Answer:
Dot plot
Step-by-step explanation:
In a dot plot, the temperature of a day is represented by 1 dot. There are 30 dots on the box plot shown in the attachment that was made by Tia.
This dot plot display makes it easier to find how many days had a temperature that is higher than 15°.
Thus, from the dot plot, we have:
2 dots representing 2 days having a temperature of 16°C each
2 days also have daily temperature of 17°C
2 days have temperature of 18°C as well, and
1 day has temperature of 19° C.
Therefore, the number of days that had a temperature above 15°C is 7 days.
Answer:
f(- 1) = 3
Step-by-step explanation:
To evaluate f(- 1) substitute x = - 1 into f(x) , that is
f(- 1) = (- 1)² - 5(- 1) - 3 = 1 + 5 - 3 = 3
Answer:
352.
y = 8c + 16d
Step-by-step explanation:
Expression:
c = cats
d = dogs
Expresion: y = 8c + 16d
Now use it by plugging in.
y = 8c + 16d
y = 8(16) + 16(14)
y = 128 + 224
y = 352 (that's how much he earned)
-0.8* 10.8x= -8.64x
-0.8* -20= 16
-0.8* 3.2x =-2.56x
so it is equivalent to the expression -8.64x+16-2.56x but add like terms so it becomes -8.64x-2.56x+16. The final answer is -11.2x=16
