Do you know how to graph by finding the x and y intercepts? Or can you solve for y so your equation looks like y=mx+b?

   5x + 7y ≤ -3
5x - 5x + 7y ≤ -3 - 5x
   <u>7y</u> ≤ <u>-3 - 5x</u>
      7 7
   y ≤ ³/₇ - ⁵/₇x

a recent study showed that the average high school basketball team score 76 points a game with a standard deviation of 8.4 point

krok68 [10]

Answer: 0.0766

Step-by-step explanation:

Let x be the random team scores.

Given: Mean = 76

Standard deviation = 8.4

We assume that x follows normal distribution.

The probability that a random team scores less than 64 points = P(x<60)

$=P(\frac{x-\mu}{\sigma}$

Hence, the probability that a random team scores less than 64 points =0.0766

What is the approximate length of arc s on the circle below? Use 3.14 for pi . Round

evablogger [386]

Answer:

6.3

Step-by-step explanation:

Arc length is circumference

C = 2 * pi *r

We are finding a fraction of the total arc length

A circle is 360 degrees

45 degrees / 360 degrees = 1/8

Find the total arc length and multiply by the fraction of the circle

arc length = 2 * pi * r * 1/8

= 2 * 3.14 * 8 * 1/8

=6.28

Rounding to the nearest tenth

What is a simple formula to solve a math sequence? Or a couple formulas if possible? Thanks!

-Dominant- [34]

2 normal types of sequences:

1. arythmetic sequences: each term is the same distance to the next term, example, 2,4,6,8, distance is 2

2. geometric sequences: the ratio of consecutive terms is the same, example: 2,4,8,16, ratio is 4:2=2:1, 2/1=2

the nth term is denoted by $a_{n}$
the first term is represented by $a_{1}$

for arythmetic sequences, the nth tem is
$a_{n}=a_{1}(n-1)d$ where d=distance between each term

for geometric sequences the nth term is
[tex] a_{n}=a_{1}r^{n-1} where r=ratio betwen consecutive terms

Convert 12,5% to a decimal fraction.

Decimal fractions don't exist. Do you mean convert to a decimal and a fraction?

A pea seller had some peas. He sold 40% of his stock and still had 420 peas. Originally, he had how many peas?

Zielflug [23.3K]

100-40= 60%

60% = 0.60

420/0.60 = 700

he had 700 peas
