Answer:

TU = 2.5

Step-by-step explanation:

sin 34 = 1.4/TU

Help me plz???!!!!!?!?!?

zavuch27 [327]

Answer:

Step-by-step explanation:

use slope of -2/3 and point (-4.5, 10) as input into the slope-intercept form of a line, which is y = mx + b

10 = -2/3(-9/2) + b

10 = 3 + b

7 = b

y = -2/3x + 7

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3?

VARVARA [1.3K]

Answer:

The answer is image 3.

Step-by-step explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

$let \: y = 0$

$0 = - \frac{1}{2} x + 3$

$\frac{1}{2} x = 3$

$x = 3 \div \frac{1}{2}$

$x = 6$

y-intercept :

$let \: x = 0$

$y = - \frac{1}{2} (0) + 3$

$y = 3$

Kevin’s family has a history of diabetes. The probability that Kevin would inherit this disease is 0.75. Kevin decides to take a

VladimirAG [237]

Step-by-step Answer:

We will solve the problem as follows:

Let

K=event that Keven has the disease

k=event that Kevin does not have the disease

T=event that test is accurate.

t=event that test is not accurate

We assume the events K and T are independent.

P(K)=0.75

P(k)=1-0.75=0.25

P(T)=0.85

P(t)=1-0.85=0.15

Since we know that the results of the test is negative, it can come from two possible cases:

P(K and t)=P(K)*P(t)=0.75*0.15=0.1125 (Kevin has disease, test inaccurate)

P(k and T)=P(k)*P(T)=0.25*0.85=0.2125 (Kevin does not have disease, test accurate)

Probability of negative result

= P(K and t) + P(k and T) = 0.1125+0.2125 = 0.325

Probability that Kevin does not have disease, given negative test, i.e. test accurate:

= P(k and T) / [P(K and t) + P(k and T)]

= 0.2125 / 0.325

= 0.6538
