Step-by-step explanation:
For the parabola( top question)
- X intercepts are (2,0) (4,0)
- Y intercepts are (0,4)
- Intervals of Increasing are [3, ♾)
- Intervals of decreasing are (- ♾, 3]
- The domain is All Real Numbers or (-♾, ♾)
- The range is [1, ♾)
- There is no maximum value of this function
- The minimum value is -1
- The axis of symmetry is x=3
- f(6)=4
For the absolute value equation, bottom question
- X intercepts is (2,0)
- Y intercepts are (0,3)
- The Intervals of Increasing are [2,infinity)
- The Intervals of decreasing are ( negative infinity,2]
- The domain is All Real Numbers or (negative ♾, positive ♾)
- Range is [0, positive ♾)
- There is no maximum value of the function
- The minimum value is 0
- f(-1)=4.5
We see that the angle measures are the same, but the side lengths aren't, so these shapes qualify as similar. Since it's similar, they are also the same shape.
Choices C and D
:)
A standard deck of 52 cards has 13 ranks (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King) and 4 suits ($\spadesuit$, $\heart
Furkat [3]
Answer:
4 / 663
Step-by-step explanation:
Given that :
Number of cards in a standard deck = 52
Number of 3's in s standard deck = 4 (each suit has one card each)
Number of 8's in a standard deck = 4 (each suit has one card each)
Probability, P = required outcome / Total possible outcomes
Choosing without replacement :
P(top card is a 3) = 4 / 52
P(second draw is 8) = 4 / 51
P(top card is a 3 and second is 8) :.
4/52 * 4/51 = 16 / 2652 = 4 / 663
Answer:
D) 10
Step-by-step explanation:
The slope of the line y=10x+3 is 10 because in the slope form y=mxtb m represents the slope. In this case 10 is m, therefore the slope is 10. This mean the slope rises 10 units and runs 1 unit since slope is also known as rise/run.
Answer: The margin of error =
Step-by-step explanation:
Given
Sample size (n) = 1000
Population proportion = 0.4
= 1 - confidence level
= 1 - 0.95
= 0.05
= 0.03
The margin of error change to to
