Parker has a part-time job at an ice skating rink selling hot cocoa. He decided to plot the number of hot cocoas he sold relative to the day's high temperature and then draw the line of best fit. Based on the line of best fit, how many hot cocoas would you predict Parker to sell if the day’s high temperature were 15

Answer:

best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!

Step-by-step explanation:

[tex]y = - 0.37 {x}^{2} + 6.15x + 52.3 \\ y = - 0.37 ({9}^{2} ) + 6.15(9) + 52.3 \\ y = - 0.37(81) + 6.15(9) + 52.3 \\ y = - 29.97 + 55.35 + 52.3 \\ y = 77.68[/tex]

The value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

It is defined as the combination of constants and variables with mathematical operators.

We have an epression:

= 6 +5. (8 + 2)²

We can solve the above expression by BODMAS:

= 6 + 5(10)²

= 6 + 5(100)

= 6 + 500

= 506

Thus, the value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

Answer:

Step-by-step explanation:

Remark

The position of these two angles is called vertically opposite. Every time two lines cross like this, you get vertically opposite angles. The point is that vertically opposite angles are equal.

x + 5= 46                Subtract 5 from both sides

x + 5-5 = 46-5

Answer:

y ≤ 66.28 -> -∞

Step-by-step explanation:

y = a (x-h)² + k     ... (h,k): vertex

y = - 32x² + 90x + 3

  = -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)

  = -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28)   ... 90/64=1.41

  = -32 (x - 1.41)² + 66.28

h = 1.41

k = 66.28 .... extremum of y value

y ≤ 66.28 (y is real number)

The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.

Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.

We have data shown in the table:

Total number of T-shirts = 200+300+400+300 = 1200

As there are only 400 T-shirts left it means,

So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.

200 T-shirts left in the June stock

Out of 300, there are 200 T-shirts left in the month of July.

Cost for 200 T-shirts = 200×8 = $1600

Cost for 200 T-shirts = 200×10 = $2000

Total cost = 1600+2000

= $3600

Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

Answer: 44 m

Step-by-step explanation:

Given

The area of the trapezium is [tex]A=480\ m^2[/tex]

Distance between parallel sides [tex]h=15\ m[/tex]

One of the parallel sides is [tex]20\ m[/tex]

Suppose the other parallel side is [tex]x[/tex]

The area of the trapezium is

[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]

Put values

[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]
