$\frac{1}{2} \div 8 = x$
After LCF(Leave,change,flip) it would be
$\frac{1}{2} \times \frac{1}{8} = x$

Then you would do top times top and bottom times bottom and get
$x = \frac{1}{16}$
And if you want decimal then you can do
$1 \div 16 = x$
$x =0.0625$

Carleen deposited $16,400 in a bank account with an annual interest rate of 3.9%. How much interest was earned in 8 years?

Nesterboy [21]

The amount on interest he earned is $5116.8

Step-by-step explanation:

Given,

Principal(P) = $16400

Rate of interest(R) = 3.9%

Time(T) = 8 years

To find the interest

Formula

Simple interest = $\frac{PRT}{100}$

Hence,

The interest =$ $\frac{16400X3.9X8}{100}$

= $5116.80

A county is considering rasing the speed limit on a road because they claim that the mean speed of vehicles is greater than 30 m

DochEvi [55]

Answer:

No, at alpha equals 0.10, we do not have enough evidence to support the county's claim.

Step-by-step explanation:

We are given that a county is considering raising the speed limit on a road because they claim that the mean speed of vehicles is greater than 30 miles per hour.

A random sample of 15 vehicles has a mean speed of 31 miles per hour and a standard deviation of 4.7 miles per hour.

Let $\mu$ = true mean speed of the vehicles.

SO, Null Hypothesis, $H_0$ : $\mu \leq$ 30 miles per hour {means that the mean speed of vehicles is lesser than or equal to 30 miles per hour}

Alternate Hypothesis, $H_A$ : $\mu$ > 30 miles per hour {means that the mean speed of vehicles is greater than 30 miles per hour}

The test statistics that will be used here is One-sample t test statistics as we don't know about the population standard deviation;

T.S. = $\frac{\bar X -\mu}{\frac{s}{\sqrt{n} } }$ ~ $t_n_-_1$

where, $\bar X$ = sample mean speed of 15 vehicles = 31 mph

s = sample standard deviation = 4.7 mph

n = sample of vehicles = 15

So, test statistics = $\frac{31-30}{\frac{4.7}{\sqrt{15} } }$ ~ $t_1_4$

= 0.824

Hence, the value of test statistics is 0.824.

Now at 0.10 significance level, the t table gives critical value of 1.345 at 14 degree of freedom for right-tailed test. Since our test statistics is less than the critical value of t as 0.824 < 1.345, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region.

Therefore, we conclude that the mean speed of vehicles is lesser than or equal to 30 miles per hour which means that the county's claim is not supported.

Simplify the expression: (3 − 4i) + (7 − 6i). 4 − 2i 4 − 10i 13 − 2i 10 − 10i

yulyashka [42]

Equivalent expressions are expressions of equal values

The simplified expression of (3 - 4i) + (7 - 6i) is $10- 10i$

The expression is given as:

$(3 - 4i) + (7 - 6i)$

Remove brackets in the above expression

$3 - 4i + 7 - 6i$

Rewrite the expression by collecting the like terms

$3 + 7- 4i - 6i$

Next, evaluate the like terms

$10- 10i$

Hence, the simplified expression of (3 - 4i) + (7 - 6i) is $10- 10i$

What’s the answer to this?

Vanyuwa [196]

Answer:

answer c

Step-by-step explanation:

the two x-intercepts are (-4,0) and (2,0) so the factors of the equation are (x-2) and (x+4). if you multiply the factors it gives you the equation of the graph whic is x^2+2x-8 so c= -8 and b= 2
