Answer:

Step-by-step explanation:

Given that Amélie runs a bakery. She wants to find out whether her cake sales are affected by the weather conditions. She recorded the daily temperature and the number of cakes she sold on different days of the year

Let us find the correlation coefficient for the variables x, daily temperature and y, no of cakes sold.

x y

 

42 39

45 52

48 31

54 61

59 72

62 35

64 61

65 34

67 58

75 45

84 24

 

r -0.197481837

Since r is nearer to 0 than to 1, we find that there is a negative very moderate correlation between the two variables.

We cannot conclude that  Amélie's cake sales are affected by the daily temperature.

X2 – 1x – 90 = 0 has solutions {a, b}. What is a + b?
s344n2d4d5 [400]

Answer:

a + b =1

Step-by-step explanation:

Write the given quadratic as x^2 – 1x – 90 = 0.  This factors into

(x - 10)(x + 9) = 0, and so the roots/solutions are {-9, 10}.

If we call -9 "a" and 10 "b," then the sum a + b is -9 + 10, or a + b =1.

A standard deck of cards contains 52 cards. One card is selected from the deck.
Anastaziya [24]

Answer:

1) Probability of randomly selecting a diamond or club = \frac{1}{2}

2)Probability of randomly selecting a diamond or club or heart = \frac{3}{4}

3) P(selecting a five or club) = \frac{4}{13}

Step-by-step explanation:

Total cards in the deck = 52

Noe Let E : favorable Event

So, P(E) =  \frac{\textrm{Number of Favorable outcomes}}{\textrm{Total outcomes}}

1 ) Probability of randomly selecting a diamond or club

Here the favorable event is picking a club or diamond

hence, favorable outcomes  = Number of club and diamond

= 13 + 13 = 26

⇒P(selecting a diamond or club) = \frac{26}{52}  = \frac{1}{2}

2) Probability of randomly selecting a diamond or club or heart

Here the favorable event is picking a diamond and club and heart.

hence, favorable outcomes = Number of   clubs + diamond + heart

= 13 + 13 + 13 = 39

⇒P(selecting a diamond or club or heart) = \frac{39}{52}  = \frac{3}{4}

3 )Probability of randomly selecting a five or club.

Here the favorable event is selecting a five or club.

hence, favorable outcomes = Number of 5 in a deck  + Number of clubs

=  3 +  13  = 16

⇒P(selecting a five or club) = \frac{16}{52}  = \frac{4}{13}
