Answer:  (92, 128)

Step-by-step explanation:

According to the Empirical rule,

If the population is normallly distributed, then 95% of the population lies within 2 standard deviations from the mean.

Given: Mean = 110

Standard deviation = 9

The interval of systolic blood pressures represent the middle 95% of males:

(110-2(9), 110+2(9))

= (110-18, 110+18)

= (92, 128)

Hence, the interval of systolic blood pressures that represent the middle 95 % of males =  (92, 128)

Answer:

its 92, 128

Answer:

X = 5

Step-by-step explanation:

Angles on a straight line=180°

180-151=29°

sum of angles in a triangle= 180°

11x-1+20-3+29=180

11x+20x-3-1+29=180

31x+25=180

31x=180-25

31x=155

divide both sides by 31

X=5

(11x-1)°= 55-1= 54°

(20x-3)°= 100-3= 97°

54°+97°+29°=180°

Step-by-step explanation:

1/2 * 1/4 = 1/8

When you divide fractions you can multiply them if you use el reciproco ( not sure how to tell it in English sorry)

Hope this help

The equivalent multiplication equation is 1/2 x 1/4.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

1/2 ÷ 4​

As, the fraction does not support division.

So, to perform the division we change the division sign into multiplication sign and reciprocate the number on the right side of division sign.

Then, 1/2 ÷ 4​

= 1/2 x 1/4

= 1/8

Hence, the equivalent multiplication equation is 1/2 x 1/4.

[tex]\huge\mathtt\purple{Answer :- }[/tex]

Let the two numbers be 'm' and 'n'

Now we can get,

1) m + n = 56

2) m - n = 10

m + n = 56

n = 56 - m

m - n = 10

By substituting n = 56 - m we get,

m - (56 - m) = 10

56 - m - m = 10

56 - 2m = 10

-2m = 10 - 56

-2m = -46

m = - 46/-2

Now, we will find 'n' by the equation 1 ,

n = 56 - m

n = 56 - 23

33 + 23 = 56

33 - 23 = 10

Hence, verified

Answer:

The finding is significant at both α = 0.05 and α = 0.01.

Step-by-step explanation:

Given that:

Null hypothesis : H0: p = 0.65 against the Alternative Ha: p < 0.65,

The test statistic ; z test = - 2.35

From the test statistic value, we can obtain the p value of the test :

To determine if the claim is significant at both α = 0.05 and α = 0.01

We compare the Zstatistic and Zcritical values

If Zstatistic < Zcritical ; then we reject H0; if otherwise, we fail to reject H0

Zcritical at 95% one tailed = - 1.645 (left tail)

Zcritical at 95% one tailed = -2.326 (left tail)

- 2.35 < - 1.645

-2. 35 < 2.326

Since, Zstatistic < Zcritical;

The finding is significant at both α = 0.05 and α = 0.01.

Answer:

Here's what we know:

n + d = 20 (there are a total of 20 nickels and dimes)

.05n + .1d = 1.4 (total change equals $1.40)

There are a couple of ways to solve this. You can go the elimination method by multiplying the second equation by an amount to get rid of a variable, or we can go substitution by isolating a variable in the first equation. I'll go with elimination in this case:

-10(.05n + .1d = 1.4) this will cause the d-variable to equal 0:

n  +  d = 20

-.5n - d = -14

------------------

.5n = 6

n = 12

Now that we know n, we can solve for d:

12 + d = 20

d = 8

Check:

.05 * 12 + .1 + 8 = 1.4

.6 + .8 = 1.4

1.4 = 1.4

Answer:

you can get 360 miles on a full tank

Step-by-step explanation:

Answer:

Every 1 Gallon will get you 30 Miles

So, if you have 12 Gallons then you can travel 360 Miles

You just multiply the amount of miles you can travel per gallon by the total amount of gallons that can be held by the gas tank. This will get you the max miles you can drive before running completely out of gas.

Answer:

15,894.06

Step-by-step explanation:

HI there!

This is a compound interest question, so we will use the formula

[tex]x = p(1+\frac{r}{n})^n^t[/tex]

P being our principle amount, $15,000 in this case,

R being our rate, or 1.25

N being our compound rate, which is semiannually, or twice a year.

T is our time, being 3.

After plugging these values in, we get

Answer:

2x^1+1

Step-by-step explanation:

Area=L X W

which means that (14x^4+7x^2) needs to be divided by 7x^2

factorise(14x^4+7x^2) which gives 7x(2x^2+1)

divide 7x(2x^2+1) by 7x^2

gives 2x^2 +1

Answer:

The area of a rectangle is (14x^4 + 7x^2) cm²

and its breadth is 7x^2 cm.

it's length is :---

[tex] = \frac{(14{x}^{4} + 7 {x}^{2})}{7 {x}^{2} } \\ = \frac{7 {x}^{2}(2 {x}^{2} + 1) }{7 {x}^{2} } \\ = (2 {x}^{2} + 1) \: c {m}[/tex]

(2x^2+1) cm is the right answer.
