After Biking 5 1/2 miles, Jada has travled 2/3 of ths length of hef trip. How long (in miles) is the entire length of her trip?

What is 7/12+5/6? Add the fractions, please

olya-2409 [2.1K]

Answer:

1 5/12

Step-by-step explanation:

first we have to convert the denominator(bottom number) to 12

6x2=12

Now we have to multiple 2 to the numerator(top number)

since we have to do the same to the top and bottom

5x2=10

now we add the fractions

7/12+ 10/12=17/12

now we simplify the fraction

17/12= 1 5/12

hopefully you understand how to do it.

Have a good day:)

One number is 3 time another number. If 5 is added to both the number then one of the new number becomes twice that of other new

maria [59]

Answer:

The original number is 5.

Step-by-step explanation:

If one number is x then the other is 3x.

Adding 5 to both numbers we get x + 5 and 3x + 5 and we are also given that (3x + 5) = 2(x + 5)

3x + 5 = 2x + 10

3x - 2x = 10 - 5

x = 5.

Find four consecutive multiples of 5 whose sum is 90

STatiana [176]

Answer:

15, 20, 25, 30

Step-by-step explanation:

If want to find the first multiple, we could actually use the equation: x + (x+5) + (x+5+5) + (x+5+5+5) = 90. After simplifying this term, we would get 4x+30 = 90 which then transforms into 4x=60 which simplifys to x = 15. Plug 15 into the original equation, and you would get the multiples 15 + 20 + 25 + 30 = 90.

The highest possible z-score that is still in the bottom 95% of the systolic blood pressure distribution is z =−1.645 . Use this

lawyer [7]

Answer:

(1) The value of X is, 151.13.

This score X, is the 95th percentile of systolic blood pressure scores among women. The percentile rank of this score is 95.

(2) The percentage of women have systolic blood pressure in the range 140 to 159 is 9.01%.

(3) The percentage of women having systolic blood pressure below 90 is 21.19%.

Step-by-step explanation:

The random variable X is defined as the systolic blood pressure of women.

The distribution of X is, N (110, 25²).

(1)

The value of z-score that is in the bottom 95% is, 1.645.

Compute the value of X as follows:

$z=\frac{X-\mu}{\sigma}\\1.645=\frac{X-110}{25}\\X=110+(1.645\times 25)\\X=151.125\\\approx151.13$

The value of X is, 151.13.

This score X, is the 95th percentile of systolic blood pressure scores among women. The percentile rank of this score is 95.

(2)

Compute the probability of X between 140 and 159 as follows:

$P(140$

The percentage of systolic blood pressure between 140 and 159 is,

0.0901 × 100 = 9.01%

Thus, the percentage of women have systolic blood pressure in the range 140 to 159 is 9.01%.

(3)

Compute the probability of X below 90 as follows:

$P(X$

The percentage of women having systolic blood pressure below 90 is,

0.2119 × 100 = 21.19%.

Thus, the percentage of women having systolic blood pressure below 90 is 21.19%.
