What is a constant first difference?

1 answer:

5 0

When the x-differences are all constant, then the y-differences (or first differences) are useful in telling if a set of data is nearly linear or not.

Answer:

$Multiply~the~length~of~the~leg~by~\sqrt{2}~to~arrive~at~the~length$ $of~the~hypotenuse = 6.$

Step-by-step explanation:

$To~find~the~length~of~the~ hypotenuse,~we~multiply~the~length~of~the~leg$ $by~\sqrt{2}:$

$3\sqrt{2} *\sqrt{2}=3*2=6$

Triangle ABC had a perimeter 18 cm

Anna007 [38]

Answer:

Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.

Step-by-step explanation:

We need to find AC.

Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.

AC=

$ac = \sqrt{ab ^{2} + {bc}^{2} } \\ ac = \sqrt{ {7}^{2} } + {3}^{2} \\ ac = \sqrt{49 + 9} \\ ac = \sqrt{58 } \\ ac = 7.6$

Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.

Not really sure about my answer but hope this helped.

(PLEASE HELP) A contractor has 10 lots for sale to build on. 4 lots are greater than two acres. 6 lots are less than two acres.

charle [14.2K]

Probability that the first lot sold will be less than two acres = number of lots less than two acres / total number of lots = 6/10 = 3/5

Probability that the second lot sold will be less than two acres = remaining number of lots less than two acres / remaining total number of lots = 5/9

Required probability = 3/5 x 5/9 = 15/45 = 1/3

Which values of x satisfy the inequality 0. 5 x minus 0. 75 greater-than-or-equal-to 3. 25 x greater-than-or-equal-to 5 x less-t

telo118 [61]

To solve the problem we should know about Expressions.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The value of x in the inequality should be ≥8.

Given to us

(0.5x - 0.75) ≥ 3.25

<h3>Solve the inequality,</h3>

$(0.5x - 0.75) \geq 3.25\\\\0.5x \geq 3.25+ 0.75\\\\0.5x\geq 4\\\\x\geq \dfrac{4}{0.5}\\\\x\geq 8$

Hence, the value of x in the inequality should be ≥8.
