100 ounces = 6.25 pints

A mile unit is equal to 1760 yards. inches =mile * 63360 2*63360=126720

2 Miles = 126720 Inches

There are 36 inches in a yard

3600/36= 100

3600 inches = 100 yards

1 m = 1/1000 km

6800/1000 = 6.8

6800 m = 6.8 km

1 m = 100 cm

15000/100=150

15000 cm=150 m

a) Johnson ran yard in second= 9

1 minute = 60 second

Johnson ran yard in one minute= 9 *60= 540 yards

b) Johnson ran yard in second= 9

1 hour = 60 minutes *60 second= 1200 seconds

Johnson ran yard in one hour= 9 *1200= 10,800 yards

c) Johnson ran yard in one hour= 9 *1200= 10,800 yards

1 mile = 1760 yards

miles did he run in one hour= 10,800 / 1760 =6

Johnson ran 6 mile in one hour

If x2 mx m is a perfect-square trinomial, which equation must be true? x2 mx m = (x – 1)2 x2 mx m = (x 1)2 x2 mx m = (x 2)2 x2 m

Leno4ka [110]

An expression has numbers, variables, and mathematical operations. The equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².

<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.

A perfect square trinomial is in the form (a+b)²=a²+b²+2ab. If we compare the perfect square trinomial x²+mx+m, we will get that the value of m should be such that it satisfies the equation $m^2+2m$ . Since there is only one value that can satisfy this equation that is 2.

Therefore, the equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².

A candy company claims that 25% of the candies in its bags are colored green. Steve buys 32 bags of 32 candies, randomly selects

Luden [163]

Answer:

45.88%

Step-by-step explanation:

We have in this case a binomial distribution when p = 0.25, since the probability is 25%

. The formula that we will use in excel is BINOM.DIST, separated by commas we must put the value of x, n, p and also if it is true or false. We know that n equals 32.

In this case we need to know when x = 7, 8 and 9 and add this, and thus we will obtain the probability:

P (X = 7) + P (X = 8) + P (X = 9)

Excel formulas: = BINOM.DIST (7,32,0.25, FALSE) + BINOM.DIST (8,32,0.25, FALSE) + BINOM.DIST (9,32,0.25, FALSE)

P = 0.1546 + 0.1610 + 0.1431

P = 0.4588

Probability that steve agrees with the company's claim 45.88%
