I believe you solved for x, but did not plug it back into 7x-35 to get that segment’s length. The correct answer is 49.

Answer:

M; BM = 49

Step-by-step explanation:

The vertical mark between A and M and the vertical mark between M and B show that segments Am and MB are congruent. That makes point M the bisector of segment AB.

The two segments AM and MB are congruent, so their lengths are equal.

4x + 1 = 7x - 35

Subtract 7x from both sides.

-3x + 1 = -35

Subtract 1 from both sides.

-3x = -36

Divide both sides by -3.

x = 12

BM = 7x - 35 = 7(12) - 35 = 84 - 35 = 49

Answer: M; BM = 49

Ivan and kate live 40 miles apart. ivan leaves his house at 8:00
Kruka [31]
<span>Ivan DATA:
rate = 12 mph ; time = t hrs ; distance = 12t miles

</span><span>Kate DATA:
rate = 16 mph ; time = t-(3/2) hrs ; distance = 16t - 24 miles

</span><span>Equation:
12t + 16t-24 = 40 miles

</span><span>28t = 64
time = 16/7 = 2hr 17 min
Ans: 8:00 + 2hr 17 min = 10:17AM</span>

Of the 727 cases of SI, 203 received two doses of vaccine. Of 1,239 controls, 771 received two doses of vaccine for SI. What is
zysi [14]

Answer:

hello your question is incomplete below is the complete question

Case-Control Calculation Enter only numeric values into the answer line. Place a leading 0 before the decimal and remember to round to two decimal places. Note your answers for the next short essay question. Swine Influenza (SI) is a growing concern at the local Broncoville Health Department in Lawrence, Kansas. You are working for a pharmaceutical company which is developing a human vaccine against SI. You are in charge of testing the vaccine’s effectiveness. You need to determine if one or two doses of vaccine is required to provide immunity. You field test and collect the following information about the vaccine status of persons who did and did not contract SI after getting either one or two doses of vaccine. Develop a 2 x 2 table with the following information: Of the 727 cases of SI, 203 received two doses of vaccine. Of 1,239 controls, 771 received two doses of vaccine for SI. What is the likelihood of contracting SI with only one dose of vaccine?

1. Calculate the incidence of persons with one dose of vaccine for SI

2. Calculate the incidence of persons with two doses of vaccine for SI

3. Calculate the odds ratio of developing SI among those with one dose of vaccine for SI

answer : 1) ≈ 0.53 , (2)  ≈ 0.21,  (3)  ≈ 1.12

Step-by-step explanation:

cases of SI = 727

number of SI cases that received two doses of vaccine = 203

number of SI cases that received one dose of vaccine = 727 -203 = 524

controls = 1239

number of controls that received two doses of vaccine = 771

number of controls that received one dose of vaccine = 1239 - 771 = 468

I) The incidence of persons with one dose of vaccine for SI

= 524 / 992 = 0.528 ≈ 0.53

2) The incidence of persons with two doses of vaccine for SI = 203/974 = 0.208 ≈ 0.21

3) The Odds of SI in one dose group

=  524/468 = 1.119 ≈ 1.12

What is y=x+10 in Standard Form?<br><br> ASAP please, thanks!
Allushta [10]
The standard form is Ax + By = C

Given the linear equation, y = x + 10, we must transpose x to the left-hand side of the equation:

- x + y = x — x + 10

- x + y = 10

Next, we must multiply both sides by (-1) because A must be positive:

(-1) (- x + y) = 10 (-1)

This leads to:

x — y = -10 in standard form, Ax + By = C
