PLEASE HELP MEEEEE!!!!!!!

Answer:

Cheese: $4\frac{3}{8}$
Milk: $1\frac{2}{3}$
Pasta: $6\frac{1}{4}$

Step-by-step explanation:

Cheese:

$1\frac{3}{4} = \frac{7}{4}$
Set up a proportion: $\frac{\frac{7}{4} }{4} = \frac{x}{10}$
Cross multiply, then divide: 10 × 7/4 = 17.5, 17.5 ÷ 4 = 4.375
$4.375 = 4\frac{3}{8}$

Milk:

Set up a proportion: $\frac{\frac{2}{3} }{4} = \frac{x}{10}$
Cross multiply, then divide: 10 × 2/3 = $6\frac{2}{3}$ , $6\frac{2}{3}$ ÷ 4 = $1\frac{2}{3}$

Pasta:

$2\frac{1}{2} = \frac{5}{2}$
Set up a proportion: $\frac{\frac{5}{2} }{4} = \frac{x}{10}$
Cross multiply, then divide: 10 × 5/2 = 25, 25 ÷ 4 = 6.25
$6.25 = 6\frac{1}{4}$

I hope this helps!

Two distinct solid fuel propellants, type A and type B, are being considered for a space program activity. Burning rates of the

Finger [1]

Answer:

C.I. = (2.297, 11.703)

Step-by-step explanation:

The t-statistic for difference of mean is given by,

$t=\frac{\bar{x_{1}}-\bar{x_{2}}}{\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}}}}$

Here, $\bar{x_{1}}$ = 84

$\bar{x_{2}}$ = 7

s₁ = 4

n₁ = 12

s₂ = 6

n₂ = 18

Substituting all value in formula,

We get, t = -3.541 at 28 degree of freedom.

Using this formula, we get, t = 1.5342

Therefore, based on the data provided, the 99% confidence interval for the difference between the population means $\bar{x_{1}}-\bar{x_{2}}$ is: 2.297 < $\bar{x_{1}}-\bar{x_{2}}$ < 11.703

which indicates that we are 99% confident that the true difference between population means is contained by the interval (2.297, 11.703)

Solve the following exponential equation:<br><br>5^x=2 <br><br>e^x=10

olya-2409 [2.1K]

Number 1.

$5^x=2$ , first we will take the $log$ of both of these numbers getting us,

$x=\frac{log(2)}{log(5)}$ , which then gives us that $x=0.4306777777....$

Number 2

$e^x=10$ , solve for our exponent, $2.718282^x=10$ , use the logarithmic formula, and we get,

$x=\frac{log(10)}{log(2.718282)}$ , which then we get that $x=2.302585$
