CAN ANYONE HELP ME ASAP?!? PLEASEEE! I’ll give brainliest! <br> 1-4

liraira [26]

Answer:

35 degrees

42 degrees

x = 8 degrees

x = 7 degrees

Step-by-step explanation:

m <1 = 70/2 = 35 degrees

m <1 = 84/2 = 42 degrees

6 + 4 x = (9 x + 4) / 2

12 + 8 x = 9 x + 4

12 - 4 = x

x = 8 degrees

3 x - 1 = x + 13

2 x = 14

x = 7 degrees

50 points! Please help me

Inga [223]

Answer:

x = 8

y = 14

Step-by-step explanation:

2x + 6 = 4x - 10 (Corresponding angles so they're equal)

2x - 4x = -10 - 6

-2x = -16

x = 8

2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)

2(8) + 6 + 13y - 24 = 180

16 + 6 + 13y - 24 = 180

13y - 2 = 180

13y = 182

y = 14

Write and graph an equation in two variables that shows the relationship between the time t and the distance d traveled Moves 2

tiny-mole [99]

Answer:

the distance equation is

$d=\frac{2}{3}\times t$

Step-by-step explanation:

Let's assume

time in hours as 't'

distance traveled as 'd' meters

We are given

Moves 2 meters every 3 hours

So, firstly we find speed

$speed=\frac{2}{3}$

$k=\frac{2}{3}$

we know that

distance = (speed)*(time)

now, we can plug values

$d=k\times t$

now, we can plug value

$d=\frac{2}{3}\times t$

So, the distance equation is

$d=\frac{2}{3}\times t$

A standard number cube, numbered 1 through 6 on each side, is rolled 3 times. What is the probability of rolling a 2 on all thre

nikklg [1K]

Answer:

The answer is 1/216

Step-by-step explanation:

The probability of getting a 2 on a six-sided number cube is 1/6 because the number "2" appears on just one out of the six faces.

Since, the probability of getting a 2 in the first throw is independent of the probability of getting a 2 in the subsequent throws, we multiply these probabilities:

P (2, 2, 2) = 1/6 x 1/6 x 1/6

P = 1/216

Nts) in a certain population of voters, 72% of them plan to vote in favor of a new

Ganezh [65]

Answer:

Probability that 10 of them plan to vote against this piece of proposed legislation is 0.0701 or 7.01 %.

Step-by-step explanation:

Consider the event of voting against the piece as success, 'p'. So, voting in favor of the piece is failure and denoted by 'q'.

Given:

Sample size is, $n=25$

Probability of failure is, $q=72\%=0.72$

Therefore, probability of success is, $p=1-q=1-0.72=0.28$

Number of successes is, $x=10$

Now, from Bernoulli's distribution, probability of $x$ successes out of $n$ samples is given as:

$P(X=x)=_{n}^{x}\textrm{C}p^xq^{n-x}$

Here, $n=25,x=10,p=0.28,q=0.72$ . Therefore,

$P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{25-10}\\P(X=10)=_{25}^{10}\textrm{C}(0.28)^{10}(0.72)^{15}\\P(X=10)=3.269\times 10^{6}\times 2.962\times 10^{-6}\times 7.244\times 10^{-3}\\P(X=10)=70.142\times 10^{-3}=0.0701=7.01\%$

Therefore, probability that 10 of them plan to vote against this piece of proposed legislation is 0.0701 or 7.01 %.
