We observe that week 1 is represented by the color blue.
Therefore, you should check the bars in blue for the four employees.
We observe that the smallest z-cores is -0.5.
Therefore, Oberto has the lowest earnings for week 1.

If I have (-2, 7) and (6, y) distancia = 10 . How can I find y?

shusha [124]

Answer:

y = 13

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, y)

d = $\sqrt{(6+2)^2+(y-7)^2}$ , that is

d = $\sqrt{8^2+(y-7)^2}$ = 10

$\sqrt{64+(y-7)^2}$ = 10 ← square both sides

64 + (y - 7)² = 100 ( subtract 64 from both sides )

(y - 7)² = 36 ← take the square root of both sides

y - 7 = 6 ( add 7 to both sides )

y = 13

Find the degree of the polynomial 7a3b2 – 2a4 + 4b – 15 Degree

vesna_86 [32]

When ur polynomial has more then one variable....and this one does...the degree is the highest term degree

7a^3b^2 ....this term has a degree of 5
2a^4...this term has a degree of 4
4b....this term has a degree of 1
15....this term has a degree of 0

so the highest degree term has a degree of 5....so that is the degree of this polynomial.

now if u just had 1 variable, the degree would be the highest exponent

When do you get an answer to a system of linear equations that has one solution, no solution and infinitely many solutions?

meriva

Answer:

Step-by-step explanation:

One solution: when two lines intersect in exactly one point.

Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.

No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.
