How did the beetle uncover the ants secret plan?

In? gambling, the chances of winning are often written in terms of odds rather than probabilities. The odds of winning is the ra

erma4kov [3.2K]

Answer:

A) The probability that the event will occur $=\frac{1}{7}$

B)The probability that the event will not occur = $\frac{6}{7}$

Step-by-step explanation:

We are given that The odds of event occurring are 1:6.

So, Number of successful events = 1

Number of unsuccessful events = 6

So, Total events = 6+1=7

a)the probability that the event will occur= $\frac{\text{Favorable event}}{\text{Total event}}$

The probability that the event will occur $=\frac{1}{7}$

b)The probability that the event will not occur = $\frac{\text{Favorable event}}{\text{Total event}}$

The probability that the event will not occur = $\frac{6}{7}$

Given: circle O with tangent AB mBC= 2x -16; mCD = x+40; mDE = x; mEB = 60 <br><br>find the x

murzikaleks [220]

Answer:

69

Step-by-step explanation:

All the given arcs cover the entire circle circumference, so their measures add up to a full 360.

(2x - 16) + (x + 40) + x + 60 = 360

4x + 84 = 360

4x = 276

x = 69

Jane max and greg are splitting a 10 ounce bag of popcorn. If they share the popcorn equally how many ounces of popcorn will eac

Sauron [17]

Since it's 3 people splitting 10 oz, we get:
$\frac{10}{3}$

Which can then be simplified to a mixed fraction:
$3 \frac{1}{3}$

So, yes, you got it right! Good job!

Which statements about the graph of the function f(x) = 2x^2– x – 6 are true? Select two options.

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

Please, share the answer options next time.

1) f(x) = 2x^2– x – 6 is a quadratic function.

2) The coefficients of this polynomial are a = 2, b = -1 and c = -6

2) Its graph opens up.

3) The x-value of the axis of symmetry and the vertex is x = -b / (2a), which here comes out to x = -(-1) / [2(2)], or x = 1/4

4) the y coordinate of the vertex is f(1/4), or -6 1/8

5) The vertex is at (1/4, -6 1/8)

6) The y-intercept is at f(0): 2(0)^2 - 0 - 6 = -6 => (0, -6)

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How

mixer [17]

To solve this, we are going to use the compound interest formula: $A=P(1+ \frac{r}{n} )^{nt}$
where
$A$ is the final amount after $t$ years
$P$ is the initial investment
$r$ is the interest rate in decimal form
$n$ is the number of times the interest is compounded per year

For the first 4 years we know that: $P=2350$ , $r= \frac{4.2}{100} =0.042$ , $t=4$ , and since the problem is not specifying how often the interest is communed, we are going to assume it is compounded annually; therefore, $n=1$ . Lest replace those values in our formula:
$A=P(1+ \frac{r}{n} )^{nt}$
$A=2350(1+ \frac{0.042}{1} )^{(1)(4)}$
$A=2350(1+0.042)^{4}$
$A=2770.38$

Now, for the next 6 years the intial investment will be the final amount from our previous step, so $P=2770.38$ . We also know that: $r= \frac{4.9}{100} =0.049$ , $t=6$ , and $n=1$ . Lets replace those values in our formula one more time:
$A=P(1+ \frac{r}{n} )^{nt}$
$A=2770.38(1+ \frac{0.049}{1})^{(1)(6)$
$A=2770.38(1+0.049)^6$
$A=3691.41$

We can conclude that Collin will have <span>£3691.41 in his account after 10 years.</span>
