Answer:

18m

Step-by-step explanation:

Since the given traingles are similar

We get

$\frac{JK}{MN} = \frac{KL}{ML}$

$\frac{JK}{42} = \frac{21}{49}$

$JK = \frac{21 \times 42}{49}$

$JK = \frac{3 \times 7 \times 6 \times 7}{7 \times 7}$

$JK = 3 \times 6 = 18$

$JK = 18$

Hence the distance across river is 18m

Answer:

The answer is 1st point.

Step-by-step explanation:

By following the steps that is shown in the picture :

56x² - 8x - 7x + 1

1.Group pairs of terms with common factor,

(56x² - 8x) + (-7x + 1)

2.Factor the GCF from each group,

8x(7x - 1) - 1(7x - 1)

3.Use distributive property,

(8x - 1)(7x - 1)

Answer:

The 95% confidence interval estimate of the proportion of people who say that they voted

(0.67122 , 0.72798)

Step-by-step explanation:

Step(i):-

In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.

Sample proportion

$p = \frac{x}{n} = \frac{701}{1002} = 0.6996$

Step(ii)

The 95% confidence interval estimate of the proportion of people who say that they voted

$(p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )$

$(0.6996 - 1.96\sqrt{\frac{0.6996(1-0.6996)}{1002} } , 0.6996 + 1.96 \sqrt{\frac{0.6996(1-0.6996)}{1002} } )$

(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)

(0.6996 - 0.02838 , 0.6996 + 0.02838)

(0.67122 , 0.72798)

Final answer:-

The 95% confidence interval estimate of the proportion of people who say that they voted

(0.67122 , 0.72798)

Alex777 [14]

Answer:

1:17

Step-by-step explanation:

Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.

Now, arrange them in the ratio of Lunch Break to Total office time

30:510. This can be simplified to 1:17

Please check if the question is worded correctly, just in case. Because ratio questions are usually based on a part and the remaining parts of the same thing, and not part to whole.

Anyway. The answer given if for the question you have typed.

Hope this helps.

Which expression is equivalent to 6(3+0.05)?

Gnesinka [82]

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .
