Answer:

a = 7.4

Step-by-step explanation:

We can find 'a' through Pythagoras theorem.

=> 8² = 3² + a²
=> 64 = 9 + a²
=> a² = 55
=> a = √55
=> a = 7.416 = 7.4

Hoped this helped.

Hi guys i need help solving −2.4n−3 and −7.8n+2.

Airida [17]

Answer:

-5 = -5.4n

Step-by-step explanation:

- 2.4n -3 = -7.8n+2

add 2.4 to both sides

which would give you

-3 = -5.4n + 2

then you would subtract -2 from both sides

and -5 = -5.4n and this is one solution

Monica [59]

Answer:

0.3085,0.2417,0.0045

Step-by-step explanation:

Given that X, the amount of money spent at shopping centers between 4 P.M. and 6 P.M. on Sundays has a normal distribution with mean $85 and with a standard deviation of $20.

X is N(85, 20)

To convert into std normal variate we use the following formula

$Z=\frac{x-85}{20}$

a) the probability that he has spent more than $95 at the mall

= $P(X>95) = P(Z>0.5)=\\0.5-0.1915\\=0.3085$

b. the probability that he has spent between $95 and $115 at the mall

= $P(95$

c. If two shoppers are randomly selected, what is the probability that both shoppers have spent more than $115 at the mall

=product of two probabilities since independent

= ${P(X>115)}^2\\= P(Z>1.5)*P(Z>1,5)\\= 0.0668^2\\=0.0045$

zalisa [80]

Answer:

<a=138°

<b=42°

<c=138°

<d=138°

<e=42°

<f=42°

Step-by-step explanation:

<a is supplementary with the 42° angle:

<a=180°-42°=138°

<b and the 42° are vertical angles, so:

<b=42°

<c and <a are also vertical angles so:

<c=<a=138°

<d and <a are corresponding angles, so:

<d=<a=138°

<e and <b are corresponding angles, so:

<e=<b=42°

<f and the 42° angle are corresponding angles, so:

<f=42°

<g and <c are corresponding angles, so:

<g=<c=138°
