Answer: C. There are four groups of three tens and six ones

Step-by-step explanation:

From the options,

A. Three groups each have three tens and 4 ones.

Three tens and 4 ones equal: = (3 × 10) + (4 × 1) = 30 + 4 = 34

Therefore, 34 ÷ 3 is incorrect.

B. There are three groups of five tens and 9 ones in each group.

Five tens and 9 ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

C. There are four groups of three tens and six ones.

Three tens and six ones equal:

= (3 × 10) + (6 × 1)

= 30 + 6 = 36

Therefore, 36 ÷ 4 is correct

D. There are three groups of five tens and nine ones in each group.

Five tens and nine ones will be equal to:

= (5 × 10) + (9 × 1)

= 50 + 9 = 59

Therefore, 59 ÷ 3 is incorrect

Therefore, the correct option is C.

How to order -14.4, -14, -14 1/5 from least to greatest
ElenaW [278]
Think of  thermometer the negative degrees are the coldest so are the lowest on the vertical column

first convert -14 1/5 to decimals  =  -14.2

so the order is 

-14.4 , -14 1/5 , -14.

Write the equation of the line in slope intercept form Slope=-4 Point=(2,-4)
Andrei [34K]

Answer:

y=2x-8

or

f(x)=2x-8

Step-by-step explanation:

To write in slope-intercept form using this information, first use the point slope formula.

y-y1=m(x-x1)

m is slope.

y+4=2(x-2)

Use distributive property on the right side.

y+4=2x-4

Now, subtract 4 from both sides.

y+4-4=2x-4-4

y=2x-8

Written using function notation:

f(x)=2x-8

Hope this helps!

If not, I am sorry.

Some transportation experts claim that it is the variability of speeds, rather than the level of speeds, that is a critical fact
scZoUnD [109]

Answer:

Explained below.

Step-by-step explanation:

The claim made by an expert is that driving conditions are dangerous if the variance of speeds exceeds 75 (mph)².

(1)

The hypothesis for both the test can be defined as:

<em>H</em>₀: The variance of speeds does not exceeds 75 (mph)², i.e. <em>σ</em>² ≤ 75.

<em>Hₐ</em>: The variance of speeds exceeds 75 (mph)², i.e. <em>σ</em>² > 75.

(2)

A Chi-square test will be used to perform the test.

The significance level of the test is, <em>α</em> = 0.05.

The degrees of freedom of the test is,

df = n - 1 = 55 - 1 = 54

Compute the critical value as follows:

\chi^{2}_{\alpha, (n-1)}=\chi^{2}_{0.05, 54}=72.153

Decision rule:

If the test statistic value is more than the critical value then the null hypothesis will be rejected and vice-versa.

(3)

Compute the test statistic as follows:

\chi^{2}=\frac{(n-1)\times s^{2}}{\sigma^{2}}

    =\frac{(55-1)\times 94.7}{75}\\\\=68.184

The test statistic value is, 68.184.

Decision:

cal.\chi^{2}=68.184

The null hypothesis will not be rejected at 5% level of significance.

Conclusion:

The variance of speeds does not exceeds 75 (mph)². Thus, concluding that driving conditions are not dangerous on this highway.
