the square

so we need to find the area of square and circle

then do this

square area - circle area

square area(side×side) = 324

circle area(pi×r^2)≈254.469

so shaded region = 69.66

__________

the other question:

we need to find the area of triangle and the area of the rectangle and add them together

A of Triangle (1/2×base×hight) = 34.32

A of rectangle (width × length) = 31.92

add them, so the answer will be = 66.8
