Answer:

The mortality rate is 284.744 per​ 100,000 people

Step-by-step explanation:

we are given

total number of citizens died=945,350

total population =332 million

unit rate =100000

now, we can use formula

mortality rate = [( Number of citizens died)/(total population)]*(unit rate)

so, we can plug values

and we get

Mortality rate is

=\frac{945350}{332\times 10^6} \times 100000

=284.743

So, the mortality rate is 284.744 per​ 100,000 people

Answer:

The mortality rate is 285 units of death per 100,000 people


Step-by-step explanation:

<u>945,350 people died out of 332,000,000 people. So the percentage of people who died is:</u>

\frac{945,350}{332,000,000}=0.00285*100=0.285% is the rate of mortality


<u>Now, in terms of 100,000 people, we need to multiply this mortality rate (0.285%) with 100,000:</u>

(0.285)(100,000)=285

Hence, the mortality rate is 285 units of death per 100,000 people

Heights​ (cm) and weights​ (kg) are measured for 100 randomly selected adult​ males, and range from heights of 138 to 190 cm and
mart [117]

Answer:

Best predicted value of y' = 86.16 kg

Step-by-step explanation:

Given,

n = 100

Range of heights = 138 - 190cm

Range of weight = 39 to 150 kg

x' =167.46 cm

y' = 81.44 kg

r = 0.108

p value = 0.285

y = - 105 + 1.08x

Significance level = 0.05

We reject H0 since pvalue, 0.285 is less than significance level of 0.05.

Therefore,

Given height of adult male, x = 177 cm

y = - 105 + 1.08x

The best predicted value of y' =

y' = - 105 + 1.08(177)

y' = 86.16 kg

The best predicted value of y' is 86.16kg

Triangles J K L and M N R are shown.
Dmitry [639]

Answer:

JK ≅ MN

Step-by-step explanation:

SAS states that any two sides of the angle and the angle itself, if , of two triangles are equal the two triangles are equal.

It is given that  ∠J ≅ ∠M and JL ≅ MR   i.e an angle and a side are equal. We need one more side to prove that the two triangles are equal.

If we look at the diagram closely we see that the angles J and M are formed by the sides JK & JL  and MN& MR.

It is given that JL ≅ MR  so we are left with JK ≅ MN

The true statements about the triangles RST and DEF are: (a), (d) and (e)

<h3>How to determine the true statements?</h3>

The statement ΔRST ≅ ΔDEF means that the triangles RST and DEF are congruent.

This above implies that:

  • The triangles can be mapped onto each other by rigid transformations such as reflection, translation and rotation
  • The transformation does not include dilation
  • Corresponding sides are congruent

The above means that the possible true statements are: (a), (d) and (e)
