Step-by-step explanation:

c^2 = a^2 + b^2

$\sqrt{40 ^{2} + 30 {}^{2} } = 50$

$\sqrt{60 {}^{2} - 40 {}^{2} } = 44.7$

Y=x+5 and y=3x-3 I need to get this in a ordered pair

koban [17]

9514 1404 393

Answer:

(x, y) = (4, 9)

Step-by-step explanation:

Perhaps the ordered pair you want is the one that satisfies both equations.

We can find that by equating the expressions for y:

x +5 = 3x -3

8 = 2x . . . . . . . . add 3-x to both sides

4 = x . . . . . . . . . divide by 2

y = 4+5 = 9

The ordered pair is (x, y) = (4, 9).

Tina is 4 times older than Hanna. The sum of their ages is 40. How old is Hanna?

Ksenya-84 [330]

Answer:

Hanna is 8 years old.

Step-by-step explanation:

Hanna = x

Tina = 4x

Sum = 40.

Hanna =?

Hanna + Tina = 40

4x + x = 40

5x = 40

x = 40/5

x = 8.

The accompanying data represent the actual amount (in mL) poured into a short, wide glass for individuals asked to pour 44.3 mL

kherson [118]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data below :

x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6

Mean(m) = ΣX / n

ΣX = 1066 ; n = number of observations = 18

Mean(m) = 1066 / 18

Mean = 59.22

Standard deviation (σ) :

Using the online standard deviation calculator :

σ = √(Σ(x - m)²/n-1)

σ = √264.198395

σ = 16.72

The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.

typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.

(59.22 - 19.7) mL = 39.52mL

Mean amount poured into a tall slender glass = 51.283

Mean (short wide glass) = 59.22mL

Mean (tall slender glass) = 51.283mL

Short wide glass > tall slender glass
