Answer:

$1\dfrac{17}{19}$

Step-by-step explanation:

19 bananas =1 watermelon

3 pineapples =1 watermelon

Then

19 bananas = 3 pineapples

1 pineapple = 3 grapes,

then

3 pineapples = 9 grapes

3 pineapples = 9 grapes

19 bananas = 3 pineapples

then

9 grapes = 19 bananas

9 grapes = 19 bananas

x grapes = 4 bananas

Write a proportion:

$\dfrac{9}{x}=\dfrac{19}{4}$

Cross multiply

$19x=9\cdot 4\\ \\19x=36\\ \\x=\dfrac{36}{19}=1\dfrac{17}{19}$

Help!!!! And is the first on correct

ExtremeBDS [4]

2s+5≥49

First: Subtract 5 on both sides
You'll get: 2s ≥ 44
Last: Divide each side by 2 so your s would be alone
You'll get: s ≥ 22 <That would be your answer

HOPE THIS HELPS! ^_^

Suppose there are three balls in a box. On one of the balls is the number 1, on another is the number 2, and on the third is the

quester [9]

Step-by-step explanation:

a) X is a discrete uniform distribution. As the number of outcomes is only 3.

b) sum is at least 4

X ≥ 4

i.e (1,3) or (2,3)

probability of X ≥ 4 is 2/3

2/3= 0.667

66.7 % is the probability of the outcome to have a sum at least 4.

c) The 3 likely outcome of X

(1,2) where X ; 1+2=3

(1,3) where X ; 1+3=4

(2,3) where X ; 2+3=5

Mean = 3+4+5/ 3

Mean = 4

Answer:

The line does not intersect the curve

Step-by-step explanation:

Assuming that we are looking for the points of intersection of

${x}^{2} + {y}^{2} = 25$

and

$2x + y = 25$

We make y the subject in the second equation to get:

$y = 25 - 2x$

When we substitute into the first equation:

${x}^{2} + {(25 -2 x)}^{2} = 25$

Let us expand to get:

${x}^{2} + 625 - 100x + 4 {x}^{2} = 25$

We obtain the standard form

$5 {x}^{2} - 100x + 600 = 0$

Divide through by 5

${x}^{2} - 20x + 120 = 0$

The discriminant is

${( - 20)}^{2} - 4 \times 1 \times 120 = - 80$

Hence the quadratic equation has no real roots.

This means the line and point has no point of intersection.
