Anoki bought 360 millimeters of fabric. How many centimeters of fabric does Anoki have? It’s either 360, 36.0,3.60, or 0.360
Stels [109]
Hey!


First, we need to know how many millimeters are in a centimeter.

<em>10 mm = 1 cm</em>

Okay, now we can write an equation.

<em>360 mm ÷ 10</em>

To solve this equation, we simply divide.

<em>360 mm ÷ 10 = 36 cm</em>

<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters  <em>of fabric.</em>

Hope this helps!

What’s the value of the blue dot
bixtya [17]

Answer:

-22

Step-by-step explanation:

Each line is worth 3 units

-10 - (-16) = 6 units between and there are 2 spaces

Korolek [52]

Answer:

There is no sufficient evidence to support the claim.

Step-by-step explanation:

Given the data:

7.91, 7.85, 6.82, 8.01, 7.46, 6.95, 7.05, 7.35, 7.25, 7.42

Sample size, n = 10

The sample mean, xbar = ΣX/ n = 74.07 / 10 = 7.407

The sample standard deviation, s = 0.41158 ( from calculator)

The hypothesis :

H0 : μ = 7

H0 : μ ≠ 7

The test statistic :

(xbar - μ) ÷ (s/√(n))

(7.047 - 7) ÷ (0.41158/√(10))

0.047 / 0.1301530

Test statistic = 0.361

Testing the hypothesis at α = 0.05

The Pvalue ;

df = n - 1 ; 10 - 1 = 9

Two tailed test

Pvalue(0.361, 9) = 0.7263

Since the Pvalue > α ; we fail to reject the Null and conclude that there isn't sufficient evidence to support the claim.
